Abstract

A tarnish resistant alloy which may be used as a visual colour substitute for copper comprises:- <TABS:1085180/C6-C7/1> and has a chromaticity consisting of dominant wavelengths between 584 mm and 592 mm in a colour purity range between 18.5% and 30.2%. The alloy may be heat treated in an oxygen containing atmosphere at 400 DEG C. followed by slow cooling or at 600 DEG C. followed by water quenching to improve the tarnish resistance and colour thereof. missing page 110
