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.

Balance weights: It is widely used in automobile crankshaft counterweight, oil weight, security defense, precision optical instruments, due to the magnetic properties, high proportion of tungsten copper nickel alloy especially for in the aviation electron system.

Security and Defense：In modern wars, the main attack targets is tank armor, strong fortifications and combatants with armor protection, To gain lethal damage effect, the high performance materials with high density, deposit rate, strong penetration ability is necessary. Our company high performance tungsten alloy material can completely meet these requirements in national security and defense industry.

Nuclear energy parts: ATTL provides tungsten alloy for 3 + generation nuclear power plant cooling system of main pump. Because of its high density and excellent performance, inertia flywheel after precision machining is the most important component in the main pump of the cooling systems of nuclear power plant. It is the last method to ensure main pump system can continue working to avoid accidents.

Aviation parts: Tungsten nickel iron alloy has high strength and high erosion resistant ablative properties, widely used in aerospace components.
