Zinc vs. Magnesium alloys

One of the main differences between magnesium and zinc alloys is that zinc and zinc-aluminum alloys require lower pressure and temperatures for China Die Casting. Because of a lower casting temperature, zinc provides a much longer die life than magnesium, which can help reduce production costs.

Unlike magnesium, which requires special treatments and coatings for corrosion resistance and finishing, zinc alloys also offer excellent corrosion resistance and a better surface finish when they are ejected from the die.

Zinc and Zinc-Aluminum Alloys

When it comes to casting components with tight tolerances and areas with thinner wall sections, no other alloys compare to the zinc and zinc-aluminum alloys.

The element has a specific gravity of 7.0, making it one of the heaviest materials commonly used in die casting. Zinc is perfect for miniature die casting parts in high volume through a special hot-chamber injection process.

Like magnesium and aluminum, zinc is alloyed with other metals to provide better corrosion resistance, stability, dimensional strength and impact strength. Several of the available zinc alloys are referred to as ZAMAK, an acronym for zinc, aluminum, magnesium and copper.

Radiator Mould is the most commonly used zinc alloy, and it is sometimes exclusively used by die casters because of its tendency to be priced lower. In addition, the alloy provides a better surface finish during higher production rates, and it’s still capable of casting stable, intricate designs and complex components.
