In addition, aluminium alloy of the present invention, except above-mentioned element, also contains inevitable impurity and Al.For example, in not damaging the scope of invention effect, can contain on a small quantity Ti, Zr, Zn.The scope of not damaging invention effect refers to below 0.05%.
Eutectic Si effects on surface proterties, wearability exert an influence, and therefore, the homogeneity of these characteristics is to be decided by the size of the eutectic Si of extruded material and forged material and distribution.That is, aluminium alloy of the present invention is by controlling each content that form such as Si, obtains good extrudabilityly and forge processibility, in addition, by controlling size and the distribution of eutectic Si, prevents by the deviation in the former of surface texture and position thereby the characteristic that causes.Thus, by the present invention, can obtain with high productivity extruded material and the forged material of characteristic homogeneous.
By Ss and Sc are controlled as Sc-Ss≤15 μ m
2, make the surface texture of extruded material good, and can suppress to extrude the skewness of the wearability characteristic of top layer sidepiece and central part.About eutectic Si size, Ss refers to the eutectic Si size of take when the degree of depth of vertical Shang Ju top layer, the cross section 50 μ m of the length direction with extruded material is observed central side in benchmark, the visual field of 100 times at opticmicroscope.Ss measures 4 positions with central angle every 90 degree in the same visual field, with maximum value wherein, is as the criterion.Sc refers to the eutectic Si size of the central part in the extruded material cross section of observing in the visual field of 100 times of opticmicroscopes.Eutectic Si size in the present invention refers to the crystallization area of eutectic Si.
In addition, by making the eutectic Si in extruded material be of a size of 20 μ m
2below, can suppress surperficial roughness.In addition, in order to obtain wearability, the grain number of eutectic Si is 1000～3000/mm
2.The size 20 μ m of eutectic Si
2following grain number is lower than 1000/mm
2time, the effect of the wearability after forging is little.The grain number of eutectic Si surpasses 3000/mm
2time, hinder extrudability and forging processibility.
It should be noted that, about the creating conditions and being modifiedly all not particularly limited of the aluminium alloy in the present invention, modifiedly common creating conditions, according to purposes, select down.
In the situation that using extrusion pin as forged article, the processibility in forging process can exert an influence to the hardness of material.Thus, modified F, T1, the O of being preferably of extrusion pin of the present invention, further preferred modified is O.
In addition, the modified characteristic as required respectively after forging is selected, but is preferably T6 in the present invention.
[embodiment]
Based on embodiment, describe the present invention in detail, but the invention is not restricted to this.

Obtain after the ingot bar of diameter 220mm, this ingot bar is implemented in to the homogeneity processing of carrying out heating in 4 hours at 490 ℃.This ingot bar is extruded by 1 hole of 500 ℃, made the pole of extruding of diameter 30mm.
The extruded material of this sample, the degree of depth of take at the cross section Shang Ju top layer 50 μ ms vertical with length direction is benchmark, in the visual field of 100 times of opticmicroscope, observes central side.In the same visual field, with central angle, every 90 degree, measure 4 positions, measure its maximum eutectic Si size (Ss).In addition, the central part in extruded material cross section is observed in the visual field of 100 times of opticmicroscopes to eutectic Si size (Sc).It should be noted that, eutectic Si particle size and number are analyzed by Engineering Co., Ltd. of Asahi Chemical Industry software processed " image analysis software A is as く ん ".About surface texture, while drawing surface with the pencil of HB, situation about not scraping is made as to qualified " zero ", situation about scraping is made as to defective " * ".Show the result in table 2.The situation that reaches prescribed value is qualified, and the situation beyond prescribed value is defective.
Then, this is extruded to pole and at 400 ℃, carry out the anneal of 5 hours, obtain O material.When forging evaluation, confirmed that eutectic Si size and number are in scope of invention.
Then, this is extruded to pole along its length with the length cutting of 100mm, implement the upsetting of working modulus 80%.Forged article is carried out at 520 ℃, after the solution treatment of 2 hours, with the warm water of 50 ℃, quench at once.The artificial aging of carrying out at 180 ℃ again 10 hours is processed, and obtains the modified of T6.
At this, the working modulus of upsetting is with (r1-r2)/r1 * 100, to calculate and the value that obtains in Fig. 1.
The outward appearance that the above-mentioned tested alloys forged article obtaining is like this carried out after tension test, upsetting is observed and wearing test.The results are shown in table 3.
(1) outward appearance after upsetting
Observe the outward appearance after 80% upsetting, the situation of not observing crackle is made as to qualified (=be labeled as " zero "), the situation of observing crackle is made as to defective (=be labeled as " * ").
(2) tension test
Tension test sheet be take the mode of extruding the length direction that excellent length direction is test film and is gathered, and makes JIS4 test film, tests.As evaluation, tensile strength (TS) is qualified for 300MPa is made as above, will be made as defective lower than this value.
(3) wearing test
By large more formula wearing test, evaluate specific wear amount.At this, as test conditions, lubricating oil is gear oil (75W-90), and making subject material is SCM415, and making frictional distance is 1200m, and making load is 19kgf.As the evaluation of rub(bing)test, by specific wear amount, be 5.0 * 10
-9it is qualified to be below made as, and will be made as over this value defective.
