Nickel electroplating is a process of depositing nickel on a metal part. Nickel provides a strong, durable and malleable coating, with excellent corrosion resistance but does not provide Galvanic protection for most applications.
Nickel plating efficiency is very high, which means the “Throwing Power” is low. Deep recesses are hard to cover. For parts with deep recesses or surface variations, please look at Electroless Nickel Plating.
Nickel deposit are very hard ranging from 300 HV to 700 HV depending on the plating bath type and process conditions.
Nickel Thickness specifications usually range from 0.0001” to 0.002” depending on service conditions and the number of different types Nickel deposits required.
Corrosion resistance from nickel plating is due to the formation of a protective, oxide surface. Corrosion testing requires either Neutral Salt Spray or Corrosion Accelerated Salt Spray testing.
Types of Nickel Finishes:
Sulfamate Nickel – Engineering Nickel Deposit
Finish either Dull or Bright
Dull finish is a pure nickle deposit with no Organic additives
Bright deposit will require some organic additives
