What is EZAC?

EZAC is an Eastern Alloys trademarked zinc alloy, and is the most recently developed zinc die cast alloy. This zinc-based alloy contains specific additions of copper and aluminum to give it unique properties and characteristics when used in zinc die casting. Further details can be found at the following link: https://www.eazall.com/ezac.

EZAC is considered to be the strongest, hardest, and most creep resistant of the zinc die casting alloys. Its fluidity allows the alloy to be cast with thinner walls, as well as more complex shapes. The thinner walls in the casting design help lower weight and minimize material of the die cast part be lower cost compared to other competitive low density metals such as aluminum. As such, EZAC can be considered as a potential replacement alloy for steel stampings and aluminum die casters. EZAC has a low melting temperature, which allows it to be cast in a hot chamber die casting machine with low tooling wear.
