Green 95% Mag Alloy Extrusion Profiles AZ91D Magnesium Heat Sink
CNC Machining Magnesium-based Alloy Extrusion Profiles for 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.
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.
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.

Products Display
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.
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.
