GB DIN BS 96% Magnesium Heat Sink Extrusion Cooling Profile Painting Surface
Premium Quality Magnesium Extrusion Cooling Profile & Heat Sink Extrusion
Product Description
Magnesium alloy has excellent thin-wall casting performance and good specific strength, rigidity and impact resistance, which can fully meet the requirements of 3C products for high integration, lightness, miniaturization, impact resistance, electromagnetic shielding, heat dissipation and environmental protection. Therefore, the current 3C products such as mobile phones, notebook computers, digital cameras, camcorders, PDAs and other industries have also set off an upsurge in the development and application of magnesium alloy casings and parts.
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.

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.
