1. Definition of Aluminium ingots

Aluminium ingot is an industrial raw material. It is a block product of Aluminium obtained after electrolytic refining. It plays an important role in the Aluminium industry. The production process of Aluminium ingots is to electrolytically refine the smelted Aluminium liquid in an electrolytic tank.

2. Production process of Aluminium ingots

There are two main methods for the production of Aluminium ingots: the traditional alumina melting electrolysis method and the new direct Aluminium alloy electrolysis method. The alumina smelting electrolysis method refers to first smelting raw materials such as phosphorite and Aluminium hydroxide to obtain alumina, and then electrolytically refining the alumina in an electrolytic tank to obtain Aluminium ingots; while the direct Aluminium alloy electrolysis method is to smelt Aluminium and other The alloying elements are dissolved in the molten salt, and Aluminium ingots and alloys are obtained directly through electrolysis.

3. Uses of Aluminium ingots

Aluminium ingots are the main raw materials for Aluminium processing products such as Aluminium profiles, Aluminium profiles, Aluminium foil, Aluminium alloys, Aluminium tubes, and Aluminium plates. Aluminium ingots are not only widely used in aviation, aerospace, automobiles, home appliances, rail transit, electronics and other industries, but also have great uses in construction, packaging and pharmaceutical fields.

4. Physical and chemical properties of Aluminium ingots

Aluminium ingot is a silver-gray block that has good toughness and ductility and can be easily cut, forged and stretched into various shapes. At normal temperatures, Aluminium ingots have good corrosion resistance and can be exposed to the atmosphere for a long time without being oxidized. In addition, Aluminium ingots also have good electrical conductivity, thermal conductivity and mechanical properties.

5.Material/Model

According to the composition content of Aluminium ingots, they are divided into

①High-grade pure Aluminium: Aluminium content 99.93%-99.999%2)

②Industrial high-purity Aluminium: Aluminium content 99.85%-99.90%3)

③Industrial pure Aluminium: Aluminium content is 98.0%-99.7%.

Aluminium ingots for remelting are divided into 6 grades according to their chemical composition: (Note: the number after A1 is the Aluminium content)

AL99.9, AL99.85, AL99.70, AL99.70A, AL99.60, AL99.50, AL99.00
