Tungsten copper alloy is mainly a mixture of copper and tungsten. The melting points of tungsten and copper are very different, and the two phases are not miscible. It is a typical pseudo alloy. Because tungsten copper alloy has the high melting point of tungsten and the high conductivity of copper, at the same time, above 3000℃, copper will be evaporated and absorbed in large quantities, thereby reducing the surface temperature and electron emission of tungsten copper alloy. Therefore, tungsten copper alloy has the advantages of high conductivity, high strength and hardness, and arc ablation resistance, and is widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery and other fields.
Traditional processing technology of tungsten copper alloy materials
At present, there are three traditional processes for preparing tungsten copper alloy materials: high-temperature liquid phase sintering method, activated liquid phase sintering method, and vacuum sintering infiltration method.
Latest processing technology of tungsten copper alloy materials
With the development of tungsten copper alloy materials, in order to continue to fully maintain its excellent performance and solve the shortcomings of traditional processing technology, in recent years, many scholars have continuously studied the processing technology of alloy materials and developed a variety of processing technologies, such as: rapid directional solidification technology, in-situ reaction casting, metal injection molding, functional gradient method, fiber replacement particle method, arc melting method, fixed structure method, etc.
Matters needing attention in the application of tungsten copper alloy materials
(1) When using copper alloy materials, it is necessary to pay attention to that colloidal graphite must not be placed on the surface of tungsten copper wire, and if the temperature reaches above 1000 ℃, it must be avoided that the wire is mixed with iron, nickel, and carbon, and should be placed in a dry environment. However, even in a dry environment, the humidity of the environment must be maintained. The humidity must not exceed 65% of the ambient temperature, and it cannot be mixed with alkaline substances to avoid affecting the tungsten copper alloy material.
(2) The tungsten-copper alloy material needs to be cleaned and placed in a dry container after cleaning to avoid direct contact with air and improve its anti-oxidation performance.
(3) The ratio parameters of tungsten and copper are also important considerations and attention in the application of tungsten-copper alloy materials. They need to be reasonably set according to production and use requirements to achieve the expected application purpose.
