Tungsten Hex Nuts

Tungsten Hex Nuts

Tungsten hex nuts are known for their extreme high density; because of this unique attribute, they are often used for balancing rotating parts. Tungsten’s high mass also makes these nuts radiopaque. This allows tungsten hex nuts to block radiation and show up well on x-rays – even better than lead. Another unique attribute of tungsten is its extrmely high melting point of 3420°C. The high temperature stability of tungsten nuts make them ideal for some of the hottest vacuum furnace environments. Beyond their high mass and temperature stability, tungsten hex nuts are also very corrosion resistant.

Tungsten hex nuts 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.

Applications

· The aerospace industry depends on the tungsten nuts 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.

· The heat treating / furnace industry uses tungsten hex nuts in high temperature vacuum furnaces due to tungstens great high temperature strength & stability.

· The oil & gas industry uses tungsten nuts 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 hex nuts also play a role in the medical community for their low magnetic properties as well as their radiopaque properties.
