Learn
A tungsten bucking bar works by mass: a dense bar backs the tail of a solid rivet so the shop head forms cleanly in a smaller, easier-to-place tool than steel. These guides cover what a bucking bar is, how to choose shape and weight for your rivet and access, how tungsten compares to steel, and a full size-and-weight chart.
Quality and custom work
Every bar is made from high-density tungsten alloy and built to consistent dimensions, with inspection and documentation to your specification on request. We also build custom and private-label bars to your drawing.
Built for buyers and builders
USA Tungsten supplies tungsten bucking bars to professional airframe shops and homebuilt-aircraft riveters. For the full line of tungsten products and heavy alloys, see our sister company TungstenParts.com.
