Product Description


Tungsten copper heat sink is a component or an assembly which transfers heat generated within a solid material to a fluid medium, such as air or a liquid to prevent thermal damage. Tungsten copper electronic packaging is used as heat sink pieces and encapsulation shell.
Tungsten copper heat sinks are developed with unique features such as certain mechanical strength,
good electrical properties, thermal properties and chemical stability.

Application

As a copper tungsten material, it's a composite. So both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized.
The combination of these two materials results in thermal expansion characteristics similar to those of silicone carbide, aluminum oxide, and beryllium oxide, used as chips and substrates.


Our products include W, Mo, Ta, Nb, Re of refractory metal products(such as sheet, foil, tube, rod, wire, crucible, boat, target, heavy alloy) and cemented carbide products(such as blade, mould, roll, hammer, wheel lug).

At the present, we have owned a number of the world advanced level production lines. The Co has 98 staff members with high talents, of which there are more than 30 employees with medium or high level professional titles and ranks, product improvement to strengthen the strong to do a good job protection. Our partners all over the world, we have become the first choice of many customers in Europe and American. Through the unremitting efforts of all staff, we won the praise of customers.

Our tenet is: "with the service and sincerity in exchange for your trust and support, mutual benefit and reciprocity, create a win-win!
