0.025mm 6N/7N High-purity Super Fine Insulated/Bare OCC Copper Wire for Audio
At present, the entire industry is facing the problem that it is difficult to directly confirm single crystal copper. But we can increase the basis for judging single crystal copper through specific production equipment and processes. For example, copper materials produced by vacuum single crystal melting furnaces can largely ensure that they have a single crystal structure. Because this kind of equipment can provide specific conditions for the growth of single crystal copper, which is conducive to the formation of columnar crystals and the reduction of grain boundaries.
