Tungsten Nickel Iron alloys (~18.8g/cm3) are made of tungsten based
two phase composites with Ni, Fe as additions to form a ductile
matrix. Tungsten Nickel Iron alloys has good machining properties,
excellent radiation resistance, lower expansion coefficient, high
strength and modulus of elasticity, which make them extensively
used in radiation protection and guidance, balance weights,
security and defense etc.
Tungsten Nickel Iron Alloy Property
− High Density:Max as 18.8 g/cm3
− High Strength:Tensile strength as 700-1000 MPa.
− Excellent Radiation Protection:Tungsten alloy is 1.7 times than
Lead in radiation protection capability with same thickness.
− The Coefficient of Thermal Conductivity: The thermal conductivity
coefficient of tungsten alloy is 5 times of die steel.
− Small Thermal Expansion Coefficient: Tungsten thermal expansion
coefficient is 4~6×10-6/℃, only iron or steel 1/2-1/3.
− Good Plasticity, Machining and Welding Capability.
− Compared with lead toxicity, tungsten alloy is zero damage of
environment. Radiation detectors made by tungsten alloy has no harm
to human body.
− Compared with tungsten nickel copper alloy, tungsten nickel iron
alloy has ferromagnetic property, and the mechanical properties,
processing properties are better than tungsten copper nickel alloy.
