Copper-Nickel Alloys: Properties, Processing, Applications
extracting copper from it – a spell was cast on the ore by a 'nickel'. It was only red nickel pyrites (NiAs), for the veins of ore worked in seams also incorporated copper and iron sulphides as well as arsenides. In England, the term 'cupronickel' was used at the start of the 20th century for an alloy of 80% Cu and 20% Ni.
