CDA 955, also known as UNS C95500 nickel aluminum bronze, is a high-strength copper alloy (Cu–Al–Fe–Ni) widely used for wear rings in centrifugal fire water pumps. In NFPA 20 / UL 448 / FM compliant pumps, the wearing ring is specified as bronze, and the impeller and shaft are typically AISI 316 stainless steel. The dissimilar-metal pairing of C95500 (stationary casing ring) against 316 stainless steel (rotating impeller) reduces galling risk, while the nickel addition improves resistance to seawater corrosion and erosion-corrosion in the high-turbulence region near the ring. With tensile strength of 620–760 MPa and hardness of 170–200 HB, C95500 offers a balance of strength, corrosion resistance, and machinability suited to both fresh- and saline-water fire pump service.
Flipper Arm Pivot Bushings are critical components in container crane spreaders, supporting high-load and impact-prone flipper mechanisms. CuAl10Fe3 and CuAl10Ni5Fe5 aluminum bronze, with optional graphite plugs, provide excellent strength, wear resistance, and self-lubricating performance.
