Zinc alloy of high strength and hardness of the properties that make it become mechanical processing, suppression, stamping and assembling department product ideal substitute compared with aluminum casting alloy, zinc alloy show a more excellent shock absorption ability and vibration absorption ability. Zinc alloy die casting die life long (average about 60 million - 80 million die times above) and open mold charge is aluminum alloy is low.
| Zinc alloy characteristics： |
| ◆ High strength and hardness ◆ High precision size and stability ◆ High quality shaping characteristics |
| ◆ Excellent electrical conductivity ◆ Good thin-walled filling ability ◆ Outstanding corrosion resistance |
| ◆ High heat conductivity ◆ Sufficient recyclable sex ◆ Sufficient recyclable sex |
|
| ◆ Excellent electroplating characteristics |

In numerous die-casting alloy die casting light weight and stacking-type can bear high operating temperatures. Aluminum casting parts with high strength and rigidity and excellent corrosion resistance and heat capacity, therefore is harsh environment with the ideal products. Zinc alloy die casting die life is short (average about 50,000-8 million die times fluctuation open mold) and zinc alloy charge is costly.
| The characteristics of aluminum alloy： |
◆ High-temperature operation ◆ High-temperature operation ◆ High conductivity
◆ Outstanding corrosion resistance ◆ Excellent electromagnetic shielding performance ◆ Good nap forming characteristics
◆ Very good strength and hardness ◆ Very good strength and hardness ◆Sufficient recyclable sex
◆ Light weight |
