Product Description

OEM/ODM Manufacturer Magnesium Extrusion Heat Sink AZ91D by Die Casting

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.

Moreover, the performance of magnesium alloy die castings is excellent, and the effect of substituting steel, aluminum alloy, plastic and other parts under normal conditions of use is very good. While realizing the light weight of the product, it also enables the product to have excellent special functions, and after the magnesium alloy die casting is scrapped, it can be directly recycled and reused, which meets the requirements of environmental protection. Therefore, magnesium alloys with excellent comprehensive properties are known as the "21st Century Metal" and are widely used in automobiles, computers, communications and other broad fields.

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.

Magnesium (Mg), the 12th element on the periodic table, is a basic earth metal, ahead of aluminum (AL).Magnesium is one of the most abundant light metallic elements on earth, and is widely found in magnesite (magnesium carbonate), dolomite (calcium magnesium carbonate) and carnallite (magnesium potassium chloride hydrate).
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.
