ABSTRACT:
Metal working operations, especially drawing, are facilitated by applying to the metal a composition which provides lubricity thereto and which melts within the range of about 30.degree.-100.degree. C. The composition comprises at least one ester of a carboxylic acid, with a carboxylic acid or derivative thereof, a phosphorus acid salt and an antioxidant being preferred optional ingredients. The composition may be applied in liquid from and solidifies on cooling to ambient and normal storage temperatures. Prior to application, the composition is preferably heated to a temperature higher than its melting temperature for ease of flow and uniform dispersion thereof onto the metal. In a preferred method of application, a reservoir is located beneath the composition applicator and composition is pumped therefrom to the applicator, preferably a roller coater, with excess composition being recirculated. Steam may be used both to heat the composition to melting point and purge the pump and circulation piping at the start and finish of each run.
