ABSTRACT:
A process for forming a structure of aluminium components comprises pre-treating aluminium sheet to produce an inorganic non-metallic surface coating thereon, forming the pre-treated sheet to produce components of desired shape and applying adhesive to the components and securing them together by means of the adhesive. Generally, an adhesive-compatible press lubricant is present on the sheet when it is formed. The invention also includes aluminium sheet carrying the inorganic non-metallic surface coating and a press lubricant thereon.
