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 zinc 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 |

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 |
