For our Loop Diamond Wire Saw, it could be used for cutting the hybrid materials, such as ceramic mixed with iron, when cutting, the iron chips will be adhered onto the diamond surface, but at the same time, the ceramic materials will carry off the iron chip, so the hybrid materials is ok. If cutting the pure metal, after cutting some distance, the iron will be adhered onto the diamond surface and stop the diamond further cutting, so it is not fit for the big area cutting, small area pure metal is ok.
