YUHONG GROUP - Differences between chrome, nickel and galvanised plating

Electroplating is the use of electrolysis in some metal surface plated with a thin layer of other metals or alloys, is the use of electrolysis to make the surface of the metal or other material parts attached to a layer of metal film of the process so as to play a role in preventing oxidation of the metal (such as rust and corrosion), to improve abrasion resistance, electrical conductivity, reflective, corrosion resistance (copper sulfate, etc.) and enhance the role of the aesthetics and so on.

Electroplating is divided into specific processes such as copper plating, gold plating, silver plating, chromium plating, nickel plating and zinc plating, with zinc plating, nickel plating and chromium plating being the most widely used in the manufacturing industry.

01-Galvanised

Definition: Zinc plating is a surface treatment technique to coat the surface of metals, alloys or other materials with a layer of zinc in order to provide a beautiful appearance and prevent rust.
Characteristics: Low cost, general corrosion protection, silver-white colour.
Application: Screws, circuit breakers, industrial supplies, etc.

02-Nickel Plating

Definition: The method of plating a layer of nickel on metal or some non-metal by electrolysis or chemical method is called nickel plating.
Characteristics: beautiful, can do decorative, high price, slightly complex process, the colour is silver white showing yellow.
Application: energy-saving lamp head, coins, hardware, etc.

03-Chrome Plating

Definition: Chromium is a bright white metal with a slight bluish tinge. The method of plating a layer of chromium on metal or certain non-metals by electrolytic or chemical methods is called chromium plating.
Characteristics: There are two kinds of chromium plating, the first is to play a decorative role, the appearance of bright, wear-resistant rubbing performance is better, the ability to prevent rust is not as good as zinc plating, better than oxidation; the second is to increase the hardness of the metal parts, abrasion resistance, etc., which is the functionality of the parts.
Application: Bright decorative parts on home appliances, electronics and other products, tools, taps, etc.
