Add to Cart
Magnesium alloy has low heat capacity, fast solidification speed and good die casting performance. Magnesium alloy is a good die-casting material. It has good fluidity and rapid solidification rate. It can produce parts with fine surfaces and sharp edges and corners, and can prevent excessive shrinkage to ensure dimensional tolerances.
Due to the low heat capacity of magnesium alloy, compared with the production of the same aluminum alloy castings, its production efficiency is 40%-50% higher, and the castings have stable dimensions, high precision and good surface finish.
The heat dissipation effect of magnesium alloy heat sink is far better than that of aluminum alloy heat sink, and it is rapidly replacing aluminum alloy heat sink to become the best choice for heat dissipation in various industries.
The advantages of magnesium alloy: fast heat dissipation, light weight, good rigidity, certain corrosion resistance and dimensional stability, impact resistance, wear resistance, good attenuation performance and easy recovery; in addition, it has high thermal and electrical conductivity, and is non-magnetic , Good shielding and non-toxic characteristics.
