Product Description

Tungsten Copper (55W45Cu) Rod

Tungsten Copper Rod: These alloys are known for good thermal and electrical conductivity, low thermal expansion, and resistance to erosion from arcing. Thus, they are often used as electrical contacts, particularly in high voltage applications. Conforms to ASTM B702. 55W45Cu tungsten copper alloy is an alloy made of 55% tungsten and 45% copper composition. Preparation of alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. 55W45Cu tungsten copper alloy electrical materials: mainly divid into electrical contact materials and electrical processing materials.
