Pure Aluminum Block Electrolytic Aluminum Ingot Die-Casting 99.97% High-Purity Block Aluminum Material Density Increase

The composition of aluminum ingots can be divided into high-grade pure aluminum, industrial high-purity aluminum, and industrial pure aluminum based on their content. According to national standards, aluminum ingots can also be divided into multiple grades, such as AL99.9, AL99.85, AL99.70, etc.
Aluminum ingots have the characteristics of lightweight, high conductivity, and good ductility, which make them widely used in many industries. For example, ADC1 aluminum ingots are commonly used in the manufacturing of overhead wires, ship parts, handles, carving blanks, office appliances, and aircraft electrical installation supplies. In addition, die cast aluminum ingots are mainly used in fields such as automobile manufacturing, furniture industry, and lighting design.
1, What is aluminum ingot?
Aluminum ingot refers to pure aluminum block produced by electrolytic alumina method. Usually, aluminum ingots appear in a square or cylindrical shape. Aluminum ingots are widely used in industries and manufacturing due to their high purity, strength, stability, and corrosion resistance. The production of aluminum ingots is generally carried out through two methods: alumina electrolysis or carbon reduction.
2, Aluminum ingot process
1. Aluminum oxide electrolysis method
The process of producing aluminum ingots by alumina electrolysis mainly includes the following steps:
Extracting bauxite,
Extract alumina using alkali thermal or acid leaching methods,
Aluminum metal is prepared by electrolytic reaction in an electrolytic cell.By pouring aluminum liquid into the aluminum ingot crystallizer through a casting machine,
Cooling, solidification, and aluminum ingot forming;
Package and ship finished aluminum ingots to customers.
In general, aluminum ingots produced by alumina electrolysis method have high purity and good yield, but the process is relatively complex.
2. Carbon reduction method
The process of producing aluminum ingots by carbon reduction method mainly includes the following steps:
Use high-purity carbon and alumina powder, mix and melt in a high-temperature furnace;
After reduction reaction, aluminum alloy is obtained in the reduction furnace;
By pouring aluminum liquid into the aluminum ingot crystallizer through a casting machine,
Cooling, solidification, and aluminum ingot forming;
Package and ship finished aluminum ingots to customers.
Aluminum ingots produced by carbon reduction method are generally cheaper, but their purity is relatively low.
classification
Aluminum ingots are classified into three types based on their composition: aluminum ingots for remelting, high-purity aluminum ingots, and aluminum alloy ingots; According to shape and size, it can be divided into several types such as bar ingots, round ingots, plate ingots, T-shaped ingots, etc.
Aluminum alloy ingot: It is an alloy made from pure aluminum and recycled aluminum as raw materials, and other elements such as silicon (Si), copper (Cu), magnesium (Mg), iron (Fe) are added according to international standards or special requirements to improve the castability, chemical and physical properties of pure aluminum.
Several common aluminum ingots
Aluminum ingots for remelting -15kg, 20kg (≤ 99.80% Al):
T-shaped aluminum ingot -500kg, 1000kg (≤ 99.80% Al):
High purity aluminum ingot -10kg, 15kg (99.90%~99.999% Al);
Aluminum alloy ingots -10kg, 15kg (Al Si, Al Cu, Al Mg);
Plate ingot -500-1000kg (for plate making);
Round ingot -30-60kg (for wire drawing).
