Industry Solutions
Marine & Offshore
Saltwater, wave action, and biological fouling create one of the harshest environments for metals. Our marine-grade bronzes, copper-nickel alloys, and brass products are engineered to survive and perform at sea.
Industry Overview
Marine and offshore environments subject metals to saltwater corrosion, biofouling, erosion, and extreme mechanical loads. Nickel aluminum bronze (C955, C630) and silicon bronze (C655) are the workhorses of marine hardware, while copper-nickel resists biofouling in seawater piping.
Key Requirements
Saltwater Corrosion Resistance
Alloys must resist pitting, crevice corrosion, and dezincification in chloride-rich seawater environments.
Biofouling Resistance
Copper-based alloys naturally resist barnacle, mussel, and algae attachment on submerged surfaces.
Impact & Fatigue Strength
Wave loading and vibration require alloys with high fatigue endurance limits and impact toughness.
Classification Society Approval
ABS, DNV, Lloyd's Register, and Bureau Veritas certifications for shipboard and offshore use.
Our Metals for Marine & Offshore
We supply the following metals and product forms to serve marine & offshore applications.
C955 nickel aluminum bronze for propellers and valves, C655 silicon bronze for fasteners and hardware, and C905/C907 tin bronze for pump bodies and fittings.
Copper-nickel alloys for seawater piping and heat exchangers. Copper sheet for hull sheathing and antifouling applications.
Naval brass and admiralty brass for condenser tubes, porthole frames, and decorative marine fittings with excellent seawater resistance.
