Copper Tungsten Properties

Tungsten copper has unique material properties.

Copper tungsten properties.

It was identified as a new element in 1781 and. This refractory metal composite materials are a combination of tungsten combined with copper or silver. Mi tech tungsten metals copper tungsten alloys are commonly used in edm electrodes and other electrical and electrical thermal applications. Tungsten or wolfram is a chemical element with the symbol w and atomic number 74.

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. Very good thermal conductivity. Electrical conductivity iacs rockwell hardness ultimate strength psi cross breaking strength psi density gms cc. Tungsten is a rare metal found naturally on earth almost exclusively combined with other elements in chemical compounds rather than alone.

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. The microstructure is therefore rather a metal matrix composite instead of a true alloy. Heavy duty projection welding electrodes die facings for electro forming and electro forging also facings for upsetting of rivets and studs. 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.

Thus they are often used as electrical contacts particularly in high voltage applications. 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. 20 copper and 80 tungsten. 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. 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.
