1. There is no discoloration and dissolution on the plating after high-temperature aging; and the high-temperature aging conditions of 155℃ 16H, 170℃ 4H, 180℃ 2H, 200℃ 1H and so on can be arbitrarily selected.
2. The weldability is excellent; the ferrochrome soldering, wave soldering and reflow soldering can be arbitrarily satisfied.
3. The plating is bright, smooth, uniform and moist; and the binding force and continuity is good.
4. The mechanical properties can be privately customized, to ensure stable and reliable application in the different conditions.
