Why Aluminum Alloy as Housing Material

We found that aluminum enclosures offer the following advantages over other material enclosures:

1. The aluminum housing has the best performance in the automobile processing process due to its small elastic coefficient and no spark caused by collision friction. 

2. Aluminum housing shall be free of alloy material pollution, toxicity and volatile alloy material in surface oxide layer. 

3. The aluminum housing is less dense and lighter than other alloy materials. 

4. The aluminum housing has strong plasticity and good productibility, which has good advantages for manufacturing design. 

5. Aluminum shell adopts two treatment processes of heat and cold, with strong corrosion resistance. 

6. Aluminum housing has good forging characteristics. 

7. The aluminum housing has good extensibility, can be designed with many metal elements in light alloy, and the material is high quality. 

8. Good surface treatment properties for aluminum housing. 

9. Aluminum shell has stable chemical property, no magnetism, and can be repeatedly recycled. It is a good recyclable metal material

Aluminum shell is a kind of shell formed by aluminum alloy profile material, which is widely used in instrument equipment, instrument panel, electronic device, communication, automation technology, sensor, smart card, industrial automation, precision machine equipment and other fields. It is the best enclosure fitting for current electronic equipment.
