Products Description
Copper Tungsten Screw Electrode is a kind of tungsten copper fastener made by combining high-purity tungsten powder with high-conductivity WCu Alloy Electrode Screw features low thermal expansion coefficient, high thermal conductivity, good current breaking performance, strong resistance to arc ablation, good high temperature resistance, low material loss, high conductivity, wear resistance and long service life. WCu Alloy Electrode Screw is the most commonly used electrical contact material and EDM electrode material, which plays the role of switching on and breaking current, directly affecting the reliability and service life of switches, electrical appliances and electrode processing equipment.
Features of Copper Tungsten Screw Electrode
1. High precision and thread compatibility: Thread precision reaches 6H level, tightly connected to equipment, reducing contact resistance.
2. High temperature resistance and arc resistance: The composite of tungsten matrix (melting point 3410 ° C) and copper phase (conductivity ≥ 85% IACS) can withstand high current and arc impact.
3. Lightweight and High Strength: The density is reduced compared to pure tungsten, and the tensile strength is increased, making it suitable for lightweight design.
applications of Copper Tungsten Screw Electrode
1. Copper tungsten screw electrodes are used for welding microelectronic devices and precision instruments to ensure the accuracy and stability of solder joints.
2. Copper tungsten screw electrodes, as screw electrodes in automated welding systems, have an extended lifespan and reduced replacement frequency.
3. Copper tungsten screw electrodes are used for welding missile and rocket engine components, meeting the requirements of high precision and reliability.
