Aluminium alloy sheet with roughened surface
摘要:
There is disclosed a process for producing an aluminium alloy sheet, which comprises subjecting a surface of the sheet to anodising conditions to form on the surface an aluminium oxide barrier layer of thickness 10 to 50 nm and treating the oxide layer with an aqueous solution of alkali to remove the layer, thereby leaving a roughened surface on the alloy sheet.
