1.前言含铝11%左右的锌合金具有优良的机械性能和耐腐蚀性能,ILZRO—12合金即属此类.这种合金的机械性能随冷却速度的改变而变化,获得优良机械性能的冷却条件也是清楚的.铝含量高的锌合金的机械性能稳定性差,所以有必要进行时效处理.
1. Introduction Aluminum alloy with about 11% aluminum has excellent mechanical properties and corrosion resistance, which belongs to the class ILZRO-12 alloy.The mechanical properties of this alloy change with the cooling rate changes, to obtain excellent mechanical cooling The conditions are also clear.Zinc alloys with high aluminum content have poor mechanical properties and therefore require aging treatment.
