5754 - H114 Sheet

Aluminium 5754 has excellent corrosion resistance especially to seawater and industrially polluted atmospheres.
It has higher strength than 5251. This high strength makes 5754 highly suited to flooring applications.

Applications
5754 is typically used in:
~ Treadplate
~ Shipbuilding
~ Vehicle bodies
~ Rivets
~ Fishing industry equipment
~ Food processing
~ Welded chemical and nuclear structures

Please note that Mechanical Properties shown are for H114 temper.

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
H114

Supplied Forms

Alloy 5754 is typically supplied as treaplate
