Abstract: This alloy comprises by weight 5.5-8 % aluminum (Al), 0.3-1.5 % indium (In), 0.25-2.0 % tin (Sn),  0.05-1.0  %  palladium  (Pd), with or without  0.1-0.5  %  titanium  (Ti)  and  the  rest  being composed of copper and the other impurities. Aluminum,  palladium, indium and titanium generate good golden color and form  a  stable oxide film on  the  alloy  surface  so  as  to  improve  corrosion resistivity and  discolor  resistivity.  Tin  improves  mechanical properties by forming a stable oxide film and  controlling  golden color. Especially, titanium makes Cu-Al alloy crystal  very  fine. This copper alloy is used for  ornaments,  and  has  an  excellent corrosion resistance, mechanical properties and golden color.
