Hot Sale Magnesium Alloy Die Casting LED Heat Sink AZ31B AZ61 AZ91D
Product Description
Magnesium alloys have advantages in heat dissipation relative to alloys. For heat sinks of magnesium alloy and aluminum alloy materials of the same volume and shape, the heat (temperature) produced by a certain heat source is easier to transfer from the root of the heat sink to the top of the magnesium alloy than the aluminum alloy. Speed, the top is easier to reach high temperature. That is, the temperature difference between the root and top of the radiator made of aluminum alloy material is smaller than that of the radiator made of magnesium alloy material. This means that the temperature difference between the air temperature at the root of the heat sink made of magnesium alloy and the air temperature at the top is larger than that of the heat sink made of aluminum alloy material, so it accelerates the diffusion and convection of the air inside the radiator and improves the heat dissipation efficiency. Therefore, at the same temperature, the heat dissipation time of magnesium alloy is not half that of aluminum alloy.
Some of magnesium's favourable properties include low specific gravity and a high strength-to-weight ratio. As a result, the material lends itself to a range of automotive, aerospace, industrial, electronic, biomedical, and commercial applications.

Magnesium (Mg), the 12th element on the periodic table, is a basic earth metal, ahead of aluminum (AL).Magnesium is one of the most abundant light metallic elements on earth, and is widely found in magnesite (magnesium carbonate), dolomite (calcium magnesium carbonate) and carnallite (magnesium potassium chloride hydrate).
As the lightest structural material, magnesium alloy has low specific gravity (about 23% of steel and 64% of aluminum) and high specific strength and stiffness.Good thermal and electrical conductivity;With good electromagnetic shielding, damping, shock absorption, and cutting and die casting process performance.
