Aluminium Alloy

Commercial Alloy

5754 - H111 Treadplate

Aluminium alloy 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.

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 H111 temper.
