Brass plating instead of copper plating is due to the high adhesion between brass and rubber. Copper and zinc are mainly divided into high copper (64. X%) and low copper (6 1. X%)。 At present, brass plating is the main production method of steel cord, and its adhesion effect depends on the adhesion between coating and steel. At present, the production process is copper plating first and then wire drawing. It may be a problem whether silylated coating can withstand abrasive drawing. Of course, there are also galvanized and copper-free coatings abroad.
