Chromized and Dos Treated Aluminium Sheet
Chromized and dos treated aluminium sheet acquires a range of superior properties and characteristics that make the treated stock more suitable for bottle cap production and applications. Chromized and dos treated aluminium sheet offer a number of unique advantages. First of all, chroming treatment can form a uniform and dense chromium oxide layer on the surface of the aluminium sheet. This chromium oxide layer not only effectively prevents the erosion of the aluminum sheet by rain, chemicals and other environmental factors, but also improves the corrosion resistance of the aluminum sheet in corrosive media such as liquor and beverages, which greatly extends the service life of the aluminum sheet. At the same time, because the formation of chromium oxide film is carried out through physical and chemical oxidation reaction, its coverage of the surface of the aluminum sheet uniformity is good, without special mechanical and chemical treatment. In addition, t...
