Copper Tungsten Properties

The name tungsten comes from the former swedish name for the tungstate mineral scheelite tungsten which means heavy stone.

Copper tungsten properties.

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. Electrical conductivity iacs rockwell hardness ultimate strength psi cross breaking strength psi density gms cc. 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. Thus they are often used as electrical contacts particularly in high voltage applications.

Very good thermal conductivity. The manufacturing process is to press the refractory sinter the pressed compact at a high temperature and infiltrate with copper or silver. Tungsten copper has unique material properties. The microstructure is therefore rather a metal matrix composite instead of a true alloy.

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. 20 copper and 80 tungsten. Tungsten or wolfram is a chemical element with the symbol w and atomic number 74. 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. Copper tungsten tungsten copper cuw or wcu is a mixture of copper and tungsten. 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. 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.

This refractory metal composite materials are a combination of tungsten combined with copper or silver. 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.
