On account of its permanence in air and inertness to oxidation, it is used in the smaller coins, for plating iron, brass, etc, for chemical apparatus, and in certain alloys, as german silver. It is magnetic, and is very frequently accompanied by cobalt, both being found in meteoric iron.

2. A small coin made of or containing nickel; especially, a five-cent piece. Nickel silver, an alloy of nickel, copper, and zinc; usually called german silver.
