Aluminum alloy is composed of the basic element aluminum and various alloying elements, mainly copper, silicon, magnesium, etc. It is the most widely used metal material in industry, with low density, high strength, good plasticity, excellent conductivity, thermal conductivity, and corrosion resistance. It is widely used in general industry, with a usage rate second only to steel.
1. Low density
The density of aluminum and aluminum alloys is close to 2.7g, which is about one-third of that of iron or copper.
2. High strength
Aluminum and aluminum alloys have high strength. After a certain degree of cold processing, the strength of the matrix can be enhanced, and certain aluminum alloy grades can also be enhanced through heat treatment.
3. Good conductivity and thermal conductivity
Aluminum's conductivity and thermal conductivity are second only to silver, copper, and gold.
4. Good corrosion resistance
The surface of aluminum is prone to producing a dense solid Al2O3 protective film, which can protect the substrate from corrosion. By artificial anodizing and coloring, cast aluminum alloys with good casting performance or deformed aluminum alloys with good plasticity can be obtained.
5. Easy to process
After adding certain alloying elements, cast aluminum alloys with good casting performance or deformed aluminum alloys with good processing plasticity can be obtained. Due to its excellent physical properties, aluminum has been widely used in various industries of the national economy and defense industry.

| 1xxx: 1050, 1050A, 1060, 1100 etc |
| It is with the highest aluminum content, with a purity of over 99.00%. Good formability and surface treatment, with the best corrosion resistance among aluminum alloys. The higher the purity, the lower the strength. 1000 series of aluminum materials are relatively soft, mainly used for decorative or interior parts. |
| 2xxx: 2014, 2017, 2024 etc |
| High hardness, but poor corrosion resistance, with the highest copper content. The copper content is around 3%~5%. The 2000 series aluminum bars belong to aviation aluminum materials and are used as construction materials. Currently, they are not commonly used in conventional industries. |
| 3xxx: 3003, 3004, 3005, 3105, 3A21 etc |
| The 3000 series aluminum rod is mainly composed of manganese element. The manganese content ranges from 1.0 to 1.5, making it a series with good rust prevention function. Commonly used as tanks for liquid products, construction components, construction tools, various lighting components, as well as various pressure vessels and pipelines for sheet metal processing. Good formability, solubility, and corrosion resistance. |
| 4xxx: 4032, 4043 etc |
| Usually, the silicon content is between 4.5% and 6.0%, and higher silicon content results in higher strength, good fluidity, and less solidification shrinkage. It belongs to the category of building materials, mechanical parts, forging materials, and welding materials; Low melting point, good corrosion resistance, heat resistance, and wear resistance. |
| 5xxx: 5005, 5052, 5754, 5083, 5A05, etc |
| The main element is magnesium, with a magnesium content of 3% to 5%. The main characteristics are low density, high tensile strength, and high elongation. The weight of aluminum magnesium alloy is lower than other series under the same area, and it is also widely used in conventional industry. |
| 6xxx: 6061, 6082, 6063 etc |
| The 6000 series aluminum alloy mainly contains magnesium and silicon elements. Therefore, it combines the advantages of the 4000 series and 5000 series. As a representative material of 6000 series, 6061 is a cold treated aluminum forging product suitable for applications with high requirements for corrosion resistance and oxidation resistance. Good usability, easy coating, and good processability. |
| 7xxx: 7075 etc |
| 7000 series mainly contains zinc element. The representative material of 7000 series aluminum alloy is 7075. It belongs to the aviation series. It is an aluminum magnesium zinc copper alloy that can be heat treated. It is a superhard aluminum alloy with good wear resistance. At present, China relies mainly on imports, and its production technology still needs to be improved. |
