5252 Aluminum Sheet, Aluminum Sheet Manufacturer, Aluminum Sheet Supplier. Aluminum Sheet Metal:
5251 aluminum sheet is provided by Henan Mingtai Aluminum with a medium strength alloy possessing good ductility and therefore good formability. 5251 aluminum sheet is known for work hardening rapidly and is readily weldable. Like all the 5000-series high magnesium alloys, 5251 aluminum sheet has a fairly high strength and is hardenable to a significant degree by cold working, enabling a series of H tempers and conforming to ASTM B209M.
The most common tempers for 5251 aluminium are:
H24 - Work hardened by rolling then annealed to half hard
H26 - Work hardened by rolling then annealed to three-quarter hard
O - Soft
H22 - Work hardened by rolling then annealed to quarter hard
Aluminium alloy 5251 is a readily weldable alloy.
The recommended filler wire is 5356 when welding alloy 5251 to itself, 6XXX series alloys, 7XXX series alloys and most other 5XXX alloys.
When welding alloy 5251 to 5005, 5020, 1XXX series or 3XXX series alloys, the recommended filler wire is 4043.
Weldability – Gas: Very Good
Weldability – Arc: Very Good
