90WMoNiFe is a high-density tungsten alloy composed of tungsten (W), molybdenum (Mo), nickel (Ni), and iron (Fe), with the following advantages:
1. High Density
• The high-density characteristic of tungsten gives this alloy an extremely high density (approximately 17.1 g/cm³), making it suitable for applications requiring high density and small volume, such as aerospace, military, and radiation shielding.
2. Excellent Mechanical Properties
• The alloy has high strength and hardness, demonstrating good compressive strength and impact resistance in complex stress environments, which makes it ideal for high-stress mechanical components.
3. Good Machinability
• Although tungsten itself is difficult to machine, the composition optimization of 90WMoNiFe alloy improves its machinability, allowing it to be processed using conventional machining methods such as turning and milling.
4. High-Temperature Resistance
• The high melting points of tungsten and molybdenum (3410°C and 2623°C, respectively) give the alloy excellent high-temperature resistance, making it suitable for high-temperature applications like rocket nozzles and thermal field components.
5. Good Corrosion Resistance
• The addition of nickel and iron enhances the material’s resistance to corrosion, allowing it to remain stable in chemically corrosive environments.
6. High Radiation Absorption Capacity
• Thanks to tungsten's high density, the alloy provides excellent shielding against X-rays and gamma rays, making it widely used in medical and nuclear industries for radiation shielding materials.
7. Low Thermal Expansion Coefficient
• Tungsten’s low thermal expansion coefficient ensures minimal dimensional changes in high-temperature environments, maintaining precision and stability.
8. Environmentally Friendly and Non-Toxic
• Compared to traditional lead-based materials, the 90WMoNiFe alloy contains no toxic elements, making it more compliant with modern environmental and health standards.
By combining these attributes, the 90WMoNiFe tungsten alloy is an exceptional material suitable for a wide range of demanding applications.
