This standard applies to the dimensional tolerances of wrought aluminum and aluminum alloy rolled plates and strips.
Rolled products with a rectangular cross-section, uniform thickness and greater than 0.20mm, usually cut or sawn at the edges, and delivered in a straight shape. The thickness does not exceed 1/10 of the width.
A rolled product with a rectangular cross-section and a uniform thickness greater than 0.20 mm. Usually the edges are slit and delivered in rolls. The thickness does not exceed 1/10 of the width.
Finished products with a width greater than 1500mm or a length greater than 4000mm are called large-size plates.
5A03, 5A05, 5A06, 5083, 5086, 5A41 and other aluminum-magnesium alloy ordinary grade plates and strips with an average magnesium content greater than or equal to 3% and a thickness greater than or equal to 4.0mm, the allowable deviation is ±5% of the nominal thickness, The allowable deviation of the thickness of other aluminum and aluminum alloy ordinary grade plates and strips shall comply with the provisions in the table below.

Świetny artykuł. Byłem zachwycony, że wyszukałem ten artykuł. Wielu osobom wydaje się, że mają rzetelną wiedzę na ten temat, ale często tak nie jest. Stąd też moje miłe zaskoczenie. Jestem pod wrażeniem. Zdecydowanie będę rekomendował to miejsce i częściej wpadał, aby zobaczyć nowe rzeczy.
