Product Overview
What UNS C95500 Bronze Is
UNS C95500 is a nickel-aluminum bronze casting alloy containing copper with additions of approximately 10.5 to 11.5 percent aluminum, 3.0 to 5.5 percent nickel, and 3.0 to 5.0 percent iron. This composition produces a two-phase microstructure that can be heat treated to raise strength and hardness substantially above standard tin bronze, making C95500 suitable for heavily loaded marine and industrial components.
UNS C95500 Bronze Sand Casting
Sand casting is the primary method for larger C95500 components such as propeller blades, pump casings, and valve bodies, with mould design and pouring practice controlled to manage the higher shrinkage and grain structure characteristics of aluminum bronze.
UNS C95500 Bronze Investment Casting
Investment casting is offered for smaller, intricate C95500 components such as impeller vanes, gears, and bushings where close as-cast tolerance and finer surface finish reduce machining allowance on this harder alloy.
UNS C95500 Green Sand Casting
Green sand casting supports medium volume C95500 components where reusable pattern equipment provides competitive per-piece pricing for recurring valve and fitting production programs.
UNS C95500 Centrifugal Casting
Centrifugal casting produces cylindrical C95500 blanks such as bushings, bearing sleeves, and wear rings with directional solidification that improves density, an important factor for the heavy-load bearing applications this alloy is often specified for.
UNS C95500 Permanent Mold Casting
Permanent mold casting is applied to higher volume C95500 components where a reusable metal mould improves dimensional repeatability and surface finish for recurring bushing and fitting production runs.
UNS C95500 Resin Sand Shell Molding / Casting
Resin sand shell moulding is used for C95500 components requiring improved surface finish and dimensional accuracy over conventional sand casting, reducing machining stock on valve bodies and gear blanks.
Typical Products Cast in UNS C95500 Bronze
Cable Glands India casts UNS C95500 bronze into marine propellers and propeller hubs, pump impellers and casings, valve bodies and seats, bushings and bearing sleeves, gears and worm wheels, guide vanes, wear plates, and offshore and naval hardware machined to customer drawings from the as-cast blank.
Key Features

- CNC machining available on the same castings for finished components
- Batch-wise chemical composition and mechanical test certificates
Alloy Composition Control
Melt chemistry is verified by spectrometer analysis before pouring to confirm copper, aluminum, nickel, and iron content falls within the C95500 specification window, since these elements govern the two-phase structure responsible for the alloy strength and corrosion performance.
Heat Treatment for Strength and Hardness
C95500 castings can be heat treated to refine the microstructure and increase tensile strength and hardness significantly above the as-cast condition, and Cable Glands India can supply castings in as-cast or heat treated condition depending on the mechanical property requirement.
Corrosion Resistance in Marine Service
The aluminum and nickel content in C95500 forms a protective oxide layer that gives strong resistance to seawater corrosion and cavitation erosion, supporting its widespread use in propellers and marine pump components.
Wear and Load Bearing Performance
C95500 is specified for bushings, wear rings, and gears operating under heavy load because its combination of hardness and toughness resists galling and wear better than standard tin bronze in many service conditions.
Casting Process Selection by Component
Cable Glands India selects sand casting, investment casting, green sand casting, centrifugal casting, permanent mold casting, or resin sand shell casting for each C95500 order based on component geometry, wall thickness, production volume, and target unit cost.

Applications in Industry
Marine Propellers and Propulsion Components
C95500 nickel-aluminum bronze is widely used for ship propellers, propeller hubs, and propulsion system components due to its combination of strength and seawater corrosion resistance.
Pumps and Valves for Corrosive Service
Pump impellers, casings, and valve bodies handling seawater or corrosive process fluids are cast in C95500 for long service life under demanding conditions.
Heavy-Duty Bushings and Gears
Bushings, wear rings, and gears operating under high load in marine and industrial machinery use C95500 for its wear resistance and load-bearing capacity.
Offshore and Naval Hardware
Offshore platform hardware and naval equipment components are specified in C95500 where mechanical strength must be combined with long-term corrosion resistance in marine atmospheres.
Manufacturing Process
Production begins with melt preparation in induction furnaces, where copper, aluminum, nickel, and iron are charged and alloyed to the C95500 specification, verified by spectrometer analysis before pouring. Depending on component size, tolerance, and volume, castings are produced by sand casting, investment casting, green sand casting, centrifugal casting, permanent mold casting, or resin sand shell casting, then fettled to remove gates, risers, and flash. Components requiring higher strength are heat treated before proceeding to CNC machining, where flange faces, bores, and critical surfaces are finished to drawing tolerance. Finished components are cleaned, dimensionally inspected, and packed for dispatch with accompanying material and mechanical test certification.
