A number of oleochemicals have found application in the formulation of metal processing lubricants. Calcium palmitate can act as a gelling inhibitor for lubricants for non‐chip metal forming, and diglyceryl oleate and sodium oleyl sulphate have been employed in chipless forming and machining lubricants. Glyceryl monooleate has been used together with paraffin wax and xylene for forming aluminium sheets, and isopropyl oleate has been blended into lubricants for cold forming of metal. Lubrication in cold forming of steel and aluminium alloys has been promoted by the use of sodium stearate and phosphating processes. Stearic acid has also been utlized in metal forming. Butyl butanamine stearamide is applicable in lubricants for non‐ferrous metal working, and coatings that can prevent galling when titanium is cold worked can be formed on the metal by the use of 0.5 grams of hydrofluoric acid, with 10 grams stearic acid in 100 ml. of a solvent, the process being accelerated by the inclusion of phosphoric acid at 0.85 grams. Calcium stearate has also been used in solvent‐based metalworking Iubricants, in acrylic electrophoretic lubricant coatings on metal, and in bentonite‐containing metalworking oils. Mixtures of cetyl alcohol and tricresyl phosphate have been cast into slabs and used on metalworking tools.
