Compared with some other common alloys, the advantages of tungsten copper alloy are mainly reflected in the following aspects:
1. Compared with nickel alloy
For example, nickel-chromium alloy has good high temperature resistance, but it is far inferior to tungsten copper alloy in thermal conductivity and electrical conductivity. Tungsten copper alloy combines the high melting point of tungsten and the high thermal conductivity and electrical conductivity of copper. It has obvious advantages in scenarios that require high thermal conductivity and high thermal stability, such as high-frequency electronic devices, high-power microwave devices and other fields.
2. Compared with tungsten alloy
- Pure tungsten and some tungsten alloys with high tungsten content are extremely difficult to process due to the high hardness and poor plasticity of tungsten. The addition of copper to tungsten copper alloy significantly improves the processing performance, so that it can be made into parts of complex shapes through a variety of processing methods, such as EDM, mechanical cutting, etc., which can be processed relatively smoothly.
- The main properties of pure tungsten alloys are concentrated in high hardness, high strength and high melting point, and the performance is relatively single. Tungsten copper alloy can flexibly adjust the performance of the alloy by adjusting the ratio of tungsten and copper. For example, increasing the copper content can enhance the electrical conductivity and thermal conductivity, while increasing the tungsten content can increase the hardness and high temperature resistance, so as to meet the diverse requirements of material performance in different application scenarios.
3. Compared with copper alloy
Higher high temperature resistance
- Ordinary copper alloys have relatively low melting points and are prone to softening and deformation in high temperature environments. Due to the high melting point of tungsten, tungsten copper alloy has much better high temperature resistance than ordinary copper alloys. It can maintain the stability of material performance at higher temperatures and can be used in high temperature working environments such as high temperature components of aerospace engines and electron beam welding guns.
Better arc erosion resistance
- In the fields of electrical switches, materials need to withstand frequent arc shocks. Copper alloys are prone to ablation and melting under the action of arcs, which affects service life and performance. Tungsten copper alloy has good arc erosion resistance and can maintain good surface integrity and performance after multiple arc actions, which improves the reliability and stability of electrical equipment.
