挤压铸造ZL5012合金的研究

A Study on Squeeze Casting of the-ZL5012 Alloy

ZL5012合金(Al-Zn-Mg-Fe)挤压铸件有好的表面质量和致密的组织结构,经热处理后,能获得高的机械性能,σb=490～530MP_a,δ=3～5%。此外,该合金还有固溶处理温度范围宽的特点。因此,用该合金能经济方便地挤压铸造生产优质铸件。

The ZL5012 alloy (Al-Zn-Mg-Fe) squeeze castings have high quality surface and sound structure. After heat treatment, they may be obtained high mechanical properties,ab = 490~530MPa, 6= 3~5% In addition, the solution treatment temperature range of ZL5012 alloy is wide. Therefore, We can economically and conveniently squeeze casthigh quality castings.
