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.
