Zinc Alloy Ingots for Die Casting

The high strength of the zinc alloy and its hardness characteristic make it become ideal substitute for aluminum to have higher ability of machining, suppressing, pressing and assembling. The zinc alloy shows outstanding ability of shock attenuation and vibration absorbability. In general, the tooling life of zinc alloy is at least 10 times longer than aluminum die cast tooling, in addition, the tooling expenses is also cheaper

Characteristic of the aluminum alloy：

High strength and hardness
High-accuracy dimension and stability
The good filled ability of product's thin wall

Remarkable corrosion resistance
Excellent characteristic of electroplating
Excellent electric conductivity

High thermal conductance
High repaired characteristic

Abundant recycling

Aluminum Alloy Ingots for Die Casting

In numerous casting alloys, the aluminum casting part is light and has better ability to endure the higher temperature condition to operate. The aluminum die casting not only has higher intensity and rigidity, but shows the premium ability of corrosion resistance and thermolysis (Spread heat), therefore, it is the ideal products which used in the all kind of harsh environment. In general, the tooling life of aluminum alloy is much shorter than zinc die cast tooling, in addition, the tooling expenses is also higher.

Characteristic of the aluminum alloy：

Good ability to operate in high temperature environment
Remarkable corrosion resistance
High strength and hardness

Light weight
Good rigidity and intensity
Excellent electromagnetic wave covered performance

Outstanding thermolysis (spread heat)
High conductive performance

High repaired characteristic
Abundant recycling
