Tungsten material products usually contain a small percentage of other metals to improve or diversify its valuable properties. Due to high melting points and high strength, tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes, heating elements and shields in high-temperature vacuum furnaces, and turbine blades in generators and aircraft engines. Since tungsten is a very heavy element, the elimination of tungsten makes Co-based alloys increasingly viable in turbines for aircraft, where low density is especially important. After 1992, when Congress passed a tax credit, manufacturers invested in taller and more powerful designs.
