Product Description

Cold Forging Waterproof Magnesium-Based Alloy Heat Sink AZ31B AZ61

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. 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 (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).
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.
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.
