A series of corrosion tests of Fe-Ni-Cu alloys containing 50%, 60%, 70% and 90% Ni with varying Cu content 1.00-10.09% and a trace of carbon, were carried out by the dip method. The corrosion was examined in 10% aqueous solutions of HNO3, HCl and H2SO4 at 25° by measuring the loss in weight, and the extent of corrosion was expressed as mg/cm2 hour. The results were discussed by referring equilibrium diagram of the Fe-Ni-Cu system.
