Product Description
China Manufacturer Customize Extruded Magnesium Alloy Heat Sink AZ91D
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.
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;
