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.

Pharmaceutical foil, also known as medical-grade foil or blister foil, 8011,8021,8079 aluminum foil common used for Pharmaceutical packaging foil.
Hydrophilic aluminum foil is obtained by coating the surface of aluminum foil with hydrophilic coating, the purpose is to improve the hydrophilic (water-attracting) performance of the aluminum foil, and it has higher heat transfer efficiency and corrosion resistance.
As a professional manufacturer and exporter of aluminum foil jumbo roll seals in China. We have been in this field for more than 20 years, we have a factory and dust-free workshop of more than 100,000 square meters
5086 aluminum sheet is a high-strength, corrosion-resistant al-mg alloy, widely used in aerospace, transportation, architectural decoration and other fields.
3004 aluminum coil is an aluminum-manganese alloy, which is the most widely used anti-rust aluminum. The strength of this alloy is not high. It is similar to 3003 alloys with about 1% magnesium added.
Among the various aluminum alloys available, the 2014 aluminum plate has carved a niche for itself, particularly in applications demanding high strength, excellent machinability, and resistance to fatigue.

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.
