Copper, brass and bronze wire

Thanks to up-to-date technology and equipment, production of wire in Valjaonica bakra Sevojno is flexible enough to satisfy market requirements regarding types of material, size assortment and fabrication quality.

All this enables sophisticated level of fabrication and drawing of finest wire sizes, (brass and bronze wire up to Φ0,05mm, and copper wire up to Φ0,1mm)

Quality and tolerances are as per EN or other world standards, as well as special requirements, (special mechanical properties, narrower technological characteristics, stricter tolerances, etc.), which are defined by special technical conditions.
