Black Iron Wire

All the black wires for copper plating are made high-quality low-carbon steel wires which are purchased from Baosteel Group Shanghai ergang Co.,Ltd. They both have good quality and attestation of honor. There will be no metamorphosing during the heat treatment or mechanical workout. Producible scope: the diameter is from Φ1.00mm to Φ3.00mm.


Product Fearures: fast oxidation removal, good conductibility,high tenacity and good tensile strength. It is the best wire metarial for copper plating and galvanizing.


Main Application: copper clad steel, galvanized Iron wire and so on.
