Heat treatment:
Alloy 6066 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.
T4 Temper: Solution treated and naturally aged to achieve a balanced combination of strength and toughness.
T6 condition: solution annealing and artificial aging to achieve higher strength values.
Applications:
Alloy 6066 is used in various applications that require high strength and good corrosion resistance, such as:
Vehicle construction: Automobile frames, chassis components
Aerospace: aircraft structural parts, space components
Sports equipment: bicycle frames, golf clubs
Industrial applications: machine parts, housings, frame constructions
