Materials / Bronze Alloys

Bronze Castings

Bronzes deliver corrosion resistance, low friction and high load capacity — essential in marine, hydraulic and bearing applications. Monmet supplies the full range of copper-base alloys to the standards named on your drawing or purchase order.

Quick answer

Bronze alloys deliver corrosion resistance, low friction and high load capacity for bearings, bushings, marine propellers and worm gears. Aluminum, manganese, tin and leaded bronze each suit a different service — from seawater exposure to embedded lubrication. Monmet supplies the full range of copper-base alloys to the standards on your drawing.

Bronze Alloys

Alloy Families

Aluminum bronze (propellers, pump impellers), manganese bronze (gears, marine), tin bronze (bearings), leaded bronze (bushings).

Properties

Properties vary by alloy. Excellent seawater corrosion resistance (nickel aluminum bronze), high wear resistance with embedded lubrication (leaded grades).

Processes

Sand cast, centrifugally cast (sleeves, rings) and continuous cast (bar and tube stock). Heat treatment of aluminum bronze available for property enhancement.

Frequently Asked Questions

Nickel aluminum bronze (NAB) is a common choice for marine propellers, pumps and valves in seawater, resisting impingement and biofouling.

Centrifugal casting produces dense, segregation-free tubular shapes with improved mechanical properties compared with static castings.
