Tungsten Bolt Screw Nuts Tungsten Molybdenum Titanium Threaded Rod
1. Specifications of tungsten bolt screw:
Tungsten screws are usually used in equipment and machinery under high temperature and high pressure environment, such as aerospace, petrochemical, nuclear industry and other fields. Due to tungsten's high melting point and corrosion resistance, tungsten screws are able to maintain their strength and performance under extreme conditions. In addition, the tungsten screw also has a low coefficient of thermal expansion and excellent wear resistance, giving it excellent stability and longevity in high temperature environments.
