Cuprime Material Co. uses superior electrolytic copper cathodes to manufacture the high quality and highly purified 8m/m copper nugget. And our production manufacturing process has undergone many upgrades as well as the self-enhancement efforts from our R&Ds. Our product quality has reached the optimum characteristics like high elongation rate, low yield strength, high proportion and low copper powder quantity, and perfect to be used in various applications such as wiring conductor, signal transmission, copper angles, special wiring and super fine enameled wire, thus, we can provide for the uses by the high-quality electric wiring and cable plants with origin of both domestic and foreign.

Our company brought in the wire drawer machines used by large factories at Germany and Japan to manufacture bare copper wires with specifications below 3.2mm and subsequently , we fulfill all customers’ quality requirements as opposed to various copper materials.
