  • Lubricant and method of cold-rolling aluminum
    Patent number: 4844830
    Abstract: Load-bearing additives for lubricants for cold-rolling aluminum, particularly foil rolling down to a thickness below 50 microns, comprise a methyl ester of a saturated straight-chain C10-C14 carboxylic acid, particularly methyl dodecanoate. A saturated straight-chain C10-C14 alcohol, or a saturated straight-chain C8-C14 carboxylic acid may also be present. The lubricants permit greater rolling speeds and improved foil properties during and after annealing.

  • Metal forming lubricant
    Patent number: 4687587
    Abstract: A lubricant for metal forming comprises a dispersion of particles of a waxy material in a solution or dispersion in a volatile liquid medium of a monomeric organic carrier which is a solid or a viscous liquid at ambient temperature. The particles may be 5-25 microns, the volatile liquid may be xylene, the carrier may be an ester with a MW below 320 and the weight ratio of particles to carrier may be 1:1 to 6:1. The waxy particles provide good lubricating performance without coalescing under load. The lubricant is compatible with adhesive and is easily removed from a workpiece.
