Copper Tungsten Properties

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.

Copper tungsten properties.

The physical and mechanical properties and melting point of tungsten copper material will be positively or oppositely affected by varying the amount of. The manufacturing process is to press the refractory sinter the pressed compact at a high temperature and infiltrate with copper or silver. 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. 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.

Electrical conductivity iacs rockwell hardness ultimate strength psi cross breaking strength psi density gms cc. The microstructure is therefore rather a metal matrix composite instead of a true alloy. It was identified as a new element in 1781 and. Tungsten copper has unique material properties.

Very good thermal conductivity. 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. Copper tungsten tungsten copper cuw or wcu is a mixture of copper and tungsten.

This refractory metal composite materials are a combination of tungsten combined with copper or silver. Tungsten or wolfram is a chemical element with the symbol w and atomic number 74. The name tungsten comes from the former swedish name for the tungstate mineral scheelite tungsten which means heavy stone. 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.

Thus they are often used as electrical contacts particularly in high voltage applications. Mi tech tungsten metals copper tungsten alloys are commonly used in edm electrodes and other electrical and electrical thermal applications.
