Car Tire Steel Cord Bead Wire Copper Coating Line

Steel Cord Brass Plating Line

1. Brief description

Brass plating is the application of a few µm thick zinc to the surface of copper - zinc alloy parts. During galvanic brass plating, the alloy usually contains 60-70% copper. The colour of the coating varies depending on the composition: from golden-yellow to grey-green. In the air, the coating fades quickly and varnish protection is required.

Brass is used to protect products from corrosion, to create an intermediate layer when nickel-plating or tinning steel parts. Brass coatings of steel parts are often used for decorative purposes.

Bead wire is the steel wire made of high-carbon steel typically plated with red copper or bronze. lt has a high strength, a good flexibility, a supreme fatique property and an excellent linearity. lt can be adhered to the rubber easily, and is mainly used in the tire bead as the framework material for reinforcement. it can be found widely applied in car tires, light truck tires, cargo truck tires, heavy equipment tires and plane tires.

The steel cord is a combination of several thin wires helping tires absorb shock while improving comfortability for passengers. lf the steel cord is made of highest-grade steel, the tire can withstand high level of stresses, thereby improving the stability and safety during driving.
