Tungsten Copper Foil Sheet

Tungsten copper refers to a pseudo-alloy material composed of tungsten and copper. The copper content is usually 10%-50%. Because metal copper can absorb a large amount of heat at extremely high temperatures and reduce the surface temperature of the material, this alloy is also called metal sweating material. . Tungsten Copper Foil Sheet is mainly made by powder metallurgy process, and has also undergone mechanical processing such as rolling, cutting and polishing. It has good ductility and flexibility, good high temperature strength, excellent electrical and thermal conductivity, good breaking performance, and high temperature resistance. Strong resistance, good electrical ablation resistance and high withstand voltage, it is very suitable for electrical contact materials and electrode processing materials. For example, in the electrical and electronic industry, Tungsten Copper Foil Sheet can be used as an electrical contact material for high-voltage switchgear and circuit breakers of different current types, which can increase the voltage level and power of the equipment.

1. High melting point and high temperature resistance: The CuW alloy has good thermal conductivity. Tungsten has a high melting point of about 3410 degrees Celsius. Therefore, tungsten copper foil has stable structure and performance under high temperature environments. During the operational lifetime of aerospace engines or rocket nozzles, extreme component temperatures are experienced with no deformation or melting of the components. Equipment continues to reliably function.

2. High hardness and high strength: Tungsten has high hardness and, because alloys are used, so does tungsten copper foil. Excellent wear resistance coupled with deformation resistance make tungsten copper foil ideal for precision mold processing along with mechanical part manufacturing with high stress and friction. The alloy's excellent hardness greatly lessens effective wear while prolonging service life.

3. Good thermal conductivity: WCu has good electrical and thermal conductivity which allows quick conduction of current or heat. In electronic package applications or use as resistance welding electrodes, tungsten copper foil reduces electrical energy losses while efficiently distributing equipment operational waste heat, ensuring stable equipment operation.

4. Low thermal expansion coefficient: The tungsten copper composites expand notches of thermal stress relative to the temperature changes during the microelectronic device packaging, thus maintaining the reliability and stability of the framework structure. Cracking, desoldering and many other complications due to thermal stress in microelectronic devices can be mitigated.

5. Arc ablation resistance: As electrical contacts foils in high voltage switches, circuit breakers, tungsten copper composites sustain arc eroding under the conditions of circuits being opened and closed Mesoscopic oscillations aligned with arc exposure retain the amount of material deviation while ensuring structural form stability.

6. Good machining performance: The advanced form transformation features defined by tungsten copper allows for the foils to be cut, ground and drilled into complex structures, meeting the standards of intricate piece manufacturing and fabrication simplistically.

The aerospace field has extremely high requirements for the accuracy and performance of parts. Tungsten copper foil can be used to manufacture and grind aerospace tools, as well as to process high-precision parts required in the aerospace field to ensure processing quality and accuracy. Widely used in medium, high voltage, medium and high current switching appliances, such as the protection circuit breaker contacts and other contacts and contacts of the transmission network. Tungsten copper contacts containing 15%-20% Cu can be used on circuit breakers with voltages up to 500,000 V or higher. Precise processing of key components such as cylinder block, cylinder head, crankshaft of the automobile engine to ensure the dimensional accuracy and surface finish of the parts, and improve the performance and reliability of the automobile. Ultra-precision processing of optical components such as optical lenses and prisms meets the extremely high requirements of the optical industry for component surface quality and accuracy.
