High quality W-Cu alloy plate heavy gravity tungsten copper alloy plate

We mainly produce,develop and sell Tungsten and Molybdenum  plates ,sheets,foils,strips and boats,crucibles,vacuum furances and their subassemblies,sputtering targets,deep processing products ect, and Tantalum,Niobium,Titanium,Nickel,Zirconium,Chromium ect.other rare metals.The products are widely used in rare-earth,vacuum furance,glass fiber,industrial ceramic,chemical petroleum,aerospace ect,industries.   

Tungsten copper sheet are very popular used as EDM electrode. This material has both tungsten and copper's characters, for example: copper is good for electrical conductivity, tungsten is good for the hardness. Tungsten copper sheet for EDM is made by vacuum infiltration technology, which has very good physical and mechanical properties.

 WCu is easy to machine, Is extremely Dimensionally stable and has a high thermal conductivity.The coefficient of expansion is minimized.

Feature of different composition

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

Application

Copper tungsten alloy is used in a product or part requires high heat resistance, low thermal expansion and high electrical or thermal conductivity. Tungsten copper is used to fabricate 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 by copper tungsten alloy. The alloy is also made into sheet metal, tubing and plate metal. Copper tungsten alloy is used to make contacts for both high and medium voltage electrical devices, and for high speed steel devices and switches.
