Material Property

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.


Radiation protection and guidance: because of its high density (~18.8 g / cm3), and excellent X-ray, gamma ray absorptive capacity, excellent process ability, making Tungsten Nickel Iron alloy become ideal material for radiation therapy collimator and protection components.
