Benefits of Various Copper Alloys and Typical Applications:

Pure Copper

High purity with excellent electrical and thermal properties
Mold liners for continuous and billet casting, high conductivity rotors, and cryogenic applications.

High Copper Alloys

Low-alloyed copper combining good conductivity with moderately high strength.
Machinery parts, such as brake drums and discs, in paper mills and carpet conveyors, and take-up rolls.

Lead Bronze and Brass

Nickel Silver

Moderate strength combined with corrosion resistance and excellent machinability.
Steam turbine parts, both new and replacement.
Packing and labyrinth rings.

Manganese Bronze/Yellow Brass

Aluminum Bronze

High Strength and excellent corrosion resistance.
Bronze gear blanks: worm gears and Hub gears.
Corrosion and anti-galling Components, such as bearing, gear, sealing, and valve and pump components.
Lubricated hinge ball bushings.

Copper-Nickel:

High seawater corrosion resistance and strength
Pump, valve, and bearing sleeve components especially in seawater environments, both commercial and Military.
