ZL3 is a pressure die casting zinc base alloy which conforms to BS EN 1774 and is one of a family of versatile high grade zinc alloys manufactured by Brock Metal.


ZL3 is a general-purpose alloy and is primarily used for producing castings for a variety of applications on a hot chamber pressure die casting 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, builder’s hardware, locks, toys, giftware etc. ZL3 is easily machined, buffed, polished, lacquered and electroplated for decorative or functional purposes.

When designing a stressed component using ZL3 further reference should be made to the alloys properties, at elevated temperatures, after natural or artificial ageing and the alloys creep properties.
