A bucking kit is used on the backside of a metal rivet to counter the force of the hammering on the other side. It is a part of riveting process and could make the riveting easier when it works with the rivet gun. The product is usually made of tungsten alloys. The most outstanding property of the material is the high density of 17-19 g/cm³. Comparable densities are only reached by gold or platinum metals, which are considerably more expensive. Other exotic materials like rhenium, uranium or tantalum achieve these densities, but are either too difficult or expensive to obtain, or they have unsatisfactory mechanical characteristics.
Before welding techniques and bolted joints were developed, metal framed buildings and structures such as the Eiffel Tower, Shukhov Tower and the Sydney Harbor Bridge were generally held together by riveting. Also automobile chassis were riveted. Rivet bar is widely used in applications where light weight and high strength are critical, such as in an aircraft. Especially tungsten rivet bar, which is the most suitable material for repairing airplane, as its good hardness, wonderful machinability, high density but small volume. Many sheet-metal alloys are preferably not welded as deformation and modification of material properties can occur. Common but more exotic uses of rivet bars are to reinforce jeans and to produce the distinctive sound of a sizzle cymbal.
