Abstract

Abstract Disclosed are improved lubricants particularly useful for forming metallic articles into desired sizes and shapes based upon operations enhanceable by lubricants. Typical specific working operations are cutting, sawing, grinding, shaping, planing, stamping, drawing, sanding, filing, milling, shearing, machining, and drilling. Preferred lubricant compositions are alkanol mixtures of predominantly normal alcohol and branched primary alcohol structures having predominantly from about 20 to about 34 carbon atoms per molecule, with or most preferably, without other alcohols containing secondary hydroxyl groups or unsaturation ranging from about 14 to about 50 carbon atoms per molecule. The preferred lubricant compositions are characterized by useful residual or film properties for protection of surfaces, particularly those freshly exposed through working when using the lubricants. Such properties are enhanced by the combination of polar and non-polar aspects of the preferred molecules.
