Analysis of the difference between non-oxidised and anodised aluminium sheets for sale Haomei

Many customers are curious about the difference between non-oxidised and anodised aluminium sheets for sale. Why should you buy oxidised aluminium sheets? This is because anodised aluminium sheets are very good at resisting oxidation. Isn't that strange? We're here today to explain the difference between anodised and non-oxidised aluminium sheets and the difference between anodised and chemically oxidised aluminium sheets.

The difference between anodising and non-oxidising aluminium sheets:

1, after oxidation, the surface will generate a dense oxide film, so that the aluminium inside no longer continue to oxidise. The non-oxidised aluminium plate can easily be corroded in the air, resulting in yellow or black spots, while the oxidised product will not appear in the air for a long time.

2, anodised aluminium sheets for sale will form a dense oxide film on its surface, so the corrosion resistance will increase, and the melting and boiling point will also increase, which can be used as a heat-resistant material, while the non-oxidised aluminium sheet will not have these properties.

3, anodised aluminium sheets because of a layer of chlorine trioxide oxide film, so corrosion resistance, chemical properties than aluminium more stable. Also, aluminium and acid-base reaction can release hydrogen gas, aluminium sheet anodising will have no gas.

The difference between anodic oxidation and chemical oxidation of aluminium sheets:

1. Whether electricity is required.

Anodic oxidation is carried out in the case of high voltage electricity, it is a kind of electrochemical reaction process; chemical oxidation does not need electricity, but only need to be immersed in the potion on the line, it is a pure chemical reaction.

2. Length of time.

Anodic oxidation takes a long time for anodised aluminium sheets, for sale, often several minutes; chemical oxidation takes only a few dozen seconds.

3. Wear resistance.

Anodic oxidation generated film has a few microns to dozens of microns, and hard wear-resistant; chemical oxidation generated film is only 0.01-0.15 microns or so, wear resistance is not very good, but both conductive and resistant to atmospheric corrosion, which is its advantage.

4、Conductivity.

Aluminum plate anodic oxide film for sale is originally non-conductive; chemical oxidation generated film is really very thin, so that is conductive.
