分辨锌合金锭质量的实用方法

Practical Method for Distinguishing Quality of Zinc Alloy Ingot

简述了锌及锌合金的用途、常用牌号及锌合金锭质量对铸件质量的影响。介绍了分辨锌合金锭质量的主要方法(表面质量、化学成分、硬度、晶粒度及断口颜色等)和其他辅助方法。通过对锌合金锭质量的把关,可以有效保证产品抛光和电镀的合格率。

Applications and commonly used brands of zinc and zinc alloy, and effect of quality of zinc alloy ingot on product castings were briefly described. The essential and auxiliary methods used for distinguishing quality ( surface quality, chemical composition, hardness, grain size, and fracture color) of zinc alloy ingot were introduced. The percent of qualified products subjected to polishing and electroplating can be effectively ensured through guaranteeing quality of zinc alloy ingot.
