Another galvanizing process and action for the shackle surface - zinc-nickel plating

Zinc-nickel plating is the plating of Zinc and nickel on the surface of objects respectively to play the role of anti-corrosion, beautiful appearance and wear resistance.

  1. Better corrosion protection

Zinc-nickel plating can prevent surface corrosion, especially in a humid environment, zinc has good rust resistance, can resist the oxidation of the surface of the object, to prevent the surface of the object rust. The nickel layer of galvanized nickel can prevent the zinc layer from losing its anti-corrosion effect because of oxidation, so as to achieve better anti-corrosion effect.

  1. More beautiful surface

Zinc-nickel plating can improve the gloss of the surface of the object, make the surface of the object more smooth, and increase the beauty of the object. In many household goods, electrical appliances, etc., the application of galvanized nickel has been very extensive, because it can make items look more high-end and fashionable.

  1. Abrasion resistance

The zinc layer and nickel layer of zinc-nickel plating can make the surface of the object harder, thereby increasing the wear resistance of the object. In some mechanical equipment, automobiles, etc., galvanized nickel is also widely used, because it can increase the wear resistance of the surface of the object and improve the service life of the object.

  1. Electrolytic action

The zinc layer and nickel layer of zinc-nickel plating can form a battery and form a protective film on the surface of the object to prevent the surface of the object from losing its anti-corrosion effect because of oxidation. At the same time, this layer of protective film can also make the surface of the object harder and improve the wear resistance of the object.

  1. Environmental protection

The application of zinc-nickel plating can reduce environmental pollution because it can make the surface of the object more durable, reducing the number of times people need to replace because of the aging of the item, thus reducing environmental pollution. At the same time, the application of galvanized nickel can also reduce waste generation, thereby reducing environmental pollution.

The Difference between Haosail Mooring Swivel and Ordinary Swivel
Ordinary Swivel: It is made of two parts, a bolt similar to a D-ring and a D-ring, and then the two parts are connected together and a hex nut is welded on it. However, the hex nut is easy to rust and fall off. HAOSAIL Mooring Swivel: It is different from ordinary Swivel in that it is composed of three parts: Two D-rings and a Screw in the middle, the head of the Screw is thickened, the two D-rings are connected with the Screw, and then the D-rings and Screw are welded at the back bottom of it. It is true that the screw's head is not easy to fall off, and the surface is hot dip galv. We can do this production method, is much stronger.

Why malleable cast iron ≠ steel ??
Why malleable cast iron ≠ steel ?? Time to learn some knowledge as below: Malleable cast iron is another name for malleable cast iron. Malleable cast iron is called malleable cast iron in English and is pronounced as M (马). Its performance is close to that of steel, so people commonly call it malleable cast iron. Because it is cast iron, it is also called malleable iron. Malleable steel is a cast iron made by pouring molten iron with a certain chemical composition into a white blank and then annealing it. It has high strength, plasticity and impact toughness, and can partially replace carbon steel.
