Founded in the year 2000, Yizhi Changtong has been focusing only in manufacturing ultra-fine enameled copper wires, bare copper wire diameter from 0.011mm to 0.800mm. Our monthly productivity is up to 1000 tons, among which 60% of the orders are for wires of diameter 0.100mm and smaller. Besides the ordinary UEW and EIW wires, we are expanding our product lines to ultra-fine self-bonding wires, copper alloy wires and CCA wires as well.
