AZ61 Customized Round Circular Magnesium-based Alloy Heat Sink
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.
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.

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.
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.
