1. n. cupronickel, nickel silver

GNU Webster's 1913

1. adj. (Chem.) a silver-white alloy, hard and tough, but malleable and ductile, and quite permanent in the air. It contains nickel, copper, and zinc in varying proportions, and was originally made from old copper slag at Henneberg. A small amount of iron is sometimes added to make it whiter and harder. It is essentially identical with the Chinese alloy packfong. It was formerly much used for tableware, knife handles, frames, cases, bearings of machinery, etc., but is now largely superseded by other white alloys.
2. n. (Chem.) See under German.
