Tungsten Copper Rod

Features: W-Cu is the use of high purity tungsten powder characteristics and excellent high-purity copper powder metal plasticity, high electrical conductivity, etc., by isostatic pressing, high temperature sintering, melting refined copper infiltration process of composite materials. Breaking arc performance, good thermal conductivity, small thermal expansion, the high temperature softening, high strength, high density, high hardness.
Uses:
1. Resistance welding electrode: a combination of the advantages of tungsten and copper, high temperature resistance, arc erosion, high strength, heavy, electrical conductivity, thermal conductivity, and easy machining, and other characteristics with the sweat of cooling, as with the tungsten high hardness, high melting point, anti-adhesion characteristics, is often used to do a certain wear resistance, high temperature welding, welding electrodes.
2. EDM Electrode: tungsten steel for high temperature super-hard alloy die to be produced by electrical erosion, the common electrode wear big, slow, and the tungsten and copper corrosion, high speed, low loss rate, the exact electrode shape, excellent processing performance, to ensure the accuracy of parts to be machined greatly increased.
3. High-voltage discharge electrode: high-voltage vacuum discharge tube at work, contact material will be a few seconds of time in the zero temperature thousands of degrees Celsius, while the anti-ablation properties of tungsten and copper, high toughness, good electrical conductivity, thermal conductivity performance to the discharge tube to provide the necessary stability conditions.
4. Electronic Packaging Materials: Tungsten, low expansion characteristics of both, but also has high thermal conductivity properties of copper, the thermal expansion coefficient and thermal conductivity of conductive material can be adjusted to change the composition and, thus provides a convenient use of materials.
