COPPER-BASE/NONFERROUS
Types of Copper Base Alloy & Non-Ferrous Alloys
SILICON BRONZES
Silicon bronze alloys provide good resistance to corrosion in brine applications. They are commonly used for:
Pump and valve components
Fasteners
Marine hardware
ALUMINUM BRONZES
Aluminum bronzes offer:
Higher strength and corrosion resistant than other bronze alloys
Tarnish resistant
Corrosion resistant in sea water
Aluminum bronze alloys provide low oxidation rates at high temperatures and low reactivity with sulfurous compounds and other exhaust products of combustion. As such, they are commonly used for:
Plain bearings
Engine components (especially for sea-going ships)
Underwater fastenings in naval architecture
Ship propellers
Pump and valve components
TIN BRONZES
Tin bronzes provide:
Good mechanical resistance
Good corrosion resistance
Wear resistant
Applications for tin bronze alloys include:
Seal rings
Bushings
Bearings
Valve components
COPPER-NICKEL
Copper/nickel alloys offer:
Good cryogenic properties
High thermal conductivity without loss in ductility
Good corrosion resistance in marine applications
Antifouling properties
Low magnetic permeability
Copper/nickel alloys are ideal for:
Minesweeping equipment
Pump and valve components
Heavy-duty marine pump and piping applications
