Zinc Casting Metals

Zinc alloy characteristics:

• High strength and hardness
• Excellent electrical conductivity
• High thermal conductivity
• Low cost raw material
• High dimensional accuracy and stability
• Excellent thin wall capability
• Ability to cold form, which eases joining
• High quality finishing characteristics
• Outstanding corrosion resistance
• Full recyclability

Zinc’s high strength and hardness lends itself to many solutions and it’s the ideal alternative to machined, pressed, stamped, and fabricated components.

Applications for Zinc:

• Complex net-shaped zinc housings, with precise thin walls offer excellent electrical performance and shielding properties
• Our proprietary multi-slide die casting process and superior thin-wall capabilities make us the foremost supplier of zinc components for broad range of consumer electronic devices
• The castability of zinc, its wear resistance, and structural integrity make it perfect for the creation of the multi-faceted, highly complex shapes used in automotive safety and electronics industry

• Zamak 2

  Zinc Alloy 2, also known as Kirksite or Zamak 2 (ASTM AC43A), is the highest strength and hardness of the Zamak family. 

• Zamak 3

  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 5

  Zamak 5 (ASTM AC41A) or Zinc Alloy 5, is the most widely used zinc alloy in Europe.

• Zamak 7

  Zamak 7 (ASTM AG40B), or Zinc Alloy 7, is a modification of Zamak 3. It is a high-purity alloy containing lower magnesium content and has a tighter impurities specification. This results in improved casting fluidity, ductility and surface finish.

• ZA 8

  ZA-8, or zinc aluminum alloy, contains significantly more aluminum than the Zamak group of alloys. ZA-8 contains approximately 8.4% aluminum and is the only ZA alloy that can be hot-chamber die cast, an important consideration when selecting a material for a component. 

• ACuZinc5

  ACuZinc5 is an alloy researched and developed by General Motors. It is best known for its creep performance, surface hardness, and lubricity.

• EZAC

  EZAC is a hot-chamber zinc die casting alloy with superior creep resistance, high yield strength, and high hardness.

• ZA 27 - Zinc Aluminum

  ZA-27, or zinc aluminum alloy, contains significantly more aluminum than the Zamak group of alloys. The number 27 represents the approximate percentage of aluminum.

• Zinc Creep

  Zinc creep is the time-dependent strain that takes place under a given load.
