5 series
Features :Mainly based on magnesium. Good corrosion resistance, good welding performance, good fatigue strength, no heat treatment strengthening, good seawater resistance, so it is often used as a ship's components, but its coloring effect is less than ideal.
Applications :lawn mower handles, aircraft fuel tank conduits, body armor.
5052 :Medium strength weldability and corrosion resistance. Photographic lens housing and camera accessories.
5083 :Has the highest strength in non-heat treated alloys, medium strength alloys, good corrosion resistance and weldability. It has high corrosion resistance to seawater and industrial environments. Shipbuilding, automotive enclosures, railway vehicles, and other high pressure vessels for low temperature applications.
