Able to withstand greater heat than molybdenum and other high-temperature metal, this chemically pure tungsten is ultra dense for use in high-heat parts in vacuum furnaces, heat shields, and radiation shields. It’s also useful where increases in voltage cause temperature spikes that other metal can’t handle. Chemically pure tungsten is 1.7 times denser than lead and can be used as an alternative to lead as a heat shield, radiation shield, or as a weight. Due to carrying a large amount of mass in a small area, tungsten is commonly used as a weight to balance aircraft rotor blades, turbines, and also as a vibration dampener. However, it is not as economical as lead. This tungsten won’t deform from exposure to high heat, giving it a longer life span than other metal. However, because it’s chemically pure, it’s harder to machine than more ductile tungsten alloys. Pure tungsten is resistant to water, acids, and solvents. It is not attacked by nitric, hydrofluoric, or sulfuric acid solutions. This material won’t corrode from chemicals.
