ALUMINUM INGOT A7

. Production process of aluminum ingots

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

Description

  1. Definition of aluminum ingots

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

  1. Uses of aluminum ingots

Aluminum ingots are the main raw materials for aluminum processing products such as aluminum profiles, aluminum profiles, aluminum foil, aluminum alloys, aluminum tubes, and aluminum plates. Aluminum 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.

 

  1. Physical and chemical properties of aluminum ingots

Aluminum 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, aluminum ingots have good corrosion resistance and can be exposed to the atmosphere for a long time without being oxidized. In addition, aluminum ingots also have good electrical conductivity, thermal conductivity and mechanical properties.

 

5.Material/Model

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

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

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

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

 

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

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