This Tungsten Heavy Alloy Bar is one of the main products of tungsten alloy and has a high density range, which is 50% higher than that of lead. Heavy tungsten alloy has the advantages of ray density (more than 60% of lead density), good machinability, good corrosion resistance, high radiation absorption (better than lead), simple life cycle and high strength, and is a suitable raw material for radiation protection. . In addition, the effect of material ratio and processing technology on performance has been carefully considered, it is not easy to chip and break, and it has good scalability.
Tungsten Heavy Alloy Bar application
