Lubricant for forming aluminum and aluminum alloy and aluminum and aluminum alloy sheet for forming

摘要

Lubricants for forming aluminum and aluminum alloy sheets, which are easy to remove after the molding and assembly of aluminum and aluminum alloy sheets are finished, and also with the application of the lubricant and the adhesion and dissolution It is intended to provide a lubricant that can be brought into contact and that the obtained adhesion or welding strength is equivalent to that in the case where the lubricant is not adhered. A polyalkylene oxide or its derivatives and a fatty acid salt are the main components. The polyalkylene oxide or its derivatives are contained in the amount of 50 to 2% by weight, and the proportion of the higher fatty acid salt and the polyalkylene oxide or the derivative thereof is within the range of 1 / 12 to 1 / 4 and preferably water. This lubricant is made of a solid film of 0.2 to 2.0 g / m.sup. 2 on the surface of aluminum or aluminum alloy plate, and is suitable for molding.
