Don't put the Silver bit in your searches – search on Nickel Sheet and Nickel Alloys .
Nickel Silver and German Silver were names invented by ornamental plateware makers in UK and Germany . Its main use was for the base of Silver plated table ware .
Almost pure Nickel sheet was also once used for specialist chemical process vessels but glass and stainless steel are now much more usual .

' Nickel Silver ' type alloys are very easy to cast by the lost wax process . Some at least of musical instrument keys are made this way quite commonly . You could do this yourself but there are several professional sources for lost wax castings including a small number who supply the Model Engineering trade .
