Yiwu Yitech's Tungsten copper heat sinks is a term for a component or assembly that transfers heat generated within a solid material to a fluid medium, such as air or a liquid. Examples of heat sinks are the heat exchangers used in refrigeration and air conditioning systems and the radiator (also a heat exchanger) in a car. Heat sinks also help to cool electronic and optoelectronic devices, such as higher-power lasers and light emitting diodes (LEDs).
Our tungsten-copper composites are used in electronic packaging thermal management applications. These include:
Heat sink material for naval, ground-based and aerospace radar
Nickel-Gold plated external power amplifiers
5G mobile internet network

Molybdenum copper heat sinks is a composite made from Mo and Cu, Similar to W-Cu, CTE of Mo-Cu can also be tailored by adjusting the composition. But Mo-Cu is much lighter than W-Cu, so that it is more suitable for aeronautic and astronautic applications.
