Material Components : 70-90% Tungsten + 30-10% Copper

          Techniques: Copper Tungsten composites are fabricated from controlled  an                       porous tungsten that is vacuum infiltrated with molten copper.

          Virtue:

	- Excellent electrical conductivity combined with high arc resistance.
	- High thermal conductivity.
	- Low thermal expansion.
	- better physical and mechanical properties than other tungsten alloy.

           Applications: Copper Tungsten products are used in sealed cap for transistors sealing welder, contactor materials for high-voltage breakers, electrodes for spark processing, circuit breakers, Heat sinks in electronic devices, EDM electrode.

           We, Luoyang Achemetal Company Ltd, also supply Copper Tungsten rod, Copper Tungsten Plate, Copper Tungsten Tube, Copper Tungsten rings, Copper Tungsten electrode, Copper Tungsten finished parts. The largest size of our Copper Tungsten product is 150kgs and the smallest size is 10 grams only. We stock copper tungsten alloy as rod, bar, plate and wheel. Generally, delivery in 1 - 2 weeks.
