The main reason for choosing alloy sheet aluminum for sale is the overall strength and density. For the selection of aluminum alloy 4x8 aluminum sheet materials, we will understand the aluminum alloy of the 5000 series and the aluminum alloy of the 6000 series. 1. 5000 series aluminum alloy Mainly used for sheet metal structural parts. The 5000 series sheet aluminum on sale belongs to the more commonly used alloy aluminum plate series. The main other element is magnesium, and the content of magnesium 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 series. Mainly in my country, 5000 series aluminum plate is one of the more mature aluminum plate series. 5052 is often used. It has good formability, corrosion resistance, weldability, fatigue strength and moderate static strength. It is used to manufacture aircraft fuel pipes, fuel tanks, and sheet metal parts for transport vehicles and ships. 26000 series aluminum alloy The 6000 series aluminum sheets sold are mainly used for machining parts. Different from the 5000 series, silicon is added to the 6000 series alloy, which greatly improves the hardness of the 6000 series aluminum alloy and the processing performance is very good. The typical alloy of 6000 series aluminum sheet is 6061 aluminum sheet. In addition, it is suitable for applications requiring high corrosion and oxidation resistance, easy delamination, high strength and strong corrosion resistance. I usually use 6061 aluminum alloy to machine parts with good cutting performance.
