Mil T 21014D class1 tungsten alloy ball has very high melting point and has a density twice that of steel and is more than 50% heavier than lead. It also has a low coefficient of expansion and has a high modulus of elasticity. It is used where extreme hardness and wear resistance is required in such applications as ballizing, bearings, ball screws, valves and flowmeters.
The properties of Mil T 21014D class1 tungsten alloy ball are:
Matrix: 90% W
Density: 16.85~17.25g/cc
Hardness Rockwell Max: 32HRC
Ultimate Tensile Strength: 110 KSI
Yield Strength (0.2% offset): 75KSI
