CuAl9Ni3Fe2
CC331GStandard aluminum bronze casting alloy — 9% Al, lower Ni (3%) and Fe (2%) than CuAl10Ni5Fe4 (NAB). Good strength and corrosion resistance at lower cost than NAB. Used for valve bodies, pump casings, bearing bushings, and marine fittings where NAB-level performance is not required. UNS C95400 equivalent.
