Wecome to visit Xi'an Kefeng Powder Metallurgy Co., Ltd! We are tungsten alloy leading manufacturer in China sine 1999, until today, we have 25 years production and exporting experiences. Company is certified ISO 9001-2015.
Below I'd like to introduce one product of ours, Copper-Tungsten alloy: Our Copper Tungsten meet or over ASTM B702 Standard. Products also meet RoSH.
Tungsten copper: Means an alloy composed of tungsten and copper, we usually do the material 15% to 45% copper and balance tungsten. The alloy is made by powder metallurgy method, Tungsten copper alloy uses high-quality tungsten powder and oxygen free copper powder, and applies isostatic pressing forming (high-temperature sintering) - copper infiltration to ensure product purity and accurate ratio, with fine structure and excellent performance.
Copper tungsten alloy combines the advantages of copper and tungsten:
A) With high strength,
B) High density,
C) High temperature resistance, arc erosion resistance.
D) Good conductivity and thermal conductivity,
E) Good processing performance.
Application:
1) Application in high hardness materials and thin electrode discharge machining.
2) Electrode materials, applied to high hardness materials and thin electrode discharge machining
3) A spot welding/butt welding electrode.
4) Contact materials: Arc contacts and vacuum contacts of high and medium voltage switches or circuit breakers, circuit board welding, and electrical contact points.
5) Guide material: various wire rolled steel, used for guiding and protecting materials.
