Aluminum Substrate Copper Claded Laminate Series

The aluminum-based plates commonly used for aluminum substrates mainly include 1000 series, 5000 series and 6000 series. The basic characteristics of these three series aluminum materials are as follows:


11000 series represents 1050, 1060, 1070, 1000 series aluminum plates, also known as pure aluminum plates. In all series, the 1000 series is the most aluminum-containing, with a purity of over 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in the conventional industry. Most of the circulation in the market is the 1050 and 1060 series. The 1000 series aluminum plate is based on the last two digits to determine the minimum aluminum content of the series. For example, the last two digits of the 1050 series is 50. According to the international brand nomenclature, the aluminum content must reach 99.5% to be qualified. In China's aluminum alloy technical standards (GB/T3880-2006), it is also clearly stated that the aluminum content of 1050 reaches 99.5%. The same reason, the aluminum content of the 1060 series aluminum plate must reach 99.6% or more.


The 25000 series represents the 5052, 5005, 5083, and 5A05 series. 5000 series aluminum plate belongs to the more common alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%. It is also called aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series, so it is commonly used in aviation, such as aircraft fuel tanks. In addition, it is widely used in conventional industries. The processing technology is continuous casting and rolling, which belongs to the series of hot-rolled aluminum sheets, so it can be used for deep processing of oxidation. In China, 5000 series aluminum plates belong to one of the more mature aluminum plate series.


The 36000 series represents 6061 mainly containing magnesium and silicon. Therefore, the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. Good usability, excellent interface characteristics, easy coating and good processability.


General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good workability and strong corrosion resistance. Typical uses for 6061 aluminum: aircraft parts, camera parts, couplers, marine parts and hardware, electronic components and connectors. Considering the texture, hardness, elongation, chemical properties and price of the material itself, the aluminum substrate generally uses 5052 alloy aluminum plate in 5000 series aluminum.
