How many major categories can aluminum bars be roughly divided into?

According to the different metal elements contained in aluminum bars, they can be roughly divided into 8 categories, which means they can be divided into 8 series:

1、 The 1000 series aluminum bars represent the 1050, 1060, and 1100 series. The 1000 series is the series with the highest aluminum content among all series. The purity can reach over 99.00%. Due to the absence of other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industry. The majority of products in circulation on the market are the 1050 and 1060 series. The minimum aluminum content of the 1000 series aluminum rod is determined based on the last two Arabic numerals. For example, the last two Arabic numerals of the 1050 series are 50. According to international brand naming principles, a qualified product must have an aluminum content of 99.5% or higher. The technical standard for aluminum alloys in China (gB/T3880-2006) also specifies that the aluminum content in 1050 should reach 99.5% The same principle applies to 1060 series aluminum bars, which must have an aluminum content of at least 99.6%.

2、 The 2000 series aluminum bars represent 2A16 (LY16) and 2A02 (LY6). The characteristic of the 2000 series aluminum rod is its high hardness, with copper having the highest content, around 3-5%. The 2000 series aluminum bars belong to aviation aluminum materials and are not commonly used in conventional industries.

2024 is a typical hard aluminum alloy in the aluminum copper magnesium series, which belongs to the heat treatable alloy category. It has high strength, is easy to process, is easy to cut, and has average corrosion resistance.

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

The main uses of 2024 aluminum bars include aircraft structures, rivets, truck wheels, propeller components, and various other structural components

3、 3000 series aluminum bars represent 3003 Mainly 3A21. The production process of 3000 series aluminum bars in China is relatively excellent. The 3000 series aluminum rod is mainly composed of manganese element. The content is between 1.0-1.5, making it a series with good rust prevention function.

4、 The representative of the 4000 series aluminum bars is 4A01. The 4000 series aluminum bars belong to the series with high silicon content. The silicon content is usually between 4.5-6.0%. Belonging to building materials, mechanical parts, forging materials, welding materials; Low melting point, good corrosion resistance, product description: It has the characteristics of heat resistance and wear resistance

5、 The 5000 series aluminum bars represent the 5052, 5005, 5083, and 5A05 series. The 5000 series aluminum rod belongs to the commonly used alloy aluminum rod series, with magnesium as the main element and a magnesium content between 3-5%. Also known as 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 industry. The 5000 series aluminum rod is one of the more mature aluminum rod series in China.

6、 The 6000 series aluminum bars represent 6061 and 6063, which mainly contain magnesium and silicon elements, thus combining the advantages of the 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. Good usability, easy coating, and good processability.

7、 The 7000 series aluminum rod represents 7075, which mainly contains zinc element. Also belonging to the aviation series, it is an aluminum magnesium zinc copper alloy, a heat treatable alloy, and a superhard aluminum alloy with good wear resistance Basically relying on imports, China's production technology still needs to be improved.

8、 The commonly used 8000 series aluminum rod is 8011, which belongs to other series and is mostly used for aluminum foil. It is not commonly used in the production of aluminum rods.
