Nickel plating deposits a layer of nickel on metal parts in an electrolytic bath, using electric current. Bright nickel gives a shiny decorative finish and is the base layer under decorative chrome; dull or semi-bright nickel is used for corrosion protection and wear. It suits steel, brass and copper parts such as fittings, handles, fasteners and electrical parts.

| Look | Bright possible | Semi-bright |
| Hardness | Lower | Higher, more after baking |
| Cost | Lower | Higher |
What to send

Questions
- Is nickel plating the same as chrome plating?
- No. Decorative chrome is a very thin layer on top of nickel; the nickel underneath gives the shine and protection.
- Does nickel plating prevent rust?
- Yes, if thick and free of pores. For outdoor steel parts, a copper or semi-bright nickel underlayer helps.
- Can threads be nickel plated?
- Yes, but plating adds thickness; ask for masking or allow for it on tight threads.
