Alloy M25 (UNS C17300) offers the strength properties of Alloy 25 with the added benefit of being "free machining." Alloy M25 rod and wire contain a small amount of lead to provide an alloy tailored for automatic machining operations. Lead promotes formation of finely divided chips, thus extending cutting tool life.
