Ductile Nickel Undercoat


2001

Can anyone tell me what 'ductile nickel' is and why and when it should be specified on gold plated components? My application is an electrical contact that must survive for at least 28 days exposed to seawater. The component has a 4 micron coating of bright nickel and 2 microns of gold at the moment, however I have been told that the correct specification for the under coat is ductile nickel. I do not understand why, or what the advantages of changing would be. Can anyone help?

Utilizing a "duplex" nickel system, i.e. a dull, ductile nickel under a bright nickel layer, substantially enhances corrosion resistance. It's the process of choice for outdoor plating applications, e.g. automotive trim, etc.

Ductile Nickel can achieved by plating with a sulphamate type bath.

Ductile nickel has a special property. He don't break when the material plated have a compression force. The surface remains ok.
