AZ31B AZ61 AZ91D AZ92 Magnesium Heat Sink Die Casting ASTM & AISI

Magnesium-Based Alloy Heat Sink AZ31B AZ61 AZ91D AZ92 By Die Casting

Product Description

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.
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.

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 dissipation: The thermal conductivity of general metals is hundreds of times that of plastics. The thermal conductivity of magnesium alloys is slightly lower than that of aluminum alloys and copper alloys, and much higher than that of titanium alloys. The specific heat is close to water, which is the highest among common alloys.
