Power-on diffusion welding products-tungsten copper electrode

Performance Advantages

• Arc ablation resistance ：Tungsten's melting point is as high as 3422 ℃，The presence of copper can quickly transmit heat through good thermal conductivity, reducing local overheating. Therefore, tungsten copper electrodes can effectively resist ablation in arc discharge environments (such as welding and electric spark processing) and extend their service life.

• Excellent thermal conductivity ：Copper is an excellent conductor of electricity and heat. Although tungsten's electrical conductivity and thermal conductivity are not as high as copper, tungsten-copper composite materials still maintain a high conductivity and thermal conductivity, and can quickly conduct current and heat to avoid performance degradation or damage caused by overheating.

• High strength and hardness ：Compared with pure copper, the tungsten copper electrode has higher hardness and strength due to the addition of tungsten, which is not easy to deform during use, and can maintain stable shape and dimensional accuracy, especially in mechanical processing and clamping operations.

• Low coefficient of thermal expansion ：The thermal expansion coefficient of tungsten is low. After being combined with copper, the thermal expansion coefficient of tungsten copper material is between the two, and can be adjusted by adjusting the component ratio, which can achieve good thermal matching with other materials (such as ceramics and semiconductors) and reduce stress caused by temperature changes.
