Abstract A metal-working lubricant comprises an aqueous emulsion of a) a long-chain aliphatic ester, amide, alcohol or acid, and b) as a fugitive emulsifier an ammonium or volatile amine salt of a long-chain aliphatic acid. On application to sheet, e.g. of aluminium metal with a chromate or anodic oxide protective surface layer, the water and ammonia or volatile amine evaporate to leave a storage-stable hydrophobic lubricant. The sheet can be formed or made into adhesively bonded structures of shaped components.
