Temper
The most common tempers for 5754 aluminium are
shown below with H111 being the most common
treadplate temper
·
O – Soft
·
H111 - Some work hardening imparted by shaping
processes but less than required for H11 temper
·
H22 - Work hardened by rolling then annealed to
quarter hard
·
H24 - Work hardened by rolling then annealed to half
hard
·
H26 - Work hardened by rolling then annealed to
three-quarter hard
