Bronze C954 (Aluminum Bronze)
Bronze C954 – High-Strength Aluminum Bronze for Marine Hardware and Heavy Industrial Bearings
Bronze C954 aluminum bronze (91% Cu / 9% Al) delivers significantly higher strength than tin bronzes while maintaining excellent corrosion resistance in seawater and most industrial environments. Its high strength, wear resistance, and non-sparking characteristics make it indispensable for marine propellers, heavy industrial bearings, and bushings in severe service conditions.
Key Properties
- Tensile Strength: 586 MPa
- Yield Strength: 262 MPa
- Hardness: 159 HB
- Density: 7.45 g/cm³
- Non-Sparking: Yes — suitable for hazardous environments
- Standards: ASTM B505 / CDA 954
Common Applications
Ship propellers, marine bearings and bushings, pump impellers, valve seats, worm gears, aircraft landing gear bushings, and non-sparking tools for oil, gas, and mining environments.
