Tungsten heavy alloy

Tungsten heavy alloy is a suitable raw material for radiation protection, as its combination of radiographic density (more than 60% denser than lead), good mechanical strength, and low thermal expansion, good corrosion resistance, high radiation absorption (superior to lead), simplified life cycle and high strength. It can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Besides, compared with lead or depleted uranium in the past, tungsten heavy alloy is more acceptable in this case, for they are Pb-free and non-toxic.

Balance weight has been used to deaden vibration in applications such as the pilot's stick and in riveting tooling. The same principle is used to increase passenger comfort by reducing vibration within the body of the aircraft,  this is particularly valuable in turboprops and helicopters.
