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
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 electronics industry
- Zamak 2: Zinc Alloy 2, also known as 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 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.
