Customize Processing High-Density Magnesium Alloy Heat Sink AZ31B
Product Description
Heat sinks are thermally conductive components or devices that absorb and dissipate heat generated by electronic components. Heat sinks cool high-powered devices to prevent overheating. The reliability of electronic components is generally reduced by the square of an increase in temperature. For example, doubling the ambient temperature around a component renders the component 25% less reliable than at the lower temperature. Heat sinks are therefore essential in dissipating generated heat and improving component longevity.
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.
Weight: magnesium alloy is 36% lighter than aluminum alloy, 73% lighter than zinc, and 77% lighter than steel.
Specific strength: magnesium alloy is equivalent to aluminum alloy and steel, much higher than fiber reinforced plastics.
Wear resistance: the wear resistance of magnesium alloy is much higher than that of die-cast aluminum alloy A380.
Damping performance: magnesium alloy is 30 times higher 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.
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.
