Zinc Alloys For Die Casting

Zamak alloys contain approximately 4 aluminum and provide excellent die castability and good strength.

Zinc alloys for die casting.

Zinc and za alloys are commonly used for smaller die castings or die castings that require thinner sections. An excellent bearing alloy za 12 is also platable although plating adhesion is reduced compared to the conventional zinc alloys. The za alloys contain higher amounts of aluminum and offer superior strength. The hot chamber method and the cold chamber method.

Key advantages of zinc alloy die casting. Zinc alloys generally allow greater variation in section thickness and can maintain closer tolerances. From simple shapes zinc alloy die casting technology has improved the process to be able to manufacture more complex shapes. It is also a good cold chamber die casting alloy.

There are two processes for zinc alloy die casting. 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. Zinc alloy die casting is used for numerous decoration and functional applications. Thinner wall sections can be achieved compared to other metals due to high casting fluidity.

There are many benefits of using zinc alloy over others. The zinc die casting process involves the injection of molten zinc metal alloy into dies made of hardened tool steel. Za 12 often competes with za 27 for strength applications. Over a century ago molten metal was squeezed into die cast dies or die cast molds to manufacture axe heads.

Zamak alloys and za alloys. The impact strength of zinc die cast components are higher than the other common metal alloys.
