Heat treatment:
Alloy 5754 can be heat treated in order to increase its strength. The most common heat treatment conditions are:
O condition, soft: No heat treatment; the material is in the as-supplied condition.
H111 condition: Uniformly rolled and stress-relief annealed in order to reduce strength.
H22 condition: Improved strength properties through heating followed by solution annealing.
Applications:
Alloy 5754 is used in various applications requiring high corrosion resistance and strength, such as
:Vehicle construction: body components, trailers, superstructures
Shipbuilding: marine structures, interior fittings
Tank and vessel construction: fuel tanks, pressure vessels
Construction: façade cladding, gutters, wall cladding
Industrial applications: heat exchangers, piping systems, air-conditioning systems
