AMST 21014 class4 tungsten alloy rod has very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Due to their high density, tungsten alloys offer greater radiation shielding than lead and are non-toxic. It is electrically and thermal conductive and offer good corrosion resistance. It also has a low coefficient of expansion and has a high modulus of elasticity.
The properties of AMST 21014 class4 tungsten alloy rod are:
Alloy Type：97.5%WNiFe, 97.5%WNiCu
Density: 18.25~18.85g/cm3
Hardness Max: 35HRC
Elongation: 1~8%
Tensile Strength Max: 964MPa
Impact Toughness Max: 22J/cm2
Because of these unique properties, AMST 21014 class4 tungsten alloy rod is used extensively in military applications, balance weights, aircraft components, nuclear and medical shields, fishing and sport tackle, rocket components, tool vibration dampers, electrical contacts, etc.
