5754 aluminium alloy is an alloy in the wrought aluminium -magnesium family (5000 or 5xxx series). It is closely related to 5154 aluminum alloy and 5454 aluminum alloy. Of the three 5×54 alloys, 5754 is the least alloyed (highest composition % of aluminium), but only by a small amount. It is used in similar applications. As a wrought alloy, it can be formed by rolling, extrusion, and forging, but not casting. It can be cold worked to produce tempers with a higher strength but a lower ductility.

Aluminium 5754 has excellent corrosion resistance especially to seawater and industrially polluted atmospheres. It has higher strength than 5251 aluminum alloy. This high strength makes Aluminium 5754 highly suited to flooring applications. After rolling, Aluminium 5754 spontaneously softens until it reaches a stable condition.

Welding

Aluminium 5754 has excellent weldability. The recommended filler alloy is 5356.

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

Applications of Aluminium 5754:

• Treadplate
• Shipbuilding
• Vehicle bodies
• Rivets
• Fishing industry equipment
• Food processing
• Welded chemical and nuclear structures
