Zinc Alloys For Die Casting

Zamak alloys and za alloys.

Zinc alloys for die casting.

It is also a good cold chamber die casting alloy. Zinc alloy die casting is used for numerous decoration and functional applications. Over a century ago molten metal was squeezed into die cast dies or die cast molds to manufacture axe heads. The hot chamber method and the cold chamber method.

An excellent bearing alloy za 12 is also platable although plating adhesion is reduced compared to the conventional zinc alloys. Za 12 is the best gravity casting alloy for sand permanent mold and the graphite mold casting process. Zamak alloys contain approximately 4 aluminum and provide excellent die castability and good strength. Za 12 often competes with za 27 for strength applications.

High production rates can be achieved. Thinner wall sections can be achieved compared to other metals due to high casting fluidity. There are two processes for zinc alloy die casting. Key advantages of zinc alloy die casting.

Zinc alloys generally allow greater variation in section thickness and can maintain closer tolerances. The zinc die casting process involves the injection of molten zinc metal alloy into dies made of hardened tool steel. There are many benefits of using zinc alloy over others. The impact strength of zinc die cast components are higher than the other common metal alloys.

There are two basic families of zinc casting alloys. Zinc and za alloys are commonly used for smaller die castings or die castings that require thinner sections.
