Type Color Description
Phosphating Grey (Light, Dark)/Black Surface conversion processing based on zinc and manganese oxides, providing better corrosion and wear resistance, lubricant properties increase, allows deposition of other substances if required (oils, polymers, rubber, wax).
Nitriding Grey Surface hardening termochemical treatment, provided by a diffusion of nitrogen on the surface. Wear and abrasion resistance of balls are higly increased.
Burnishing Black Allowing to get bright black balls, with better corrosion resistance and surface finish.
Brass Plating Bright Yellow Electrolytic treatment used mainly for decorative applications. It makes easier the adherence of rubber on the surface of the metals.
Copper Plating Pink/Red It is used mainly to increase the electric conductivity of balls.
Gold Plating Bright Yellow Electrilytic treatment mainly used in the electronic field and for decorative applications.
Silver Plating Bright White Electrolytic treatment, improving corrosion resistance and surface finish. It is used even in the electrical and optical fields. It is protected by a passivation.
Nickel Plating Silver Grey (Even Glazed or Sanded) Galvanic processing allowing to get harder balls, with higher corrosion and wear resistance. It is used even for decorative applications.
Tin Plating Silver White (Bright/Dark) Electrolytic treatment allowing to improve corrosion resistance and electric conductivity of balls. It is used in electronic and foodstuff industry.
Chrome Plating Silver White (Bright/Dark) Improving surface finish and increasing the corrosion resistance. The surface can be bright or matte finish.
Chrome Passivation Dark Yellow Surface treatment allowing to increase the natural corrosion resistance of stainless steel by strengthening the oxide layer. With different compositions it can be applied even to brass, bronze, Al Ni, Ti, stellite, alloys.
Sealing Zinc Plating Grey/Blue Sealing compound zinc plating processing increasing corrosion resistance the corrosion resistace.
Black Zinc Plating Black Protective/decorative zinc plating process, it allows to obtain a bright and homogeneous surface finishing.
White Zinc Plating Silver Iridescent Electrolysis process used to increase corrosion resistance, it is particularly suitable even for decorative applications. They can be subjected even to Chromiting (iridescent color).
Yellow Zinc Plating Silver Yellow Standard Zinc Plating processing allowing to get a good corrosion resistance (better than white zinc plating).
