Zamak 3 Zinc Alloy

A zinc die-casting alloy long favored for dimensional accuracy on precision small parts.

Example: cast Zamak 3 Zinc Alloy

What is it?

The standard general-purpose zinc die-casting alloy.

Key behavior

Good dimensional stability and impact strength, with a very low melting point that enables fine casting accuracy.

Why choose it

Precision small parts and housings needing good dimensional accuracy at a reasonable cost.

Applications

Door hardware, precision gears, decorative emblems, connector housings.

Casting notes

Low melting point supports long tool life and tight casting accuracy on repeated production runs.
