Ø40x1000mm tungsten alloy rod price is 1,280.00USD/KG on Jan. 22, 2020. The composition of the rod is 90WNIFE with density of about 17g/cm3. It has very high melting point and has a density twice that of steel and is more than 50% heavier than lead. Due to its high density, tungsten alloy rod offers greater radiation shielding than lead rod and is non-toxic. It is electrically and thermal conductive and offers good corrosion resistance. It also has a low coefficient of expansion and has a high modulus of elasticity.
