Nickel Aluminum Bronze (Marine Grade)
Overview
C95800 is the premier marine-grade nickel aluminum bronze, meeting MIL-B-24480 specifications. It provides outstanding resistance to seawater corrosion, cavitation, and erosion — the standard alloy for naval and commercial marine applications.
As a C95800 nickel aluminum bronze (marine grade)supplier, Triton Bronze & Metals stocks continuous cast bronze in round bar, flat bar, plate, and more — all cut to length and shipped from US mills. Every order ships with a mill test report available upon request.
