Tungsten-nickel-iron alloy can be simply understood as an alloy with tungsten as the main raw material and nickel, iron, and copper as auxiliary raw materials, and the ratio of adding nickel-iron is generally 7:3 or 1:1. It finds extensive applications in aerospace, defense, and medical industries, where high-density materials are required for balancing, shielding, and radiation protection purposes.
Tungsten Nickel Iron Alloy exhibits outstanding machinability, allowing for precise shaping and fabrication of intricate components. Its versatility and reliability make it a preferred choice for demanding engineering and design challenges where density and durability are paramount.
Tungsten alloy rods, balls, plates, and other shapes are all available. We also do customization.
Properties of Tungsten Nickel Iron Alloy（W-Ni-Fe Alloy）
- Tungsten-nickel-iron alloy has a higher density :16.5-18.75g/cm³,
- Strength: tensile strength of 700-1000Mpa,
- Thermal conductivity: 5 times of die steel,
- Smaller linear expansion coefficient:only 1/2-1/3 of iron or steel,
- Good electrical conductivity and plasticity,
- Excellent weldability and machining performance.
Applications
- Aerospace:Used in aerospace components such as balance weights, vibration dampers, and counterweights for aircraft and spacecraft due to their high density and mechanical strength.
- Defense:Employed in armor-piercing projectiles, kinetic energy penetrators, and radiation shielding materials for military vehicles and equipment due to its density and ability to withstand high-impact forces.
- Medical:Utilized in medical devices such as collimators, radiation shields, and gamma-ray collimators for radiation therapy and diagnostic imaging applications due to their ability to attenuate radiation.
- Nuclear Industry: Found in nuclear shielding, reactor components, and radiation containment systems due to its high density and resistance to radiation damage.
- Precision Instrumentation: Used in precision instruments such as gyroscopes, inertial navigation systems, and precision balance scales for their density and stability in critical applications.
- Automotive:Employed in automotive applications such as crankshaft counterweights, balancing weights, and ballasts for race cars and high-performance vehicles due to its ability to optimize weight distribution and reduce vibrations.
- Sports Equipment: Found in sports equipment such as golf club heads, fishing weights, and bicycle components for its ability to provide precise weight distribution and improve performance.
Preparation Method of Tungsten Nickel Iron Alloy
Raw materials: ammonium tungstate, nickel nitrate, iron nitrate, concentrated nitric acid, etc.
Preparation Process:
1. Add the mixed solution of dispersant and ammonia to the ammonium tungstate solution under stirring conditions.
2. Add ferric nitrate and nickel nitrate to the above solution, stir it evenly, heat it in a 60℃ water bath for 10 minutes, then add concentrated nitric acid for a chemical co-precipitation reaction.
3. After the completion of the reaction, the precipitate is placed in a drying oven and calcined at 250°C for about 2 hours to obtain composite oxide powder.
4. After crushing the composite powder in a mortar and sieving with a 200-mesh sieve, the sieved powder is placed in a strong drainage venting furnace for low-temperature reduction (650°C-750°C) to obtain the tungsten-nickel-iron composite powder.
5. The composite powder is pressed with a steel mold under a pressure of 360 MPa to obtain a green compact.
6. The green compact is placed in an oxygen furnace at 1150°C-1350°C for 2h to sinter, and then the final product is made.
