在比较了国内外几种金基三层微异型复合线材加工方法的基础上，研究出一种新的加工方法，即采用一次爆炸复合，一次扩散焊（或钎焊）复合法，减径采用孔型轧机轧制，异型模拉拔，最后用12辊微轧机轧制定径，从而大大提高了加工工效，降低了加工的难度。
On the basis of comparing the processing methods of several gold-based three-layer micro-shaped composite wires at home and abroad, a new processing method is developed, that is, one explosion compounding, one diffusion welding (or brazing) composite method, Hole mill rolling, profiled drawing, and finally with 12-roll mill rolling diameter, thereby greatly improving the processing efficiency, reducing the difficulty of processing.
