Why is german silver known as nickel silver ?

Answer 1

"The name German silver or nickel silver is misleading since it has no silver con­tent, but is an alloy of 60 per cent copper, 20 per cent nickel and 20 per cent zinc. It resembles silver but instead of the soft white colour it has a yellow-grey tinge.

German silver is used exten­sively in the hollow-ware and flatware industries as E.P.N.S. (electro-plated nickel silver), which is a nickel silver item with a plating of silver. Nickel silver is slightly more difficult to work for jewelry purpose, than copper and other metals, since it is a harder alloy. Again it is prone to tarnish on exposure to air and will turn the skin green with prolonged contact. "

why are you asking this in maths?

Answer 2

In 1823 a German competition was held to perfect the production process: the goal was to develop an alloy that possessed the closest visual similarity to silver. The brothers Henniger in Berlin and Ernst August Geitner in Schneeberg independently achieved this goal.
