Abstract
The invention discloses a kind of aluminium alloys, according to poidometer, it is made of Al:8~16 part, Si:6~12 part, Fe:6~12 part, Cu:2~4 part, Mn:0.1~0.3 part, Cr:0.1~0.3 part, Zn:0.1~0.3 part, Ti:0.1~0.3 part and Zr:0.1~0.3 part.Coarse-grain layer controllability of the invention is high, component segregation is slight, alloy product high mechanical properties, and coarse grain zone is not likely to produce crackle and the smooth advantage of alloy surface.
Description
Technical field
The present invention relates to a kind of aluminium alloys and preparation method thereof, belong to Alloy Processing field.
Background technique
6063 alloys belong to Al-Mg-Si series alloy, are that the high-quality aluminum of thermally treated prestretching stretching process production closes
Golden product, and have the characteristics that preferably mechanical property, machinability, corrosion resistance.Simultaneously the alloy be oxidized easily, have compared with
Good surface quality.It is widely used on the appearance member of high-end electronic product.
In the related technology, it is 5- that one of depth often occurs in low power detection in sample of 6063 alloys after homogenization
The coarse-grain layer of 10mm, the crystallite dimension in coarse-grain layer are 10-100 times of original grain, reach 10-100mm.On ingot casting
Coarse-grain layer will lead to extruded product periphery and form cyclic annular coarse grain region, lead to the reduction of extruded product coarse-grain position mechanical property,
Extrusion is quenched rear flexible, while coarse grain zone is also easy to produce crackle.After anodic oxidation, surface easily profile with crackle occurs
The defects of piebald.To in the related technology aluminium alloy and alloy product that there are coarse-grain layer controllabilitys is low, component segregation is serious,
Alloy product mechanical property is lower, the poor deficiency of surface quality.
Summary of the invention
The object of the present invention is to provide a kind of aluminium alloys and preparation method thereof.The aluminium alloy has high mechanical properties, thick
