AlMg3-W19欧标铝镁合金

Aluminium alloy AlMg3/5754 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 W19/H111 temper.

Temper Types

The most common tempers for 5754 aluminium are shown below with H114 & 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

•H114
