The invention relates to a strip or sheet consisting of an aluminium alloy having a unilateral or bilateral surface structure prepared for a forming process, in particular it relates to a strip or sheet for formed motor vehicle components. The object of providing an aluminium alloy strip or sheet having a surface structure prepared for a forming process, which is easy to produce and has improved tribological characteristics in respect of a subsequent forming process, is achieved for a strip or sheet consisting of an aluminium alloy in that the strip or sheet has on one side or on both sides a surface with depressions as lubricant pockets which are produced using an electrochemical graining process.
