1. Light weight The proportion of magnesium is only 1.8G/CM3, and that of aluminum alloy is 2.7G/CM3. Magnesium alloy is 30% lighter than aluminum alloy and 80% lighter than steel. Therefore, magnesium alloys in automobiles and portable electronic products have become ideal materials for parts manufacturing.
2. Strength Magnesium alloy has an excellent strength-to-weight ratio among engineering materials such as metals and plastics.
3. Die-casting: Under the condition of maintaining a good structure, the magnesium alloy allows the wall thickness of the casting to reach a minimum of 0.6mm, which cannot be achieved by plastics at the same strength. The die-casting performance of aluminum alloy can only be compared with magnesium alloy when it is above 1.2-1.5mm. Magnesium alloy is easier to die-cast and is suitable for mass die-casting production (production speed can reach 1.5 times that of aluminum). In addition, the wear of magnesium alloy die is also lower than that of aluminum.
4. Shock absorption Magnesium has excellent hysteresis shock absorption performance, which can absorb vibration and noise. It can reduce noise transmission, prevent impact and prevent dent damage when used as an equipment casing.
5. Rigidity The rigidity of magnesium is twice that of aluminum and higher than that of most plastics. Magnesium has good resistance to stress.
6. High electromagnetic interference barrier Magnesium alloy has a good function of blocking electromagnetic waves and is suitable for the production of electronic products.
7. Good cutting performance Magnesium has better machinability than aluminum and zinc, making magnesium a metal material that is easier to cut.
8. The specific heat capacity of magnesium alloy is small, and the cooling speed of alloy liquid is fast.
9. The affinity between magnesium alloy and mold steel is small, and it is not easy to adhere to the mold.
