6005 Aluminum Angle

Product Introduction

Technical Parameters of Aluminum Angle (Aluminum Angle Bar)
Parameter CategorySpecific ParameterDescription / Typical ValuesCommon Standards (Examples)
Basic IdentificationAlloy DesignationCommon alloys used for angle extrusion.
Common Alloys:
• 6061-T6: Most common; high strength, excellent machinability and weldability. General structural use.
• 6063-T5/T6: Good surface finish, corrosion resistance; used for architectural and moderate-strength applications.
• 6063-T52: A specific temper for angles, offering a good balance of strength and formability.
• 2024-T3: Very high strength, primarily used for aerospace applications.
ASTM B221, ASTM B316, AMS-QQ-A-200/8
TemperIndicates the mechanical strength.
Common Tempers:
• T6: Solution heat-treated and artificially aged (highest strength for 6xxx series).
• T5: Cooled from an extrusion process and artificially aged.
• T52: Strain-hardened and then artificially aged (specific to angles/channels).
ASTM B221
Dimensional SpecificationsLeg Size (A x B)The dimensions of the two perpendicular legs.
Typical Range: 1/2" x 1/2" (12.7mm x 12.7mm) to 6" x 6" (152mm x 152mm) and larger. Can also be unequal leg (e.g., 2" x 3").
/
Thickness (t)The thickness of the legs.
Typical Range: 1/16" (1.6mm) to 1/2" (12.7mm) and thicker.
