What is C95800 Marine Bronze?
C95800 is an alpha nickel aluminum bronze widely used for marine service, seawater hardware, pump parts, valve components, and propeller-related applications. It is often called C958 marine bronze, C95800 nickel aluminum bronze, or alpha nickel aluminum bronze.
The alloy is known for high strength, corrosion resistance in seawater, cavitation resistance, erosion resistance, and pressure tightness. It is a common material choice when marine bronze performance is required beyond standard bearing bronze.
