Copper Tungsten Properties

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

Copper tungsten properties. Very good thermal 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. The manufacturing process is to press the refractory sinter the pressed compact at a high temperature and infiltrate with copper or silver. 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. Tungsten is a rare metal found naturally on earth almost exclusively combined with other elements in chemical compounds rather than alone.

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

Heavy duty projection welding electrodes die facings for electro forming and electro forging also facings for upsetting of rivets and studs. 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. 20 copper and 80 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.

It was identified as a new element in 1781 and. 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.
