Heat treatment:
Alloy 5754 can be heat treated 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 Temper: Uniformly rolled and stress relieved to reduce strength.
H22 condition: Strength properties improved by heating and subsequent solution annealing.
Applications:
Alloy 5754 is used in various applications that require high corrosion resistance and strength such as:
Vehicle construction: body parts, trailers, superstructures
Shipbuilding: marine structures, interiors
Container construction: fuel tanks, pressure vessels
Construction: facade cladding, gutters, wall cladding
Industrial applications: heat exchangers, piping, air conditioning
