Recently, many customers have asked whether the aluminium sheet is oxidized, and even many customers directly equate the alumina sheet with the alumina sheet. In this part of customers'eyes, the biggest difference between the aluminium sheet and the alumina sheet is that the surface texture is not the same. Is that the fact?
In fact, both aluminium sheet and alumina sheet are made by different surface treatment processes on the basis of aluminium sheet. Aluminum sheet is a kind of manufacturing process that scrapes aluminium sheet out of the line repeatedly with sandpaper. Until various required drawing effects are formed on the surface of aluminium sheet, alumina sheet forms a thin layer of oxygen on the surface of aluminium sheet by physical or chemical means. Aluminum sheet with aluminium film, then drawing aluminium sheet is equivalent to alumina sheet, the answer is no!
First of all, many different series of drawing aluminium sheet have their own unique properties of aluminium sheet, which are manifested in its drawing effect, corrosion resistance and stain resistance. It is of course necessary to add some oxidation in the process of drawing, but this is not the same as drawing aluminium sheet, which is not scientific.
Secondly, there are also many series of alumina sheets, but they all have a common feature is that the surface of alumina sheets with oxide film, the surface of which is quite different from that of aluminium sheets with drawing texture.
Finally, it needs to be explained that whether aluminium sheet or alumina sheet is drawn, the application in real life is based on different scenarios to choose, must not be confused, let alone alumina sheet or aluminium sheet is drawn such a good problem!
