2. 2000 series aluminum rods represent 2A16 (LY16) and 2A02 (LY6). The characteristics of 2000 series aluminum rods are high hardness, among which the copper content is the highest, about 3-5%. 2000 series aluminum rods belong to aviation aluminum materials and are not often used in conventional industries.

2024 is a typical hard aluminum alloy in the aluminum-copper-magnesium system. It is a heat-treatable alloy with high strength, easy processing, easy turning, and general corrosion resistance.

After heat treatment (T3, T4, T351), the mechanical properties of 2024 aluminum rods are significantly improved. Its T3 state parameters are as follows: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation: 10%, fatigue strength 105MPa, hardness 120HB.

The main uses of 2024 aluminum rods: aircraft structures, rivets, truck wheels, propeller components and other structural parts

3. 3000 series aluminum rods are mainly represented by 3003 and 3A21. my country's 3000 series aluminum rod production process is relatively excellent. 3000 series aluminum rods are mainly composed of manganese elements. The content is between 1.0-1.5, which is a series with good anti-rust function.

4. 4000 series aluminum rods are represented by 4A01. The 4000 series aluminum rods belong to the series with high silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance, product description: It has heat-resistant and wear-resistant characteristics

5. 5000 series aluminum rods represent 5052, 5005, 5083, 5A05 series. 5000 series aluminum rods belong to the more commonly used alloy aluminum rod series. The main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. 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 industries. In my country, 5000 series aluminum rods belong to one of the more mature aluminum rod series.

6. 6000 series aluminum rods represent 6061 and 6063, which mainly contain two elements of magnesium and silicon, so they concentrate the advantages of 4000 series and 5000 series. 6061 is a cold-treated aluminum forging product, suitable for applications with high requirements for corrosion resistance and oxidation resistance. It has good usability, easy coating and good processability.

7. 7000 series aluminum rods represent 7075, which mainly contains zinc. It also belongs to the aviation series, is an aluminum-magnesium-zinc-copper alloy, is a heat-treatable alloy, belongs to a super-hard aluminum alloy, and has good wear resistance. It basically relies on imports, and my country's production technology needs to be improved.

8. 8000 series aluminum rods: The more commonly used ones are 8011, which belongs to other series. Most of them are used for aluminum foil and are not commonly used in the production of aluminum rods.
