The main differences are as follows:
The 5-series aluminum profile is a deformed aluminum alloy containing Mg as the main alloying element, that is, Al-Mg.
The 5 series belongs to the more commonly used alloy aluminum series. The main element is magnesium, and the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. Therefore, it is commonly used in aviation and ships, and is widely used in conventional industries.
5000 series aluminum alloys represent the 5052, 5005, 5083, 5A05 series. The 5000 series aluminum rods belong to the more commonly used alloy aluminum plate series.
The 6-series aluminum profile is a deformed aluminum alloy of Mg and Si main alloying elements, that is, Al-Mg-Si.
The 5 series aluminum alloy is a non-heat treatable reinforced aluminum alloy profile.
The 6 series aluminum alloy is a heat treatable reinforced aluminum alloy profile.
The characteristics of the 6-series aluminum are: medium strength, good plasticity and excellent corrosion resistance. In particular, it has a tendency to be free from stress corrosion cracking, has excellent weldability, good corrosion resistance and cold workability, and is a widely used and promising alloy.
