What Is The Difference Between The Finish Screws?

There are many finish screws fasteners, such as galvanizing, nickel plating, vacuum plating, black coating, chrome plating, electrophoresis, etc., which are used on metal surfaces. So what is the difference between these? Today, Shenzhen Shi Shi Tong Screws introduces you to the difference between nickel plating, galvanizing and chrome plating:

a: chrome plating is mainly to improve the surface hardness, aesthetics, rust prevention. The chrome plating layer has good chemical stability and does not function in alkali, sulfide, nitric acid and most organic acids, but is soluble in hydrohalic acid (such as hydrochloric acid) and hot sulfuric acid. Because chromium does not change color, it can maintain its reflective ability for a long time and is superior to silver and nickel. The process is generally electroplated. finish screws

b: Nickel plating is mainly wear-resistant, anti-corrosion, anti-rust, and generally thinner processes are divided into electroplating and chemistry.

c: Zinc plating is mainly a surface treatment technology that coats the surface of metal, alloy or other materials with zinc to provide aesthetics and rust prevention. The zinc coating is also passivated, dyed or coated with a matting agent to significantly improve its protection and decorative properties. Zinc is a reactive metal that reacts with acids, so it is less resistant to corrosion and is the cheapest of nickel, zinc and chrome.
