a silver-white alloy, tough and difficult, but malleable and ductile, and very permanent floating around. It has nickel, copper, and zinc in varying proportions, and had been initially made of old copper slag at Henneberg. A small amount of iron can be included with make it whiter and more difficult. It is really identical using the Chinese alloy packfong. It had been formerly much employed for tableware, knife handles, structures, cases, bearings of equipment, etc., but is today mostly superseded by other white alloys.
