FIELD: metallurgy.
SUBSTANCE: it is manufacture metallic sheet made of aluminium alloy. For this it is implemented plate foundring for rolling with optional following homogenisation. Then it is implemented one or several operations of hot or cold rolling, at that it can be implemented one or several operations of reheating for sheet receiving. Then unreliably it is implemented one or several operations of cutting-off or finishing treatment sheet. Then it is implemented preliminary mechanical treatment with removing of material of mentioned sheet at one or two front-face area. It is implemented heat processing for solid solution and tempering.
EFFECT: details allows improved balance between static mechanical characteristic and minimise appearing during tempering at manufacturing of curvature details.
