CuAl10Ni5Fe4 (ALBA 180-3) is a high-grade aluminum bronze alloy containing nickel, iron, and aluminum. It is specifically developed for heavy-duty industrial, marine, and defense applications that require high mechanical strength, excellent corrosion resistance, and thermal stability.
Its compliance with aerospace and military standards such as BS B23A and DTD 197A ensures long-term reliability under harsh operating conditions.
The nickel addition enhances the tensile strength of CuAl alloys and significantly improves corrosion resistance in seawater environments. Its superior wear performance makes it an outstanding choice for friction-loaded and dynamic components.
Technical Advantages:
- High tensile and yield strength
- Excellent corrosion resistance in seawater, saline atmospheres, and chemical environments
- Dimensional stability under high temperature and high pressure
- Improved friction and impact resistance due to nickel addition
- Long-lasting resistance against wear and erosion
- High suitability for welding and machining operations
Main Application Areas:
Marine Industry: Ship propeller shafts, underwater fittings, valves, pump housings
Defense & Aerospace: High-strength connection systems, flight structural components, naval defense systems
Petrochemical & Energy: Valves and flanges exposed to high pressure and corrosive media
Machinery & Heavy Industry: Sliding bearings, bushings, gears, coupling systems
Heat & Friction Applications: Components requiring thermal expansion control, friction-loaded bearing systems
Quality Assurance and Standards:
The CuAl10Ni5Fe4 alloy is fully compliant with BS B23A and DTD 197A, recognized British aerospace and defense standards.
All products are supplied with chemical analysis reports, mechanical test certifications, and full traceability documentation.
