Nickel BK is a specially modified nickel bath which gives a thin black deposit. It is typically used for decorative finishes. Deposits of Nickel BK can be post treated in clear lacquer to further enhance corrosion resistance. Nickel BK can be used in rack and barrel applications.
The Nickel 5200 process has been developed to produce fully bright, highly levelled, ductile nickel deposits. The process can be used for rack or barrel plating.
