Tungsten heavy alloys are made of tungsten-based with two-phase composites of NiFe or Cu as an addition to form a ductile matrix. Tungsten heavy alloys have good machining properties, excellent radiation resistance, lower expansion coefficient, high strength and modulus of elasticity which make it extensively used in military equipment, balance weights for submarine and vehicles, aircraft components, nuclear and medical shields, fishing and sport tackles.
