Tuncop® 70W/30Cu is known as tungsten copper. It is a copper alloy produced by powder metallurgy and containing 70% tungsten. Tungsten has a very high resistance to arcing during welding. The high electrical conductivity of copper allows it to be used as an electrode. Tuncop® 70W/30Cu, used in tanning and welding applications, is a material known for its high temperature resistance, high toughness and excellent machinability. This material is used in many industrial applications, often in electrical appliances, such as wires and cables. In addition, Tuncop® 70W/30Cu is frequently used in applications where heat dissipation is needed, as it has high thermal conductivity. With its high performance and durability, Tuncop® 70W/30Cu helps businesses and manufacturers produce high-quality products.
You can find the properties of Tuncop® 70W/30Cu in the "Technical Details" tab. All mechanical and material properties of Tuncop® 70W/30Cu material are specified within this tab
Tuncop® 70W/30Cu material; as electrodes for butt and spot welding of stainless steels; For example, it is used in pot handle welding, as a high wear resistant electrode in plunge erosion process, spot welding of resistance wires and contact welding of electric motors.
