Product Details

tungsten copper High medium low voltage switch gear contact/load break switch contact/circuit breaker contact

Owing to the good performance of electrical conductivity, tungsten copper contact can be used as electrical contact material, The high electrical and thermal conductivity of copper are combined with the arc-resistant and non-welding properties of tungsten or their carbides to form an extensive series of compositions. Each is designed to give the best performance for your particular application.

We are able to influence the copper tungsten contacts’ arc erosion properties by choosing the right mixture of tungsten and copper. With tungsten content reaching at 80 %, we achieve the lowest arc erosion rates. Depending on the voltage and current intensity as well as on economic considerations, we can vary the tungsten content between 50 and 93 % to meet the exact needs of clients' application.
For switch contacts, we also have copper tungsten carbide contacts or CuWC contacts for your inquiry. With high density, high strength and hardness, arc wear resistance, copper tungsten carbide contacts is wildly used as the electrical contact and electrode too.

All of our materials are produced by the press, sinter, and infiltrate process.
Each manufacturing step, including the basic powder, is closely controlled, monitored, and signed off 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. You can use our tungsten copper switch contact without any worry.
