钨的密度大,是铅的1.7倍,具有良好的力学性能和工艺性能,是小型飞机、赛车平衡配重用的最好材料,可使飞机、赛车平稳运行,不产生摇摆。在力矩给定的情况下,用钨作为平衡配重件,体积更小、距重心点更远些。飞机的轻量化要求空载轻、配重体积小,以减少燃料消耗。 Tungsten has a density of 1.7 times that of lead and has good mechanical properties and process properties. It is the best material for small aircraft and racing balance weights, enabling smooth operation of aircraft and racing cars without rocking. In the torque given case, with tungsten as a balance weight, smaller, farther from the center of gravity point. Lightweight aircraft requires no-load light weight small size to reduce fuel consumption.
