Special balls cover applications that do not fit into standard precision balls: barrel polishing, fine grinding, hollow balls for lightening or floats, magnetic balls, balls with functional coating (PTFE, epoxy, silvering, gilding, nickeling, chromeing) and colored balls. Each type meets specific specifications in terms of surface, mass, conductivity or chemical neutrality.
