Application Fields
These include counterweight components, radiation shielding components, among others. Tungsten alloy blocks are suitable for use in racing cars, aircraft, and sailboats—applications where strict constraints on the volume of counterweight components are required. Tungsten alloys exhibit excellent corrosion resistance and machinability. Tungsten is an environmentally friendly, wear-resistant, and high-hardness material. Due to its density being similar to that of gold, tungsten alloys can be used to manufacture weapon components, molds, and various counterweight components, such as counterweights for speedboats, vehicles, aircraft, helicopters, vessels, and tanks. Thanks to their superior properties—including high density, high melting point, high hardness, high wear resistance, exceptional tensile strength, and high-temperature resistance—tungsten alloys find widespread application across numerous fields. In particular, tungsten alloys possess outstanding radiation absorption capabilities and are now extensively utilized in the medical field.
