copper tungsten thread electrode is used when a product or part needs to have a high heat resistance, low thermal expansion and high electrical or thermal conductivity. tungsten copper rod supplier is used to make engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts are all made out of tungsten copper alloy. The alloy is also made into sheet metal, tubing and plate metal. Tungsten copper alloy is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches.

CuW50 and CuW55 have the lowest Tungsten contents. They are both good switching and contact materials for oil filled devices. CuW55 is also used for arcing contacts in oil circuit breakers and arcing edges of selectors and switchblades in transformer tap changers.

CuW65 and CuW70 are used as contact materials in severe arcing applications including gas, oil and some air circuit breakers. They are also used for arcing edges on selectors and reversing switch blades.

CuW75 and CuW80 are used as contact materials under extreme arcing conditions. Applications include arcing contacts in gas and oil circuit breakers, contactors and transformer tap changers, arcing plates and arc runners in power switching equipment.

CuW85 and CuW90 have the highest Tungsten content. They are used as contact materials where resistance to contact welding, sticking and arc erosion are critical. They also provide satisfactory heat and current interruption capabilities. Typical applications are power vacuum switches and high power spark gap electrodes, etc

PLEASE BE NOTED THAT WE CAN PRODUCE THE TUNGSTEN COPPER ELECTRODE ACCORDING TO CUSTOMERS' DRAWING OR SAMPLES.

What's Tungsten Copper Alloy?
Tungsten copper alloy (Copper Tungsten Alloy, CuW, or WCu) is a pseudo-alloy 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. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine. Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.

Tungsten copper parts provided by us are all with these properties. The electrical and thermal properties of the alloy vary with different proportions. Copper increases the thermal conductivity, which plays a huge part when being used in circuit breakers. Electrical resistivity with an increase in the percentage of tungsten present in the alloy, ranging from 3.16 at 55% tungsten to 6.1 when the alloy contains 90% tungsten. An increase in tungsten leads to an increase in ultimate tensile strength up until the alloy reaches 80% tungsten and 20% copper with an ultimate tensile strength of 663 MPa. After this mixture of copper and tungsten, the ultimate tensile strength then begins to decrease fairly rapidly.
