Aluminum ingot according to the national standard (GB/T 1196-2008) should be called "remelting aluminum ingot", but we used to call "aluminum ingot". Aluminum is a silver-white metal that is the third most abundant in the earth's crust after oxygen and silicon. Aluminum is also called a light metal because its density is only 34.61% of iron and 30.33% of copper.

1. The classification of aluminum ingots


Aluminum is the world's output and consumption are second only to iron and steel non-ferrous metal. Aluminum has a density of only 2.7103g/cm³, about one-third that of steel, copper, or brass. Aluminum ingot is the raw material of our daily industry. According to Chinese national standard, it should be "aluminum ingot for remelting". It is produced by electrolysis with alumina and cryolite. According to processing methods, aluminum ingots can be divided into two categories: cast aluminum alloys and deformed aluminum alloys. Aluminum ingots are divided into high purity aluminum ingot and aluminum alloy ingot for remelting according to different components. According to shape and size, it can be divided into bar ingot, round ingot, plate ingot, T - shaped ingot and so on.

2. Several common aluminum ingots


Aluminum ingot for remelting --15kg, 20kg (≤ 99.80%Al): 

T-shaped aluminum ingot --500kg, 1000kg (≤ 99.80%Al): 

High purity aluminum ingot -- L0kg, 15kg (99.90% ~ 99.999%Al);

Aluminum alloy ingot --10kg, 15kg (Al--Si, Al--Cu, Al--Mg);

Plate ingot -500 ~ 1000kg (for plate making);

Round ingot --30 ~ 60kg (for wire drawing).

3. The production process of aluminum ingot

In order to make our customers know more about aluminum ingot, we will popularize its production process, so that you will not have difficulties in the process of purchasing.

The production of aluminum ingot is composed of bauxite mining, alumina production, aluminum electrolysis and other production links.

First mining bauxite, through washing, grinding and other processes to produce aluminum powder, and then through roasting and other four complex processes to get alumina.

Of the proven global reserves of bauxite, 92% are weathered laterite type bauxite, belonging to the bauxite trihydrate type. These bauxite ores are characterized by low silicon, high iron, and high al-Si ratio, and are concentrated in West Africa, Oceania, and Central and South America. Due to the different characteristics of the three kinds of bauxite, the alumina production enterprises have adopted different production techniques in production, mainly including Bayer method, alkali lime sintering method and Bayer sintering combined method. Generally, high grade bauxite is produced by Bayer process and medium and low grade bauxite is produced by combined process or sintering process. Due to its simple process and low energy consumption, Bayer process has become the most important method used in alumina production, accounting for about 95% of the total global alumina production.

Aluminum oxide under the action of strong current, electrolytic aluminum metal, this process is called electrolytic aluminum.

4. The use of aluminum ingots

Because aluminum is light, aluminum ingots are widely used in many industries such as construction, power, packaging, transportation and consumer goods. It can be used in the production of aluminum sheet, foil, aluminum alloy, and anti-corrosion packaging materials, and can also be used in aluminum alloys, utensils, cables, conductive bodies, core alloys, decoration materials, and daily necessities in the chemical industry. Aluminum ingots can also be alloyed with other metals such as silicon, copper, magnesium, iron, etc. to improve the lack of forgeability, chemical and physical properties of pure aluminum.

Due to the dense oxide protective film on the surface of aluminum ingots, it is not easy to be corroded.

Aluminum ingot is a good conductor of heat, and its thermal conductivity is three times greater than that of iron. Aluminum can be used in the industry to manufacture various heat exchangers, heat dissipation materials and cooking utensils. Aluminum ingots have good ductility, second only to gold and silver in ductility, and can be made into aluminum foils thinner than 0.01 mm at 100 °C to 150 °C. These aluminum foils are widely used for packaging cigarettes, candies, etc. It can be made into aluminum wire, aluminum strip, and can roll various aluminum products.

5. The price of aluminum ingots 

Our company has long maintained the model of "organizing production according to customer orders" and implemented the product sales pricing principle of "aluminum ingot price + processing fee". If you have any need of our aluminum products, please feel free to contact us for the latest price.
