Metal Foam Materials for LED Heat Sinks

Short Description:

LEDs are energy-efficient light sources and are popular with designers because of their small size. However, they can only be truly called “small” when no thermal management is involved. Although compared with incandescent lamps, its operating temperature is much lower, but with the rapid development of the LED industry, more and more high-power products were born, a large amount of heat seriously affects the life of the LED lighting system, LED as a bottleneck in the development of environmentally friendly lighting.

    Product Description
    Nickel foam is a kind of excellent performance acoustic material, electrode material, catalytic material, also can be used as filter material, magnetic current conductor to deal with magnetic particles in fluid. It has high acoustic absorption coefficient in high frequency; its acoustic performance in low frequency can be improved through the design of acoustic structure. Nickel foam is also one of the electrode materials for manufacturing cadmium-nickel batteries and hydrogen-nickel batteries.
    Surface quality: flat surface, no scratches, no cracks, no breakage, no oil, no oxidation
    Color: silver gray with metallic luster.
