## Company
USA Tungsten supplies tungsten bucking bars to professional airframe shops and homebuilt-aircraft riveters. Tungsten alloy is about 2.5 times denser than steel, so a smaller bar delivers the same bucking mass with easier access and less hand fatigue. Every bar is quote-only with no online pricing; standard bars ship from stock and custom bars ship on a confirmed lead time. US-owned and operated; AS9100D, ISO 9001, and ITAR/DDTC. Submit the Request a Quote form for current pricing and lead time. Worn bars can be returned for a recovery credit through the Buyback program. For tungsten products beyond bucking bars, see sister company TungstenParts.com.
