Aluminum Bronzes / Cast Aluminium Bronze Alloys are a combination of
high strength and corrosion resistance materials which makes them one of
most important engineering materials for highly stressed components that are
used in highly corrosive environments besides providing optimum wear and
abrasive resistance. Continuous Cast Aluminium Bronze Alloy is the form of Aluminium Bronze Alloys.

Type of Alloys
- Single-Phase Alpha Alloys - These have a good ductility and are
suitable for extensive cold working. CA102 is typical of this type -
Alloys containing 3% iron, such as CA106, are single phase up to over 9%
aluminium.
- The Duplex Alloys containing from 8% to 11% - aluminum usually with
additions of iron and nickel to give higher strengths
- Casting Alloys :
AB1/ CuAl10Fe3
AB2/ CuAl10Fe5Ni5/ CC 333G
- Wrought Alloy :
CA104/ CuAl10Fe5Ni5/ C63200
CA105/ CuAl10Fe3/ C63000
Indian Standard : IS 10569 1983
- The Copper Aluminium Silicon Bronzes have lower magnetic
permeability:
- Casting Alloys :
AB3/ CuAl6Si2Fe
- Wrought Alloy :
CA107/ CuAl6Si2/ C64200
Indian Standard : IS 10723 1983
