Heavy Alloy® Parts

Heavy Alloy® is a sintered material created by adding metals such as nickel, copper and iron to tungsten and increasing the density. It is used in a wide range of fields due to its outstanding mechanical properties such as high density, high vibration damping performance and high Young's modulus, along with outstanding radiation shielding and heat resistance. Toshiba Materials uses Heavy Alloy® in collimator parts due to its outstanding radiation shielding, and produces a range of other Heavy Alloy® parts such as balancers due to its high density.
