NFL 14-705 CuAl10Ni5Fe3 (UA10N)
Nickel Aluminium Bronze
CuAl10Ni5Fe3
A French AFNOR aerospace specification for Nickel Aluminium Bronze CuAl10Ni5Fe3. The alloy is one of the most popular specifications used by world wide aircraft manufacturers for landing gear bushings and bearings. It has extremely good wear resistance and anti galling properties. The alloy can be manufactured in several specifications including BS 2B 23, DTD 197A, BS2874 CA104, DIN 17665 and BS EN 12165 CW307G.
