Industrial Application Forged Magnesium Alloys Heat Sink 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.
In addition, the low density, low melting point, low dynamic viscosity, low specific heat capacity, low latent heat of phase change and low affinity with iron of magnesium alloys make it have low melting energy consumption, fast filling speed, fast solidification speed, and practicality. The advantages of short die-casting cycle and long mold life are very suitable for forming and processing using modern die-casting technology to directly produce thin-walled and near-net-shaped components with complex shapes.

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.
