Tungsten Copper alloy Properties:
Tungsten copper alloy is a composite metal of tungsten and copper,
which combines many excellent characteristics of tungsten and
copper. Among them, tungsten has high melting point (tungsten
melting point is 3410 ℃, copper melting point is 1083 ℃) and high
density (tungsten density is 19.34g/cm3, copper density is
8.92g/cm3); Copper has excellent electrical and thermal
conductivity. Tungsten copper alloy (composition generally ranges
from wcu7 to wcu50) has uniform microstructure, high temperature
resistance, high strength, arc erosion resistance and high density;
With moderate conductivity and thermal conductivity, it is widely
used as military high-temperature resistant materials, electrical
alloys for high-voltage switches, EDM electrodes and
microelectronic materials. As parts and components, tungsten copper
alloy is widely used in aerospace, aviation, electronics, electric
power, metallurgy, machinery, sports equipment and other
industries.
No arc erosion: With the right mix of materials.
| |
By choosing the right mixture of tungsten and copper, we are able
to influence the product's arc erosion properties. At a tungsten
content of 80 %, we achieve the lowest arc erosion rates. Depending
on the voltage and current intensity as well as on economic
considerations, we can vary the tungsten content between 60 and 90
% to meet the exact needs of your application.

We also offer tungsten copper alloy rings, plates, spare parts,
etc..
