Copper Tungsten Properties
It was identified as a new element in 1781 and.
Copper tungsten properties. Copper tungsten tungsten copper cuw or wcu is a mixture of copper and tungsten. 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. 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. Mi tech tungsten metals copper tungsten alloys are commonly used in edm electrodes and other electrical and electrical thermal applications.
Copper infiltrated tungsten boasts such properties as high resistance to high temperature and arc erosion excellent thermal and electrical conductivity and a low cte coefficient of thermal. 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. The manufacturing process is to press the refractory sinter the pressed compact at a high temperature and infiltrate with copper or silver. The name tungsten comes from the former swedish name for the tungstate mineral scheelite tungsten which means heavy stone.
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. This refractory metal composite materials are a combination of tungsten combined with copper or silver. The physical and mechanical properties and melting point of tungsten copper material will be positively or oppositely affected by varying the amount of.

The microstructure is therefore rather a metal matrix composite instead of a true alloy. 20 copper and 80 tungsten. Tungsten is a rare metal found naturally on earth almost exclusively combined with other elements in chemical compounds rather than alone.
Thus they are often used as electrical contacts particularly in high voltage applications. Tungsten copper has unique material properties.
