1 Products availableLeading Manufacturer, Supplier & Retailer of Oxygen Free Copper Rod, Copper Rods, Oxygen Free Continuous Cast Copper Rods, Copper Strips and Copper Flats.
Upward continuous casting technology provides top quality Oxygen Free copper wire rods with excellent conductivity, surface finish, ductility with homogenous grain structure and without harmful porosity. Oxygen Free High Conductivity (OFHC) copper rods are produced using LME Grade-A copper cathodes with 99.99% purity meeting international standards. These rods have a huge advantage when compared to traditionalElectrolytic Touch Pitch(ETP)copper rods.
