Details

Copper wire is made of electrolytic copper and usually annealed. Electrolytic copper is referred to as Cu-ETP and has a purity of at least 99.9%. Most copper wire has a circular cross-section and the thicker the wire, the smaller the resistance, increasing the amount of current that can be carried. All our copper wire products are produced according to EN 13601.
