Tungsten Copper Square Bar

Since Tungsten Copper Square Bar is made from Copper powder and high-grade Tungsten powder using an array of Copper, Tungsten, and electro-mechanical machining techniques, it is categorized as a refractory metal. Depending on actual demand and application, the copper additive may be changed.

Tungsten Copper Square Bars possess strength along with electrical and thermal conductivity, mechanical strength, endurance against arcs, fractures, high temperatures, and copper-wrought durability.

Demand for these materials comes from innovative industries which invented precision tools for the aerospace and military sectors, and for electronics, due to their useful properties as advanced conductive, anti-corrosive, high-temperature resistant materials. Comparatively low cost and high-performance tungsten copper electrodes, compared with traditional copper electrodes, intensify their use in industry.

1. High melting point and softening resistance: The melting point of tungsten is as high as 3422℃. The tungsten copper square rod can still maintain structural stability at high temperatures (such as above 2000℃). It is suitable for instantaneous high-temperature scenarios such as rocket nozzles and missile tail rudders.
2. High hardness and wear resistance: The higher the tungsten content (such as 80W20Cu), the hardness can reach more than 220HB, and the wear resistance is significantly better than copper alloys.
3. Anti-adhesion characteristics: high surface finish and is not easy to stick to metal workpieces. It is suitable for welding electrodes, molds and other scenarios where frequent contact is required.
4. Dimensional stability: low thermal expansion coefficient (7.0-7.5×10⁻⁶/K), small dimensional changes under temperature changes, and are suitable for high-precision fields such as aerospace and electronic packaging.

1. Used to manufacture high-temperature components of spacecraft, such as gas rudders in the flight direction of guided missiles, missile ends (head cones, nose cones), etc., to maintain stable performance in extreme environments.
2. In high-voltage vacuum discharge tubes, the ablation resistance and high conductivity of the tungsten copper square rod ensure that the contact material can still work stably when the temperature rises by thousands of degrees Celsius within a few seconds of zero.
3. Resistance butt welding material used in radio resistor factories to produce carbon film resistors and metal coating resistors, and the stable performance of tungsten copper square rods ensures welding quality.
4. Non-magnetic and highly biocompatible tungsten copper square rods can be used to manufacture precision components of medical equipment, such as collimators of X-ray equipment, positioning devices of radiotherapy equipment, etc.
