Probably many people don't know that the 5083 aluminum plate is an amphoteric metal, which means it can be dissolved in alkali or acid. Of course, if you are not too clear, you can take a look as below:

Zinc hardly changes in dry air. In humid air, a basic zinc carbonate film will be formed on the zinc surface. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is poor. The 5083 aluminum plate is particularly susceptible to corrosion in the atmosphere of high temperature and high humidity containing organic acids. The standard electrode potential of zinc is -0.76V. For the steel substrate, the zinc coating is an anodic coating, which is mainly used to prevent corrosion of steel. The protection performance of the 5083 aluminum plate has a great relationship with the thickness of the coating. After passivation treatment, dyeing or coating of light protection agent, the zinc coating can significantly improve its protection and decoration. The composition range of steel types is shown in the table. The high-pressure vessels and pipelines widely used in high-pressure engineering have been used in extremely high or low temperatures for a long time.Zinc plating refers to the coating of a layer of zinc on the surface of metals, alloys or other materials for beauty and rust Equivalent surface treatment technology. Zinc is easily soluble in acids. Production process and casting equipment Cold-rolled 5083 aluminum sheet continuous casting billet production process Cold-rolled weathering steel continuous casting billet production process is: blast furnace ironmaking → converter smelting → refining → slab continuous casting → hot rolling plant. Cold-rolled 5083 aluminum slab side crack steel composition and casting conditions Cold-rolled 5083 aluminum plate that produces side cracks is mainly used for container plates. Even in a chemically corrosive environment, it is often required to use special alloy steel to make it large The thick-walled tube container can be made by welding with steel plates, or manufactured by forging seamless cylinders.

The production method of this type of aluminum plate can be traced back to the pipe manufacturing method invented by Ehhardt in 1899 (EhrhardtProeess named after his perforation and topping process, a more economical method for producing thick-walled seamless pipes and cylinders So far, this production method can be produced using steel ingots with a unit weight of 26 tons or more. Since this process is basically the same as the current pipe jacking process, this production method can be called a large jacking pipe production process. This method is still relatively advanced so far. There are such production plants in West Germany and Japan, and many users around the world order such products, so the production cost is greatly reduced.
