The black-oxide finish on these taps retains lubricants to improve the taps' wear resistance and chip flow. Black-oxide taps should only be used on ferrous metals. These taps are made from powdered metal, which has a uniform microstructure and grain distribution that gives the material a similar strength as carbide. Powdered-metal taps are tougher and less likely to break than cobalt and high-speed steel taps. They are used for tapping highly abrasive materials such as high-silicon aluminum.
