1. The alloy composition of the 6 series aluminum alloy is magnesium and silicon, one to enhance corrosion resistance and the other to enhance mechanical properties. The main alloy component of the 5-series aluminum alloy is magnesium, and the magnesium content reaches 3%-5%.
2, 5 series aluminum alloy is lighter than 6 series, so it can be used in aircraft and ship fields. Like aircraft skins, fuel tank parts, bulletproof decks, etc. The 6 series aluminum profiles have better mechanical properties and are mainly used for supporting parts in the industrial and construction fields.
3. The 5 series aluminum alloys are mainly used as rolled materials, aluminum plates, etc., because of their better welding performance, they are also used for welding structural parts; the 6 series aluminum alloys profiles are mainly used as aluminum profiles because of their good deformability, mainly Hot extruded profiles and die castings are also available. Of course, 6-series aluminum alloys are also used as plates, such as 6009 and 6010 for automotive plates, and 6061 can also be used as aluminum plates. 5 series aluminum alloys profiles are also used as profiles. For example, 5050 5a06 aluminum alloy can be used for pipes and profiles.
The characteristics of the 5 series aluminum alloy are: low density, high tensile strength, and high elongation.
The characteristics of the 6 series aluminum alloy profiles are: medium strength, good plasticity and excellent corrosion resistance. In particular, it has no stress corrosion cracking tendency, excellent weldability, good corrosion resistance and cold workability, and it is a very promising alloy with a wide range of applications.
