较软的材料，如黄铜，更容易受到损伤，但是也更有延展性，因此它们实际上可以通过变形来最大限度减少缺陷。
Softer materials, such as brass, are more easily damaged, yet are also more malleable, so they can actually deform to minimize imperfections.
推荐用于所有金属，包括不锈钢，如铝，黄铜，铜软金属。
Recommended for all metals, including stainless steel and soft metals such as aluminum, brass and copper.
