The 5000 series, including 5005, 5083, 5052, etc., is the most commonly used aluminum series. 3-5% magnesium is added to the series, so it is also known as aluminium-magnesium alloy. This series of aluminum is processed by continuous casting and rolling technology and belongs to the hot-rolled aluminum series, so it can also be further processed by oxidation. In China, aluminum 5000 series is one of the most mature series. Its main characteristics are low density, high tensile strength and high elongation. The weight of the same area of magnesium-aluminum alloy is lighter than other aluminum series. Therefore, the 5000 series is often used in the aviation industry, for example in aircraft fuel tanks.
