Tungsten bucking bars provide increased weight (density) to allow riveting in confined areas. The weight to size ratio provides a good kinetic energy transfer to expedite the rivet installation process.
Tungsten bucking bars are dense, durable tools commonly used in aircraft construction and sheet metal work. Due to their high density and hardness, tungsten bucking bars offer excellent back-up support during riveting or fastening, preventing metal distortion and ensuring strong, precise joints.
Tungsten bucking bars provide increased weight (density) to allow riveting in confined areas. The weight to size ratio provides a good kinetic energy transfer to expedite the rivet installation process. Tungsten bucking bars greatly reduce the vibration caused by driving rivets, thereby reducing or eliminating damage to one’s hands.
Advanced Refractory Metals has 20 years of experience manufacturing and distributing high-quality tungsten bucking bar with various shapes and dimensions.

Our tungsten bucking bars are mainly used on the backside of a metal rivet to counter the hammering force. They can also be used to absorb the force of rivet guns and to reduce the vibration of bucking.
Our tungsten bucking bars are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
