Zinc Alloy - ZL5

Zinc Alloy ZA5 is generally used for castings that require moderately higher strength and hardness and where dimensional stability is not an important criterion in the product application.

It is often specified for automotive applications in Europe. The alloy contains copper as specified alloying element, this promotes marginally better casting properties than the ZL3 alloy and improves mechanical properties. The nominal 1% makes the alloy more expensive and therefore its use should be restricted to applications requiring its higher properties.
