본 발명은 성형 공정을 위해 준비된 편면 또는 양면의 표면 구조를 갖는 알루미늄 합금으로 이루어진 스트립 또는 시트에 관한 것으로, 특히 성형된 자동차 부품용 스트립 또는 시트에 관한 것이다. 알루미늄 합금으로 이루어지는 스트립 또는 시트에 있어서, 성형 가공을 위해 준비된 표면 구조를 갖는 알루미늄 합금 스트립 또는 시트를 제공하는 목적은 생산하기 쉽고 후속 성형 공정에 대해 개선된 마찰 특성을 갖는다. 상기 스트립 또는 시트는 전기화학적 그레이닝 공정을 사용하여 제조된 윤활제 포켓으로서 함몰부가 있는 표면을 편면 또는 양면에 갖는다. 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.
