Born from a specific research, this coating of Tungsten Carbide, is extremely suitable for the slip drawing of brass coated steel for steel cord.
Applied and tested with success for several years, the coating offers good resistance to wear while maintaining its brightness unchanged with time.
With its special composition characteristics, it is suitable to perfectly withstand the chemical attacks from the aggressive emulsions.
This coating, as the UR427, due to the form and composition of the Tungsten Carbide Particles, offers a surface with a very low microporosity, obtaining very low average surface  roughness values.
Average surface roughness: Ra = .04/.06 u (metric).
