Tungsten rod is a commonly used industrial material, usually made of pure tungsten or tungsten alloy. Tungsten rod is a widely used material that is commonly used in various high-temperature, high-pressure and corrosion-resistant environments. They are commonly used in applications such as manufacturing electrodes, heaters, arc guns, chemical reactors, and high-temperature furnaces. Commonly used materials: pure tungsten (W), tungsten alloy (tungsten-cobalt alloy (WCu), tungsten-copper alloy (WCu), tungsten-nickel-iron alloy). Tungsten rods are popular for their excellent high temperature performance, mechanical properties and corrosion resistance, as well as their wide range of applications in electronics, aerospace and other fields.
