Corrosion-resistant tungsten alloy rings are high-density ring-shaped materials prepared using powder metallurgy, with tungsten (W) as the main component (typically 85%~98%), and the addition of nickel (Ni), iron (Fe), copper (Cu), or other alloying elements (such as chromium (Cr)). They belong to the category of high-density tungsten alloys. Their core advantage lies in their combination of high density and excellent corrosion resistance, making them suitable for harsh corrosive environments.
1. Performance of Corrosion-Resistant Tungsten Alloy Rings
High Density: Typically 16.5~18.8 g/cm3, far exceeding that of steel and lead, providing greater weight for the same volume.
Corrosion Resistance: The tungsten matrix easily forms a dense oxide film at room temperature, exhibiting good resistance to dilute acids, alkalis, salt solutions, and seawater. Specific alloying designs (such as WNiCu or the addition of Cr) can further enhance resistance to uniform and localized corrosion, exhibiting stable performance in chemical, marine, and corrosive environments.
Mechanical Properties: High tensile strength (typically 700~900 MPa), with a certain degree of plasticity and toughness, capable of withstanding high pressure, impact, and vibration; moderate hardness and good surface wear resistance.
Other Properties: Low coefficient of thermal expansion, good dimensional stability, high temperature resistance, radiation resistance, and precision machining capability.
2. Applications of Corrosion-Resistant Tungsten Alloy Rings
Petrochemical and Pump/Valve Systems: Used as sealing rings in rotating or reciprocating equipment, resisting corrosive media such as acids, alkalis, and salts, maintaining high-pressure sealing performance, and reducing leakage and maintenance.
Marine Engineering: Provides stable performance as sealing or structural rings in long-term corrosive environments such as seawater and salt spray.
Power Energy and Nuclear Industry: Used for sealing or shielding components in high-temperature, high-pressure steam or radioactive environments, providing both corrosion resistance and radiation protection.
Aerospace and other industries: Precision ring components for hydraulic systems, fuel pumps, or high-temperature and corrosive conditions, utilizing their stability and durability.
