Tungsten Copper Welding Button Contact
Tungsten Copper Welding Button Contact Description
With the continuous upgrading of electrical products and the rapid development of the electronic industry and technology, various application fields have put forward higher requirements for the core component of electrical devices - electrical contact materials, and tungsten copper is the most commonly used, low cost and has The material of choice for superior performance. Tungsten Copper Welding Button Contact can meet the strict requirements of the material itself will not melt under the action of huge heat and Joule heat, good welding performance, strong mechanical wear resistance, and good electrical performance. And the spatter generated during the metal crushing process should not be too much, the arcing time should not be too long, and the contact resistance should be low and stable. Tungsten Copper Welding Button Contact can be produced and processed by vacuum infiltration and injection molding processes, each step of which will undergo strict quality control to obtain a specific microstructure and superior mechanical and chemical properties. Tungsten Copper Welding Button Contact is very suitable for application in circuit breakers, transfer switches, power distribution or other high-energy and high-temperature equipment (such as electrical thermostats and motor protectors).
