Tungsten Copper Welding Button Contact

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).

    Feature Of Tungsten Copper Welding Button Contact

1. Joint Resistance and Arc Ablation. The combination of tungsten and copper in contacts creates a "false alloy" structure which sustains high levels of arc ablation due to the automatic energy recovery switches with high frequency interruptions. Furthermore, this structure reduces the chances of welding.

2. Dimensional Stability. Tungsten copper contacts possess low thermal expansion coefficients, enhanced dimensional stability, and maintain contact during temperature variations which aid in the avoidance of thermal stagnation. This feature makes them suitable for precision push button switches, improving operational accuracy and reliability.

3. Retention of surface smoothness. Contacts getting pressed, oscillated, or agitated for long periods need to have high-shard, dynamic, and mechanical wear resistance to maintain surface smoothness. These conditions are predominantly present in industrial control equipment employing contacts under multi-dimensional changing load.
 

    Application Of Tungsten Copper Welding Button Contact

Tungsten copper welding button contacts are used to connect contacts of power semiconductor devices. The low thermal expansion coefficient is matched with ceramics and semiconductor materials, reducing package cracks caused by thermal stress and improving heat dissipation efficiency. In scenarios such as household distribution boxes and industrial control cabinets, tungsten copper contacts quickly break the short-circuit current to protect the circuit safety, and their low thermal expansion characteristics avoid malfunctions caused by high-temperature deformation.
