（従来の技術及び解決しようとする課題）アルミニウム
合金は、軽量で塑性加工も容易であるため、近年の軽量

なっている。(Conventional technology and problems to be solved) Aluminum alloys are lightweight and easy to plastically process, so in conjunction with the recent demand for weight reduction, they are used in many transportation equipment and machine parts. Aluminum alloys are increasingly being used in place of iron-based materials for parts that require wear resistance.
しかし、現在のアルミニウム合金の耐摩耗性はこのよう
な要求に対して必ずしも十分応えているとは言えない。However, it cannot be said that the wear resistance of current aluminum alloys necessarily satisfies these demands.
すなわち、従来、耐摩耗性アルミニウム合金はシルミン

であった。Ａｌ−３ｊ系合金は、初晶及び過共晶の硬い
Ｓｉ粒子が材料表面に分布している結果、優れた耐摩耗

度が高い程、耐摩耗性が優れる。しかし、その耐摩耗性
をもっても上記要求に対して十分とは云えない。That is, conventionally, wear-resistant aluminum alloys have been mainly cast or extruded materials of AU-8j-based alloys, typified by Silumin-based alloys. Al-3j alloys have excellent wear resistance as a result of primary and hypereutectic hard Si particles distributed on the material surface, and the higher the strength of the matrix supporting these Si particles, the higher the wear resistance. Excellent abrasion resistance. However, even its wear resistance is not sufficient to meet the above requirements.
したがって、上記のような耐摩耗性の更なる向上という
強い要求に応えるためには、この性能を更に高める必要
かあ。すなわち、８１粒子の分布を微細均一とし、マト
リックスの強度を向上させる必要がある。Therefore, in order to meet the strong demand for further improvement in wear resistance as mentioned above, it is necessary to further improve this performance. That is, it is necessary to make the distribution of the 81 particles fine and uniform and to improve the strength of the matrix.

以下に本発明髪更に詳述する。The hair according to the present invention will be explained in more detail below.
（作用）
まず、本発明における化学成分の限定理由について説明
する。(Function) First, the reason for limiting the chemical components in the present invention will be explained.

る。更に、Ｓｉ粒子微細化を促進するためにＳｒ、Ｓｂ
、Ｎａを添加するのである。The aluminum alloy of the present invention has Al2-5i system as the main component which has the best wear resistance among aluminum alloys,
In order to obtain a strong matrix supporting the Si particles, M
n, Cr-Zr, Fe, Ni-Cu, and Mg are added. Furthermore, in order to promote Si particle refinement, Sr, Sb
, Na is added.
Ｓｉは耐摩耗性確保のために必要不可欠の元素であるが
、８％未満では充分な耐摩耗性が得られず、また１７％
を超えるとその効果が飽和し、且つ加工性が劣化するの
で、Ｓｉ量は８〜１７％の範囲とする。Si is an essential element for ensuring wear resistance, but if it is less than 8%, sufficient wear resistance cannot be obtained;
If it exceeds this, the effect will be saturated and the workability will deteriorate, so the amount of Si should be in the range of 8 to 17%.
Ｍｎ、Ｃｒ、Ｚｒ、Ｆｅ、Ｎｉは、いずれも強制固溶さ

耐摩耗性を向上させる重要な元素であるので、これらの
１種又は２種を適量で添加する。Mn, Cr, Zr, Fe, and Ni can all strengthen the matrix by forcing them into solid solution.
Since these are important elements for improving wear resistance, one or two of these elements are added in appropriate amounts.
しかし、Ｍｎ、Ｃｒ、Ｚｒがそれぞれ０．５％未満。However, Mn, Cr, and Zr are each less than 0.5%.
Ｆｅ、Ｎｉがそれぞれ１％未満では、充分な耐摩耗性が
得られない。また、Ｍｎが２％超、Ｃｒ、 Ｚｒがそれ
ぞれ１％超、Ｆｅが３％超、Ｎｉが３％超では、その効
果が飽和し、且つ加工性が劣化する。If Fe and Ni are each less than 1%, sufficient wear resistance cannot be obtained. Furthermore, if Mn exceeds 2%, Cr and Zr each exceed 1%, Fe exceeds 3%, and Ni exceeds 3%, the effect is saturated and workability deteriorates.
Ｃｕ、Ｍ、ｇは同様にマトリックスを強化して耐摩耗性

る。Cu, M, and g also have the effect of strengthening the matrix and improving wear resistance, but after being forced into solid solution, heat treatment is performed to strengthen the matrix through precipitation hardening, and the purpose of the product Depending on the shape, one or two of them may be added as necessary. However, Cu is 0.5%
If the Mg content is less than 0.3%, the effect will be small;
When Mg exceeds 4% and Mg exceeds 2%, the effect is saturated and workability is poor.

Or add two types in appropriate amounts. In either case, there is no effect if it is less than 0.001%, and the effect is saturated if it exceeds 0.1%.

ある。The aluminum alloy whose composition has been adjusted as described above is rapidly cooled at a much faster rate than ordinary industrially manufactured mold ingots or continuous ingots, resulting in fine 81 grains that cannot be obtained with conventional ingots. structure, and a large amount of alloy components can be forced into solid solution. As a result, when the obtained material is processed by a normal industrial method, a material is obtained in which the Si particles are finely and uniformly distributed, the matrix that holds them is strong, and the wear resistance is extremely excellent.
