Ultra-high density & high temperature / strength stability
- High strength at extreme high temperatures (vacuum)
- Radiopaque to x-rays and other radiation
- Very high density of 19.3 gm/cc
- Excellent corrosion resistance
- Mechanical properties of tungsten studs
- Tungsten material datasheet
Tungsten studs are an ideal material for high temperature stability. Their extremely high melting point of 3420°C, makes tungsten studs useful for some of the hottest vacuum furnace environments. Another attribute of tungsten is its extreme high density. The high mass of tungsten studs make them radiopaque, allowing them to block radiation and show up well on x-rays – even better than lead. In addition, their high density also makes them ideal for balancing rotating parts. Beyond their high mass and temperature stability, tungsten studs are also very corrosion resistant.
Tungsten studs are usually made from tungsten alloys per ASTM B777, and range from 90% to 97% pure tungsten, alloyed with nickel and copper or nickel and iron. Studs can also be made from Commercially Pure (CP) Tungsten.
Applications
- The heat treating / furnace industry uses tungsten studs in high temperature vacuum furnaces due to tungstens great high temperature strength & stability.
- The oil & gas industry uses tungsten studs for radiation shielding properties to protect equipment used in oil and gas detection, as well as down hole logging for density and ability to withstand intense hydrostatic pressure
- Tungsten studs also play a role in the medical community for their low magnetic properties as well as their radiopaque properties.
- The aerospace industry depends on the tungsten studs for their combination of high density and mechanical strength which allows them to reduce the physical size of components, offering greater control of weight distribution for propellers, inertial systems and fluid control systems to name a few.
