Nikel Silver

Nickel silver, also called packfong, alpaca silver or German silver, is a family of alloys with a variable composition consisting of 50-60% copper, 15-30% zinc, and 10-30% nickel. The alloy turns out to be very similar to silver, but has better mechanical and corrosion resistance characteristics, and has been used by several manufacturers as a material for making caps (such as for Silvexa caps made by Pelikan) and referred to by several fictional names.
