Naval brass C4430 (UNS C44300) is a high-performance copper-zinc-tin alloy that is widely used in shipbuilding and offshore engineering due to its excellent seawater corrosion resistance. The material's corrosion resistance is significantly enhanced by the addition of tin (Sn), while maintaining good mechanical and processing characteristics.
Key points of the production process
Precision melting: vacuum melting technology is adopted to strictly control the distribution uniformity of tin elements.
Hot + Cold Rolling: Optimise the grain structure and improve the strength of the material through multi-pass rolling.
Annealing treatment: eliminate internal stress, improve plasticity and corrosion resistance.
Surface treatment: optional polishing or passivation to further enhance corrosion resistance.
Core Benefits
Excellent seawater corrosion resistance: the inclusion of tin significantly improves resistance to dezincification and pitting.
Combination of high strength and good plasticity: suitable for high loads and dynamic conditions.
Excellent machinability: easy to cut, weld and cold form.
Long life and low maintenance: excellent durability in the marine environment.
Typical industrial applications
Shipbuilding: seawater piping systems, condenser tubes, propeller bushings and other key components.
Offshore engineering: structural parts of offshore platforms, seawater pumps and valves, heat exchanger components.
Chemical equipment: corrosion-resistant pump bodies, flanges, heat exchanger tubes.
Power industry: power plant condenser tube, seawater cooling system.
