Aluminum alloy of compound and manufacturing process thereof and method for producing the same. [Prior Art] After the anode treatment of aluminum alloy, it has many excellent characteristics, so it can be applied to many different fields. For example, the anodized aluminum alloy can have light texture, good corrosion resistance and formability. Good, beautiful appearance and fashionable, it is widely used in 3C product shells, architectural curtain walls, cosmetic boxes and lampshades. However, the main problem of the anodized aluminum alloy material is that after the anode treatment, although the surface color is uniform, it has a yellowish phenomenon, and visually, the yellow color of the product tends to make the old and cheap feeling. , in turn, affecting consumers' willingness to purchase; in contrast, if the color of the product is blue, it can give people a feeling of high quality. In aluminum alloys, the precipitation phase contained in the aluminum alloy varies depending on the process. Since different precipitated phases have different electrochemical potentials, the oxide film will exhibit different color after the anode treatment. For example, when the chemical formula of the precipitated phase is Al3Fe or AlmFe, the color of the oxide film is yellowish, and when precipitated, When the chemical formula of the phase is Al6Fe, the color of the oxide film is blue. In the conventional technology, in order to obtain the desired surface color of the aluminum alloy 201250009, the main content is to control the content of impurities iron (Fe) and shixi (si) in the aluminum alloy' and to add a small amount of alloying elements [for example] Town (Mg), chromium (Cr) and manganese (Mn) help to change or stabilize the precipitate phase 'to obtain the desired surface color. In addition, in the prior art, the alloys of the alloys (usually aluminum embryos) are subjected to high temperature homogenization prior to a series of rolling processes. In the process of high-temperature homogenization, various precipitation phases (chemical formula: Al3Fe, AlmFe or Al6Fe) are converted into Al3Fe. Furthermore, 'high-temperature homogenization treatment is generally carried out by burning natural gas', so that it is easy to emit a large amount of greenhouse gases and consumes a large amount of energy. According to the above, a disadvantage of the prior art is that the surface of the finally anodized aluminum alloy is still yellowish due to the high temperature homogenization to convert various precipitated phases into AbFe; in addition, high temperature homogenization requires a large amount of Energy, increase production costs. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide an aluminum alloy and a process for manufacturing the alloy and the aluminum alloy sheet, which can make the surface of the alloy have a blue color after the anode treatment, and does not require high-temperature homogenization treatment.

'^ I 在本實施例之鋁合金中，Fe、Si、Ti、B、以及Cu之 含量係如以上表一所示，除了以上五種元素之外，鋁合金 尚包含有重量百分比小於〇·3 wt°/〇之不可避免之不純物，以 及由A1所組成之其他部分（殘部）。 此外，在上述本實施例之鋁合金之多種成分中，鐵與 矽之重量百分比滿足不等式（鐵wt%/矽再者， 上述之多種成分組成第一介金屬化合物與第'一介金屬化合 物，其中第一介金屬化合物之化學式為Al/e ’第二介金屬 化合物之化學式為Al3Fe;第一介金屬化合物為本實施例之 鋁合金的表面析出物，或本實施例之銘合金之析出相為 AleFe，藉此使得鋁合金經陽極處理後之表面色澤偏藍，以 提供使用者高表面質感之感受；另外’在本實施例中’上 述第一介金屬化合物與第二介金屬化合物之重量比更滿足 不等式 0.13<(Al6Fe/Al3Fe)<1.25。 前述鋁合金所含成分及含量限定之理由敘述如下。 在本實施例之鋁合金中，添加適量的Fe，其目的在於 201250009 提高鋁合金產品之強度，同時可形成上述化學式為Al6Fe 之第一介金屬化合物，藉此使得經陽極處理後之最終鋁合 金產品之表面色澤偏藍，進而提供使用者高表面質感之感 受。當以含量過低(低於0.30 wt%)時，則無法有效提供鋁 合金產品適當的強度。當Fe含量過高（高於0.6 wt%)時， 則鋁合金耐蝕性不佳，且表面質感亦偏暗。故在本發明中， Fe之§里較佳為〇 3〇 wt%至0.60 wt%。 在本貫施例之紹合金卡，添加適量的Si，其目的除可 提高鋁合金產品之強度外，同時亦可調整控制鋁合金之析 出相Al0Fe的形成，藉此使得如上所述之最終鋁合金產品 之表面色澤偏藍。當Si含量過低(低於〇.05 wt%)時，則鋁 合金產品中鋁之含量增加，造成整理生產成本的增加。當'^ I In the aluminum alloy of the present embodiment, the contents of Fe, Si, Ti, B, and Cu are as shown in Table 1 above, except for the above five elements, the aluminum alloy still contains a weight percentage less than 〇· 3 wt ° / 〇 inevitable impurities, and other parts of the A1 (residue). Further, in the various components of the aluminum alloy of the present embodiment, the weight percentage of iron and bismuth satisfies an inequality (iron wt%/矽, and the plurality of components described above constitute the first intermetallic compound and the first intermetallic compound, wherein The chemical formula of the first intermetallic compound is Al/e 'the chemical formula of the second intermetallic compound is Al3Fe; the first intermetallic compound is the surface precipitate of the aluminum alloy of the present embodiment, or the precipitated phase of the alloy of the present embodiment is AleFe, whereby the surface of the aluminum alloy after the anodization is blued to provide a feeling of high surface texture of the user; and 'in this embodiment' the weight ratio of the first intermetallic compound to the second intermetallic compound Further, the inequality 0.13 <(Al6Fe/Al3Fe)<1.25 is satisfied. The reason for the limitation of the components and contents of the aluminum alloy is as follows. In the aluminum alloy of the present embodiment, an appropriate amount of Fe is added, and the purpose is to increase the aluminum alloy in 201250009. The strength of the product can simultaneously form the first intermetallic compound of the above formula Al6Fe, thereby making the final aluminum alloy product after the anode treatment The surface is blue in color, which provides the user with a high surface texture. When the content is too low (less than 0.30 wt%), the aluminum alloy product cannot be effectively provided with an appropriate strength. When the Fe content is too high (above 0.6) When the wt%), the aluminum alloy has poor corrosion resistance and the surface texture is also dark. Therefore, in the present invention, Fe is preferably 〇3〇wt% to 0.60 wt%. The alloy card is added with an appropriate amount of Si for the purpose of improving the strength of the aluminum alloy product, and also adjusting the formation of the precipitation phase Al0Fe of the aluminum alloy, thereby making the surface color of the final aluminum alloy product as described above blue. When the Si content is too low (less than 〇.05 wt%), the aluminum content in the aluminum alloy product increases, resulting in an increase in the cost of finishing production.
Si含量過高（高於0.20 wt%)時，除有最終銘合金產品之表 面色澤偏黃之缺料，齡金之雜性亦不佳。故在本發 明中’ Si之含量較佳為〇 〇5 wt〇/〇至〇 2〇 wt〇/〇。 至於在本發明之鋁合金中添加適量的Ή，其目的在於 細化鋁合金中之晶粒。當Ti含量過低（低於〇 〇l wt%)時，、 將，致I呂合金產品中產生粗晶與混晶等情形，使得銘合金 產品經陽極處理後，表面產生帶狀條紋的缺陷。當Ti含量 過高（高於0.03 wt%)時，則容易產生粗大的AVn析出相， 進而使得鋁合金產品經陽極處理後，表面產生線狀條紋的 缺陷。故在本發明中，Ti之含量較佳為〇 〇1 wt%至〇 〇3 wt%。 在本實施例中，需於鋁合金中添加適量的B ,其目的 主要係用來細化鋁合金中之晶粒。當B含量過低（低於 201250009 0.0004 wt/〇)時’將導致鋁合金產品 情形，使㈣金產品二St I狀條紋的缺陷。當B含量過高（高於〇.〇〇12wt%) 口主易曰產生結團的™3粗大顆粒，進而使得鋁合金產 口面、”呈^極處理後產生線狀條紋的缺陷。故在本發明 中 B 之 3 里較佳為 〇 〇〇〇4 wt%至 0.0012 wt〇/〇。 ^至於在鋁合金中添加適量的Cu，其主要目的係用以提 冋鋁合金產品之強度，同時增加鋁合金產品之亮度。當Cu 含量過低(低於0.05 wt%)時’則效果不彰。當cu含量過高 (高於0.2 wt%)時，則鋁合金產品容易產生嚴重腐蝕。故在 本發明中’ Cu之含量較佳為〇 〇5 wt%至〇 2 wt〇/〇。 請參照第1圖，其係繪示製造鋁合金(鑄胚）之製程的 流程圖’用以製造上述之鋁合金。製造紹合金之製程1〇〇 係開始於步驟102 ’製備溶融紹合金。炼融紹合金包含有 實質等同於上述鋁合金之多個成分，亦即：0.30〜0.60 wt°/〇 之鐵、0.05〜0.20 wt%之石夕、0.01〜0.03 wt%之鈦、 0.0004〜0.0012 wt%之硼、〇.〇5〜0.2 wt%之銅、0.3 wt%以下 之不可避免之不純物、以及由鋁所組成之殘部。此外，鐵 與矽之重量百分比亦滿足不等式（鐵wt%/矽wt%)>4。 完成步驟102之後，製造鋁合金之製程100繼續進行 步驟104，以預定速度澆鱗上述熔融鋁合金。並於澆鑄過 程中以預定水量提供冷卻水至熔融鋁合金，藉以形成鋁合 金。上述澆鑄之預定速度為每分鐘40 mm至每分鐘70 mm，而預定水量則為每小時200 m3至每小時300 m3。 而在完成步驟104之後，上述之多個成分於鋁合金中 201250009 組成第一介金屬化合物與第二介金屬化合物’其中第一介 ，金屬化合物之化學式為A^Fe’第二介金屬化合物之化學气 -為Alje。而經陽極處理之後，銘合金之表面可具雋偽藍^ 色澤。此外’上述第一介金屬化合物與該二介金屬化入物 之重量比亦滿足不等式O.UqA^e/A^eK1.25。 ° 請參照第2圖’其係繪示製造紹合金片材之製程的# 程圖，用以將上述之銘合金所組成之銘胚軋延成銥合金$ 材。在製造鋁合金片材之製程200中’首先進行步嵊202， 以製備鋁胚。其中’銘胚係由上述之紹合金所組戍，亦g I呂合金包含：0.30〜0.60 wt%之鐵、0.05〜0.20 wt%之石夕 0.01 〜0·03 wt%之鈦、0.0004〜0.0012 wt〇/❶之硼、0.0S〜〇 2 〇 之銅、0.3 wt%以下之不可避免之不純物、以及由lg所組成 之殘部。上述成分中之鐵與矽之重量百分比同樣滿足以上 所述之不等式（鐵〜％/矽wt%)>4。而上述成分所紐成之 第一與第二介金屬化合物之化學式分別為Al6Fe與Ai3Fe， 其中第一介金屬化合物與第二介金屬化合物之重量比滿足 上述之不等式 〇.13<(A16Fe/A13Fe)<1.25。 接著進行步驟204 ’以於第一預定溫度軋延上述之鋁 胚，藉此獲得熱軋延鋁板。在步驟204之中，第一預定溫 度為500°C至350°C，且上述於第一預定溫度軋延紹胚之裁 減量為50%至80%。 在完成上述之步驟204之後，製造鋁合金片材之製程 200繼續進行步驟206，於室溫軋延上述之熱軋延紹板，藉 此獲得冷軋延鋁片’其中於室溫軋延熱軋延鋁板之裁減量 為 50%至 80%。 201250009 最後，製造鋁合金片材之製程200進行步驟2〇8，^ 於第二預定溫度對上述冷軋延鋁片進行退火製程，藉此 得鋁合金片材。上述第二預定溫度可為2〇〇^石Μ。。曰此獲 L至400 C，且 退火製程持續之時間可為1小時至12小時。 以下則以實際之實施例與比較例更具體地說明本發 明，惟本發明的範圍不受此些實施例之限制。° 製備紹合金板材 實施例 首先，於溫度740°C熔化鋁回收錠，以製備溶气紹人 金。調配上述熔融鋁合金之組成成分，使犋 :’ σ 乂评熔融鋁合金中 鐵所佔之重量百分比為〇.54wt%，石夕所佔之舌 百 比 0.06wt% ’而鈦所佔之重量百分比為〇.〇2 *''' uzwt/。’硼所佔之重When the Si content is too high (above 0.20 wt%), in addition to the lack of material in the surface of the final alloy product, the goldiness of the age is also poor. Therefore, the content of Si in the present invention is preferably from 〇 5 wt 〇 / 〇 to 〇 2 〇 wt 〇 / 〇. As for the addition of an appropriate amount of niobium to the aluminum alloy of the present invention, the purpose is to refine the crystal grains in the aluminum alloy. When the Ti content is too low (below 〇〇l wt%), it will cause coarse crystals and mixed crystals in the I-alloy product, so that the surface of the alloy will be strip-shaped after the anode treatment. . When the Ti content is too high (greater than 0.03 wt%), coarse AVN precipitates are easily generated, and the aluminum alloy product is subjected to anodization to cause defects in linear stripes on the surface. Therefore, in the present invention, the content of Ti is preferably from wt 1 wt% to 〇 〇 3 wt%. In this embodiment, an appropriate amount of B is added to the aluminum alloy for the purpose of refining the crystal grains in the aluminum alloy. When the B content is too low (below 201250009 0.0004 wt / 〇), it will lead to the case of aluminum alloy products, making the defects of (4) gold products two St I-like stripes. When the B content is too high (higher than 〇.〇〇12wt%), the mouth is easy to produce agglomerated TM3 coarse particles, which in turn causes the aluminum alloy to produce a defect in the surface of the mouth, which results in a linear stripe after treatment. In the present invention, B is preferably 〇〇〇〇4 wt% to 0.0012 wt〇/〇. ^ As for adding an appropriate amount of Cu to the aluminum alloy, the main purpose is to improve the strength of the aluminum alloy product. At the same time, the brightness of the aluminum alloy product is increased. When the Cu content is too low (less than 0.05 wt%), the effect is not good. When the cu content is too high (above 0.2 wt%), the aluminum alloy product is prone to severe corrosion. Therefore, in the present invention, the content of Cu is preferably from 〇〇5 wt% to 〇2 wt〇/〇.

In addition, the weight percentage of iron and bismuth also satisfies the inequality (iron wt%/矽wt%)> 4. After the step 102 is completed, the process for manufacturing the aluminum alloy 100 proceeds to step 104 to squash the molten aluminum alloy at a predetermined speed, and supplies cooling water to the molten aluminum alloy in a predetermined amount of water during the casting process, thereby forming an aluminum alloy. The casting speed is 40 mm per minute to 70 mm per minute, and the predetermined water volume is 200 m3 per hour to 300 m3 per hour.

In the above-mentioned component Yuming alloy, the first intermetallic compound of the formula Al0Fe and the second intermetallic compound of the formula Alje are formed. Further, the weight ratio of the first intermetallic compound to the second intermetallic compound is 125. Subsequently, the above-mentioned blank was started to be rolled at the first-predetermined temperature of 500 ° C to obtain a hot-rolled aluminum plate, and the average reduction was 65% (co-roll rolling, phase (5) per pass). Then, the above-mentioned hot rolled sheet 33 was rolled at room temperature to obtain a cold rolled sheet. After a cumulative multi-pass rolling, the amount of cut was 8 G%. Then put 12 201250009 this ^ rolling delay correction on the outline. The second predetermined hour of the annealing process of 'c" obtains the alloy sheet of the alloy for anodizing to obtain the final title of the final aluminum alloy product: 1976 (L*a*b) color difference cut The phase difference and the color difference series according to CIE are shown in the following Table 2 Comparative Example 1 and the process conditions equipment comparison example - the alloy production port. w to obtain the comparative example - the final Ming and Shi Xi's heavy 曰The difference between the above and the embodiment is that the iron of the second example of the embodiment is two ==.= and one', and the age of the comparison process is required to be (4) become the analysis of the product. Production =: noodles, phase, and the phase difference between the phase and the color of the finished product through the anode. Please look at the two sides of the color, the color is good, the color is thicker, compared with the second sample, the second two: the comparison of the steps in the example Example 2: Ming alloy sheet 苴 / 丁°二理' to obtain the final aluminum alloy product of Comparative Example 2, the comparative example 2 is identical to the alloy composition of the example. Comparative Example 2: The difference of the above embodiment lies in the casting parameters Different, in the embodiment, it is greater than 4〇mm per minute The molten aluminum alloy was cast at a speed, and in the first comparative example, the corresponding casting parameter was less than 40 mm per minute; in addition, after analysis, it was found that in the second comparative example, the main phase composition of the aluminum embryo in the process was Alje phase. After the anode of the metallurgical rolled product is subjected to anodization, the surface color of the final aluminum 13 201250009 alloy product is poor and yellowish, and the relevant precipitation phase and color difference are listed in the following Table 2. Comparative Example 3 is the above embodiment. The aluminum alloy sheet of Comparative Example 3 was prepared and subjected to anodization to obtain the final aluminum alloy product of Comparative Example 3, wherein Comparative Example 3 and the alloy composition of the Example were identical; Comparative Example 3 The difference from the above embodiment is that the aluminum embryo obtained in the third embodiment is subjected to high-temperature homogenization treatment before the hot rolling or cold rolling process described above is performed. Further, after analysis, it is known that In the third example, the main phase composition of the aluminum embryo in the process is Al3Fe phase, and the surface of the metallurgical rolled product is anodized, and the surface color of the final aluminum alloy product is not good. Yellow, the relevant precipitation phase and color difference are listed in the following Table 2.

The higher the value, the brighter the color, and the darker the color. The difference in color of a* is used to regulate the surface color of the product to be reddish or greenish. The larger the value, the more the color is red. Otherwise, the more green, the more. As for the color difference of b*, it is used to regulate the yellow or blue color of the surface of the product. The larger the value, the more the color is yellow, and the more the blue color. 201250009 According to the contents shown in Table 2 above, in Comparative Example 1, since the weight percentage of iron and bismuth is less than 2, the main precipitate phase of the aluminum embryo is the α-Al-Fe-Si phase, thereby making the comparative example 1 The b* color difference (2.55) of the surface color of the final aluminum alloy product is much larger than the b* color difference (0.2) of the surface color of the final alloy product of the embodiment, so the surface color of the final aluminum alloy product of Comparative Example 1 is excessively yellowish. . In Comparative Example 2, the b* color difference (1.3) of the surface color of the final aluminum alloy product of Comparative Example 2 is still much larger than the b* color difference of the surface color of the final aluminum alloy product of the example in the second embodiment due to the difference in process parameters. The value (0.2), so the surface color of the final aluminum alloy product of Comparative Example 2 is still yellowish. As for the third comparative example, since the aluminum embryo is subjected to high-temperature homogenization treatment before the hot rolling, the main precipitate phase is the Al3Fe phase. Therefore, after the anodizing treatment, the b* color difference (1.1) of the surface color of the final aluminum alloy product of Comparative Example 3 is still much larger than the b* color difference (0.2) of the surface color of the final aluminum alloy product of the embodiment, and comparison is made. The surface color of the final aluminum alloy product of Example 3 is still yellowish. In summary, as described above, the final anodized aluminum alloy can be obtained by controlling the alloy composition in the aluminum alloy, controlling the process parameters for manufacturing the aluminum alloy, and controlling the hot rolling reduction and the cold rolling reduction in the aluminum alloy sheet process. The b* color difference of the sheet is less than 0.2, that is, the surface color of the final aluminum alloy product can give the user a feeling of bluish color and high texture.
