The main component of aluminum ingots is aluminum, which is generally between 99% and 99.9% pure. In addition to aluminum, ingots may contain traces of other elements such as silicon, iron, copper and magnesium, which to some extent affect the properties of the ingot. It is the main raw material for the production of a variety of aluminum-based products such as aluminum sheet, foil, profiles and wire. They are available in a range of sizes and weights, with common sizes including small 20 kg ingots and large 1 ton ingots. They are characterized by low density, high thermal and electrical conductivity, good corrosion resistance, good ductility and extensibility. Widely used in aluminum processing industry, construction industry, automotive industry, electrical and electronic industry, packaging industry and so on.

This is the most common type of aluminum ingot, which is mainly used for remelting and processing into various aluminum alloy materials or products. According to national standards, remelted aluminum ingots are classified into grades of Al99.85, Al99.70, Al99.60, Al99.50 and Al99.00 according to their chemical composition. The numbers represent the minimum aluminum content. For example, Al99.85 means that the aluminum content is not less than 99.85% and the total content of other impurities does not exceed 0.15%. This type of aluminum ingot is of high purity and has good electrical and thermal conductivity, corrosion resistance and processing properties. It is widely used in construction, automotive, electronics and packaging industries.

Used for casting various aluminum alloy parts. According to the different alloy composition and performance requirements, can be divided into aluminum-silicon, aluminum-copper, aluminum-magnesium, aluminum-zinc casting aluminum alloy ingots. For example, the common ZL102 belongs to aluminum-silicon casting aluminum alloy ingot. It has good casting performance, corrosion resistance and wear resistance. It is commonly used for casting automobile parts, such as engine blocks, cylinder heads and pistons, as well as various mechanical parts.

It is mainly used to produce various kinds of forged aluminum alloy products, such as aluminum plate, aluminum strip, aluminum foil, aluminum tubes and aluminum profiles through pressure processing (such as rolling, extruding, forging, etc.). Forged aluminum alloy ingots can be divided into 2XXX series (aluminum-copper), 3XXX series (aluminum-manganese), 5XXX series (aluminum-magnesium), 6XXX series (aluminum-magnesium-silicon), 7XXX series (aluminum-zinc-magnesium) and so on according to its main alloying elements. For example, 6061 aluminum alloy ingot belongs to 6XXX series. It has medium strength, good corrosion resistance, weldability and machinability. It is widely used in the manufacture of structural parts for building doors and windows, aerospace and transportation.

Generally refers to aluminum ingots with an aluminum content of not less than 99.99%. High purity aluminum has better electrical conductivity, thermal conductivity, corrosion resistance and light reflection than ordinary aluminum. It is commonly used in the electronics industry to manufacture high-purity aluminum wires, capacitors, semiconductor devices, and so on. It is also used in areas that require extremely high material purity, such as aerospace, optical instruments and high-end scientific research equipment.

They are ingots made from scrap aluminum and aluminum alloy materials recovered through remelting. The composition and properties of recycled aluminum ingots vary depending on the source of the raw material. It can be used as a substitute for primary aluminum in many areas such as construction, automotive parts and foundry, provided it meets certain quality standards. The use of recycled aluminum ingots helps to save energy and reduce the impact on the environment. It is an important way to realize the recycling of aluminum resources.
