Zinc Alloys For Die Casting

The zinc die casting process involves the injection of molten zinc metal alloy into dies made of hardened tool steel.

Zinc alloys for die casting.

High production rates can be achieved. Zamak 3 astm ag40a or zinc alloy 3 is the most widely used zinc alloy in north america and is usually the first choice when considering zinc for die casting for a number of reasons. Zamak alloys and za alloys. Za 12 often competes with za 27 for strength applications.

The za alloys contain higher amounts of aluminum and offer superior strength. Thinner wall sections can be achieved compared to other metals due to high casting fluidity. It is also a good cold chamber die casting alloy. Zinc and za alloys are commonly used for smaller die castings or die castings that require thinner sections.

There are many benefits of using zinc alloy over others. An excellent bearing alloy za 12 is also platable although plating adhesion is reduced compared to the conventional zinc alloys. From simple shapes zinc alloy die casting technology has improved the process to be able to manufacture more complex shapes. The hot chamber method and the cold chamber method.

Zinc alloy die casting is used for numerous decoration and functional applications. There are two processes for zinc alloy die casting. Key advantages of zinc alloy die casting. 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. The impact strength of zinc die cast components are higher than the other common metal alloys.
