PROBLEM TO BE SOLVED: To exhibit excellent lubricity in plastic working of metal, prevent seizure of a workpiece on a tool surface, prevent tool abrasion, and facilitate processing and workability. An object of the present invention is to provide a lubricant for metal working, which has a lubricity equal to or higher than that of a lubricant containing a black solid lubricant, even if the lubricant does not contain a black solid lubricant. SOLUTION: A metal plastic working lubricant containing a lubricant base oil, a highly basic alkaline earth metal organic acid salt, and carbohydrates. |
