Tungsten Copper Alloy 

 

 Applications of Copper Tungsten Composites WCu Alloy) The manufacturing process of WCu alloy is to press the refractory (tungsten or tungsten carbide), sinter the pressed compact at a high temperature, and infiltrate with copper. All of this is done under very closely controlled conditions. The mechanical and physical properties of WCu alloy vary with composition. The thermal and electrical conductivity increase with the amount of copper, while the hardness, strength, and resistance to mechanical wear increase with the amount of tungsten or tungsten carbide. The application determines the material choice.

 

Resistance Welding The high physical and mechanical properties, as well as the thermal and electrical conductivity, of refractory metal composites make WCu alloy very suitable for die inserts and electrode facings, flash and butt welding dies, and hot upsetting. They can also solve heat balance problems.

Heat Sinks The CuW75 tungsten copper alloy is used extensively in thermal mounting plates, chip carriers, flanges, and frames for high-power electronic devices. As a copper tungsten material, it's a composite, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be utilized. The combination of these two materials results in thermal expansion characteristics similar to those of silicone carbide, aluminum oxide, and beryllium oxide, used as chips and substrates.

 

Electrical Contacts The CuW75 materials can be also used in oil-filled devices, air and gas circuit breakers, contactors, and high voltage switch gear. Some common applications are: arcing contacts and plates arc runners current carrying members blade facings All of our Tungsten Copper alloys are produced by the press, sinter, and infiltrate process. Each manufacturing step, including the basic powder, is closely controlled, monitored, and signed off on by Quality Assurance. After completion, all manufactured lots are checked for conductivity, density, and hardness prior to shipping. This information is recorded and kept on file, and also accompanies the parts or materials when requested. EDM and ECM WCu alloys are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. All material is manufactured by the press, sinter, and infiltrate process. Virgin powders are used, resulting in a consistent homogeneous material giving high and even burning rates. Copper tungsten is used in plunger/sinker applications where intricate definition is required, especially in tungsten carbide.   Specifications of WCu Alloy:
