Copper Tungsten Mechanical Properties

20 copper and 80 tungsten.

Copper tungsten mechanical properties.

For example as the copper content gradually increases the electrical and thermal conductivity and thermal expansion exhibit a tendency of being stronger. Heavy duty projection welding electrodes die facings for electro forming and electro forging also facings for upsetting of rivets and studs. Copper tungsten is a good choice for a vacuum contact due to its low cost resistance to arc erosion good conductivity and resistance to mechanical wear and contact welding. Tungsten copper is frequently used as an electrode material in case that the typical copper contact materials e g.

The properties when machining. At the heart of the switching chamber wcu arcing contacts are exposed to extreme mechanical and thermal stresses. Machining the machining is carried out by carbide tools. Consisting of pure tungsten w powder suspended in a matrix of copper cu these alloys are readily machinable and known for good thermal and electrical conductivity low thermal expansion being non magnetic good performance under vacuum and resistance to erosion from arcing.

The physical and mechanical properties and melting point of tungsten copper material will be positively or oppositely affected by varying the amount of copper tungsten in the composite. Cuw is usually a contact for vacuum oil and gas systems. It is also used in construction and industrial machine. Tungsten copper heat sinks they are composites of tungsten and copper.

Most of copper element is used in manufacturing electrical and electronic equipments such as wirings and components. Mechanical properties of tungsten comprise of its density tensile strength viscosity vapor pressure. The manufacturing process of tungsten copper alloy is to press the refractory tungsten or tungsten carbide sinter the pressed compact at a high temperature and infiltrate with copper. Tungsten copper for sf 6 circuit breakers.

Tungsten and its alloys are used in high temperature applications like welding electrodes high temperature furnace etc. All of this is done under very closely controlled conditions. The mechanical and physical properties of tungsten copper alloy vary with composition.
