Tungsten Bucking Bars for Aircraft
A bucking bar is a piece of steel used to upset the driven head of the rivet. Bucking bars are made in a variety of sizes to fit various situations. Bucking bars must be handled carefully to prevent marring surfaces. When choosing a bucking bar to get into small places,choose one in which the center of gravity falls as near as possible over the rivet shank. Avoid using too light of a bucking bar,because this causes excessive deflection of the material being riveted. And in turn, it might cause marking of the outer skin by the rivet set. A bucking bar that is too heavy will cause a flattened driven head and might cause a loose manufactured head.
Therefore, choosing the right type of bucking bar is quite important. Chinatungsten Online is a professional manufacturer and supplier of tungsten bucking bar.

Steel bucking bars used in sheet metal assembly tasks are lack of ergonomic application principles. Four bucking bar interventions were evaluated and compared to a steel bucking bar. The interventions included a tungsten bucking bar. All interventions and the steel bar were evaluated for vibration transmitted to the hand and elbow, relative muscle activity of the flexor and extensor muscle groups of the forearms and usability. Vibration data collected at the hand revealed that the steel bucking bar transmitted the most vibration and the tungsten bucking bar transmitted the least. In terms of usability, participants perceived less exertion using the tungsten bucking bar and are more likely to recommend the tungsten bucking bars to others. Half of the participants ranked the tungsten bucking bar as their first choice of all the interventions tested.
