目前,金属锌不再是只具有中等强度而限于用作轻负荷的压铸件了。新的铸锌合金的强度比铸铁大,硬度比青铜或铝高,目前正在进行重载应用方面的研究。铸造工业通常是指铁基铜基和铝基合金的铸造。现在,出现了另一种新的铸造合金——Zn-Al合金系,它的应用范围可与黑色金属和其它的有色金属竞争。这种铸造合金具有许多特性,它们能满足铸件所必需 At present, zinc metal is no longer limited to medium-intensity die-castings for light loads. The new cast zinc alloy is stronger than cast iron and harder than bronze or aluminum, and heavy-duty applications are currently underway. The foundry industry usually refers to the casting of iron-based copper and aluminum-based alloys. Now, there is another new casting alloy - Zn-Al alloy system, its scope of application with ferrous metals and other non-ferrous metals competition. This casting alloy has many features that are necessary for the casting
