Abstract: The self-cure function was realized through making a series of experiments with the self-cure function and study on the mode of making the copper cube fiber. As it tumed out that it is very difficult to obtain the self-cure function by way of prefabricating and presubmerging the red copper cube fiber made by troditional drawing, but the self-cure function can be acquired primarily by prefabricating and presubmerging the brass cube fiber made by electroforming.
