Background

Aluminium 5754 has excellent corrosion resistance especially to seawater and industrially polluted atmospheres.

It has higher strength than 5251. This high strength makes Aluminium 5754 highly suited to flooring applications.

After rolling, Aluminium 5754 spontaneously softens until it reaches a stable condition.

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

Aluminium 5754 is typically used in:

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

Supplied Forms

Aluminium 5754 is typically supplied by Aalco as either 5-bar treadplate or rice grain treadplate
