The tungsten bucking bar is an indispensable professional tool in aircraft maintenance. It is typically used in conjunction with a rivet gun during the riveting process. When the rivet gun applies impact force to the rivet, the bucking bar provides a solid support surface and absorbs the impact energy, allowing the rivet to deform precisely and be securely fixed onto the materials being connected. This ensures the strength and precision of the riveting.

The manufacturing and maintenance of an aircraft require a large number of rivets to connect various components, such as the skin and framework. For example, the C919 aircraft has over a million rivets, while the Airbus A380 has more than five million rivets. Therefore, the choice of material for the bucking bar is critical to the quality of riveting and the safety of the aircraft.

Tungsten alloy is an ideal material for manufacturing bucking bars due to its high density, high strength, good ductility, and wear resistance. The tungsten bucking bar can withstand the enormous pressure during riveting, ensuring that the riveting points are smooth, secure, and highly precise. Additionally, it is resistant to wear and breakage, making it durable and meeting the high-performance standards required for aircraft maintenance tools.
