Product Description
High Precision Magnesium Alloy Heat Sink AZ31B For Power Electronic & Semiconductor
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;
