摘要: A method of manufacturing an improved conductor wire, especially for use as wiring in audio/video devices is disclosed. The consists copper having a high purity at least 99.9 wt. %. High starting material formed rod which then heat treated temperature the range 400° C. to 700° 1 minute 24 hours. cold worked with reduction area 65%. This provides electrical wire avoids irregularities electron density and thereby eliminates phase differences frequency signal, such audio or video passing through obtain clear transmission reproduction sound image. invention increases residual resistance ratio 179 by 20% compared conventional not according invention. Finally, quality control method, expected characteristics manufactured can be evaluated determining wire.
