Plating with nickel or chrome is a common way to protect metal and make it look better. Both methods are used in cars, household fittings, medical tools, and even aircraft parts. The coatings help the base material last longer and improve how it looks; however, while they serve the same purpose, nickel and chrome bring different strengths.
Nickel plating
Zinc nickel plating, which is available from specialists such as swmf.co.uk/surface-coatings/zinc-nickel-alloy-plating/, can use electricity or a chemical reaction. Bright nickel gives a shiny finish, while matte nickel is mainly used to stop rust. Electroless nickel, which uses chemicals instead of electricity, coats surfaces very evenly, even on small or hidden areas. It is very good at stopping corrosion, works well for soldering, and can even add magnetic qualities. Nickel can look bright or dull depending on the method. It is usually cheaper than chrome, especially for large batches, but it can have problems such as tiny holes and peeling.
Chrome plating
Chrome is often layered over nickel to give a shiny, mirror-like look. Decorative chrome is used on car trims and bathroom items, while tougher versions called hard or thin dense chrome are used when surfaces wear a lot, such as hydraulic parts or tools. Chrome is extremely hard and resists wear; however, the process uses hexavalent chromium, which is highly toxic and tightly controlled in the UK under REACH regulations.
Choosing between them
The choice depends on cost, looks, toughness, and safety rules. Nickel is often practical and affordable, while chrome gives a harder, brighter, and more durable finish.
