Which is better, pure aluminum or aluminum alloy, for aluminum substrates

       The commonly used metal aluminum based plates for aluminum substrates include 1000 series, 5000 series, and 6000 series

 

        The basic characteristics of these three series of aluminum materials are as follows:

        ① The 1000 series represents 1050, 1060, and 10701000 series aluminum plates, also known as pure aluminum plates. Among all series, the 1000 series has the highest aluminum content, with a purity of over 99.00%. Due to the absence of other technological elements, the production process is relatively simple and the price is relatively cheap, making it the most commonly used series in conventional industry. The majority of products circulating in the market are the 1050 and 1060 series. The minimum aluminum content of the 1000 series aluminum plate is determined based on the last two digits. For example, the last two digits of the 1050 series are 50. According to the international brand naming principle, the aluminum content must reach 99.5% or above as a qualified product. In China's aluminum alloy technical standard (GB/T3880-2006), it is also explicitly stipulated that the aluminum content of 1050 should reach 99.5%. The same principle applies to 1060 series aluminum plates, which must have an aluminum content of over 99.6%.

 

         ② The 5000 series represents the 5052, 5005, 5083, and 5A05 series. The 5000 series aluminum plate is a commonly used alloy aluminum plate 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. Aluminum magnesium alloy has a lower weight than other series under the same area, so it is commonly used in aviation, such as aircraft fuel tanks. In addition, it is also widely used in conventional industries. Its processing technology is continuous casting and rolling, belonging to the hot-rolled aluminum plate series, so it can be used for oxidation deep processing. The 5000 series aluminum plate is one of the more mature aluminum plate series in China.

 

        ③ The 6000 series represents 6061, which mainly contains two elements: magnesium and silicon. Therefore, it combines 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, excellent interface characteristics, easy coating, and good processability. The general characteristics of 6061 include excellent interface features, easy coating, high strength, good usability, and strong corrosion resistance. Typical uses of 6061 aluminum include aircraft parts, camera parts, couplers, ship accessories and hardware, electronic accessories and connectors, etc. Considering the texture, hardness, elongation, chemical properties, and price of the material itself, aluminum substrates generally use 5052 alloy aluminum plates from the 5000 series aluminum materials.
