The main reason for choosing aluminum alloy materials is the comprehensive strength and density. For the selection of aluminum alloy aluminum sheet materials, we will learn about the aluminum alloy of the 5000 series and the aluminum alloy of the 6000 series.
5000 series aluminum alloy
It is mainly used for sheet metal structural parts. The 5000 series aluminum sheet belongs to the more commonly used alloy aluminum sheet series. The main other element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy.
The main features are: low density, high tensile strength, and high elongation. The density is lower than other series of aluminum alloys. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum sheet series. Mainly in my country, the 5000 series aluminum sheet is one of the more mature aluminum sheet series.
5052 is often used. It has good forming properties, corrosion resistance, weldability, fatigue strength, and medium static strength. It is used to manufacture aircraft fuel tubes, fuel tanks, and sheet metal parts for transportation vehicles and ships.
6000 series aluminum alloy
It is mainly made of machined parts. Unlike the 5000 series, the 6000 series alloy is added with silicon, so the hardness of the 6000 series aluminum alloy is greatly improved and the machining performance is very good. In addition, it is suitable for applications with high requirements for corrosion resistance and oxidation. Easy to layer, high strength, strong corrosion resistance. I often use 6061 aluminum alloy for machined parts with good cutting performance (5000 series is not good).
