ZL3 Datasheet

Zinc Alloy ZA3 – a general purpose alloy, ZL3 is primarily used for producing castings for a variety of applications on a hot chamber pressure diecasting machine. The alloy’s mechanical and physical properties make it ideal for use in castings for the engineering and automotive industry, household equipment and utensils, office equipment, builders’ hardware, locks and toys. ZL3 is easily machined, buffed, polished, lacquered and electroplated for decorative or functional purposes. When designing a stressed component using ZL3 designers should refer to the alloy’s properties, at elevated temperatures, after natural or artificial ageing and the alloy’s creep properties.
