5251 Aluminium Sheet Tempering

H24 - Work hardened and partially annealed to a half hard state
H26 - Work hardened and partially annealed to a three-quarter hard state
O – Wrought and fully annealed

5251 Aluminium Sheet Welding

Grade 5251 Aluminium alloy is a good weldable alloy.
When welding this alloy to itself it is recommended that use filler wire is 5356.
Filler wire 5356 is also recommended if you are welding 5251 alloys to an alloy of the 6000 series, 7000 series and the majority of 5000 series.
If you are welding either 5251 to 5005 or 5020 or an alloy of the 1000 series and the 3000 series of alloys then we suggest you use filler wire 4043.
