The Advantages of High Density Tungsten Alloy for Radiation Shielding

High density tungsten alloy has become an essential material for a wide variety of applications. It has the highest melting point of any metal, and its high density is equaled only by gold, platinum, and a few other rare and expensive metals. Pure tungsten is quite brittle and difficult to be machined. The addition of elements such as nickel, copper, and iron, creates a family of materials with extremely useful properties. High density tungsten alloys are economically fabricated by powder metallurgy techniques and are routinely machined by conventional methods. Mechanical properties add tensile strength, ductility, hardness-compare favorably with common engineering materials such as steel. Twice as heavy as steel and more than 50% heavier than lead, high density tungsten alloys have found wide acceptance where a concentrated mass is required in a limited space for such applications as radiation shielding, and a large variety of other uses.
