Tungsten heavy alloy tubes are suitable raw material for radiation protection, as tungsten heavy alloy tubes 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. Tungsten heavy alloy tubes can provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers. Tungsten alloy is non-toxic and are generally considered environmentally friendly, unlike lead or depleted uranium. Most commonly tungsten heavy alloy tubes are used as vial and syringe shielding.
