Heat sink is a device to dissipate heat to the heat-prone electronic components in electrical appliances, mostly made of copper, brass or bronze in the form of plate, sheet, multi-piece, etc., such as the CPU central processing unit in the computer to use a large heat sink, the power supply tube, line tube in the TV, amplifier tube in the amplifier are to use heat sink. In general, the heat sink is coated with a layer of heat-conductive silicone grease on the contact surface of the electronic components and the heat sink, so that the heat from the components can be conducted to the heat sink more effectively and then distributed to the surrounding air by the heat sink. The copper and copper alloy foil produced by CIVEN METAL is a special material for heat sink, which has the characteristics of smooth surface, good overall consistency, high precision, fast conduction, and even heat dissipation.Copper Foil Brass Foil Bronze Foil High-precision RA Copper Foil High-precision RA Brass Foil *Note: All the above products can be found in other categories of our website, and customers can choose according to the actual application requirements.
