Material Group 22.3 ISO/TR 15608 such as EN AW-5754:
Non heat treatable aluminium-magnesium-alloys with 1,5 < Mg ≤ 3,5 %
Features of Al-Mg-Alloys such EN AW-5754 alloy
The Al-Mg-Alloys are corrosion-resistant in seawater and industrially polluted atmospheres, have highest strengths for aluminium alloys, and are not hardenable (by heat treatment). This is used for apparatus and pipes in the chemical industry for roof cladding, wall coverings, pressure vessels, roller shutters, roller doors, storage tanks and heat exchangers.
The material has a good weldability and is weldable by standard techniques.
Al-Mg-Alloy EN AW-5754 is suitable for the manufacture of pressure vessels and piping in accordance with EN 1392 “Aluminum and aluminum alloys – Wrought and cast products – Particular requirements for products for the fabrication of pressure equipment” see table below.
