Product Description
China Factory Magnesium Alloy Die Casting Heatsink AZ31B AZ61 AZ91D AZ92
Description
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). Magnesium alloys are well-known for being the lightest structural alloys. They are made of magnesium, the lightest structural metal, mixed with other metal elements to improve the physical properties. These elements include manganese, aluminium, zinc, silicon, copper, zirconium, and rare-earth metals.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.

Because magnesium alloy has good thermal conductivity and low cutting force, the heat dissipation rate during processing is very fast, so the tool life is long and the amount of sticking is small, which can reduce tool costs and shorten the downtime required for tool replacement. Because magnesium is easy to cut, its chip breaking performance is very good, under normal circumstances, only one finishing process can achieve the required final surface finish.
Good heat transfer: Although the thermal conductivity of magnesium alloy is not as good as that of aluminum alloy, it is dozens of times higher than that of plastic. Therefore, magnesium alloy used in electrical products can effectively dissipate internal heat to the outside.
Application range: Magnesium alloy is used in the casing and heat dissipation parts of computers and projectors that generate high temperatures inside. The use of magnesium alloy on the casing of the TV can achieve no heat dissipation holes.
Others: magnesium alloy is 200 times higher than plastic in thermal conductivity, thermal expansion performance is only half of the plastic.
