Abstract
A lubricant is provided which has a hardness in the range 0.1-10 N/mm at all temperatures in the range 15-40° C. The lubricant consists of at least one full ester of a glycol with a fatty acid, e.g. ethylene glycol dilaurate, optionally mixed with a minor amount of a fatty acid such as stearic acid, and/or a minor amount of a partial ester of a glycol with a fatty acid. The lubricant is useful in the production of press-formed components, and particularly in techniques for converting aluminium sheet to adhesively bonded aluminium structures.
