It is well known that iron products will rust after being used for a long time. Will aluminum circle rust as they have been used for a while? Today I want to tell you that the aluminum disc/circle will not rust, because the chemical reaction is different, and the aluminum is only oxidized.
It is understood that when processing aluminum discs, manufacturers will add other anti-rust and anti-corrosion metal elements in the aluminum material, so the aluminum disc/circle produced has anti-rust effect. Manganese alloy is added to the aluminum disc/circle produced. Everyone knows that manganese has a good anti-rust function, so that it can become a rust-proof aluminum disc.
The aluminum pan we usually use is made of aluminum disc. It has a thin oxide film on the surface, only 0.00001 mm thick. In the industry, in order to make the aluminum disc/circle more durable, the finished aluminum disc/circle is processed to make the oxide film thicker, and the aluminum pan thus produced is both afraid of acid and alkali.
In our daily life, people often think that the aluminum pan is not bright enough. It is rubbed with steel balls or sand when cleaning. It is thought that this will make the aluminum products shiny. In fact, this is wrong, because it will be easy. The oxidized film on the surface is wiped off. This protective film is called alumina, which protects the aluminum inside from rust. The characteristic of alumina is that after rubbing off, a new layer of alumina is formed shortly to continue to protect the inner aluminum.
After the above introduction, you should know that the aluminum wafer will not rust for a long time, but only a chemical reaction will occur to produce alumina.
