Copper Tungsten Properties

20 copper and 80 tungsten.

Copper tungsten properties.

The microstructure is therefore rather a metal matrix composite instead of a true alloy. Tungsten copper has unique material properties. 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 tungsten copper cuw or wcu is a mixture of copper and tungsten.

Tungsten or wolfram is a chemical element with the symbol w and atomic number 74. Heavy duty projection welding electrodes die facings for electro forming and electro forging also facings for upsetting of rivets and studs. Electrical conductivity iacs rockwell hardness ultimate strength psi cross breaking strength psi density gms cc. Very good thermal conductivity.

Mi tech tungsten metals copper tungsten alloys are commonly used in edm electrodes and other electrical and electrical thermal applications. Tungsten is a rare metal found naturally on earth almost exclusively combined with other elements in chemical compounds rather than alone. 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. As copper and tungsten are not mutually soluble the material is composed of distinct particles of one metal dispersed in a matrix of the other one.

Copper tungsten silver tungsten silver tungsten alloys contain between 25 50 silver and are mainly used for electrical contacts generally heavy duty devices subject to high current. The manufacturing process is to press the refractory sinter the pressed compact at a high temperature and infiltrate with copper or silver. Copper tungsten or wcu alloy also known as trade names elkonite is a composite matrix of tungsten and copper which combines the excellent properties of the elements such as heat resistance ablation resistance low thermal expansion and excellent thermal and electrical conductivity. A high level of temperature resistance is one of the most important advantages of tungsten while the copper content increases the electrical and thermal conductivity.

It was identified as a new element in 1781 and. Thus they are often used as electrical contacts particularly in high voltage applications.
