ASTM B209 5052 aluminum sheet medium to high strength magnesium alloy sheet
Description of 5052 aluminum sheet:
5052 aluminium is a higher strength non-heat treatable alloy with 2.5% magnesium, 0.25% chromium alloy, commonly available in flat rolled coil, sheet and plate from a wide range of producing mills. When annealed it is stronger than 1000 series & 3000 series. The alloy benefits from a medium to high fatigue strength making it an excellent choice for use in structures which are exposed to excessive vibrations. 5052 also offers very good resistance to corrosion, especially in marine application. With good weldability and formability characteristics, the alloy can be used in a wide range of applications. Alloy 5052 is also produced as a treadplate with mainly industrial applications.
