Tungsten Copper Heat Sinks

Tungsten copper heat sinks are extensively used as thermal mounting plates, chip carriers, flanges, and frames for RF, light emitting diodes and detectors, laser diode packages like:
pulse, single emitter, bars and complex carriers for optoelectronics amplifiers, receivers, transmitters, tunable lasers, etc.

Quantity:
tungsten Copper Heat Sinks 
 
Tungsten copper heat sinks used when a product or part needs to have a high heat resistance, 
low thermal expansion and high electrical or thermal conductivity. Tungsten copper alloy is used
to make engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat 
sinks, rocket parts and electrical contacts are all made out of tungsten copper alloy. The alloy is also made into sheet metal, 
tubing and plate metal. Tungsten copper alloy is used to make contacts for both high and low voltage electrical devices, and for
 high speed steel devices and switches
