Customized Extruded Heat Sink Profiles ZK60M Mg alloy extrusion profile
Industrial Application Forged Magnesium Alloy Extrusion Profiles Heat Sink AZ91D
Magnesium alloy is the lightest metal structural material, its density is 1.75-1.90s/cm3; its specific strength is higher than aluminum alloy and steel, and slightly lower than the highest specific strength fiber reinforced plastics; its machinability is excellent, easy to process and The processing cost is low, and the processing energy is only 70% of aluminum alloy; its corrosion resistance is much better than that of low-carbon steel, which has exceeded the die-cast aluminum alloy A380; its vibration damping and electromagnetic shielding properties are far better than aluminum alloy.
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; 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.
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.

Products Display
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.
