We all know that aluminum alloy material production has a certain size deviation, today 7075 aluminum plate manufacturer would like to introduce to you, 7075 aluminum plate thickness deviation factors.

The transverse thickness deviation of 7075 aluminum plate is called the transverse thickness difference (plate crown), and the influence of the edge thinning of 7075 aluminum plate can be ignored.The transverse thickness difference is determined by the cross-section shape of the 7075 aluminum plate.The transverse thickness difference of rectangular section is zero, which is the ideal situation that users expect.The wedge section is thick on the other side and thin on the other side, and the lateral difference is mainly due to improper pressure adjustment on both sides, or rolling loss in part.Symmetric convex or concave sections show the thickness of the middle section and the thickness of the middle section and the thickness of the middle section.In most cases, the middle thickness is thinner on both sides, and the transverse thickness difference is mainly caused by the shape of the roll gap in the rolling process, that is, the longitudinal elongation of the metal is not evenly distributed along the transverse.If the elastic recovery of the rolled piece is not taken into account, it can be considered that the transverse thickness difference of 7075 aluminum plate is actually equal to the opening difference of the work roll seam within the plate width.

The transverse thickness difference or plate crown is usually expressed as the difference between the thickness of the middle part of the rolled piece and the thickness of the edge of the cross section of the rolled piece.In order to improve the stability and alignment of the rolled piece, it is sometimes necessary to have a certain degree of convexity on the strip section, but this will reduce the accuracy of the transverse thickness.
