6060 Aluminum Angle
Product Introduction

| Technical Parameters of Aluminum Angle (Aluminum Angle Bar) | |||
| Parameter Category | Specific Parameter | Description / Typical Values | Common Standards (Examples) |
| Basic Identification | Alloy Designation | Common 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 |
| Temper | Indicates 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 | |

| Mechanical Properties | Ultimate Tensile Strength (UTS) | The maximum stress the angle can withstand. Example (6061-T6): 38 ksi (262 MPa) min Example (6063-T5): 22 ksi (152 MPa) min | ASTM E8/E8M |
| Tensile Yield Strength (TYS) | The stress at which the angle begins to deform plastically. Example (6061-T6): 35 ksi (241 MPa) min Example (6063-T5): 16 ksi (110 MPa) min | ASTM E8/E8M | |
| Elongation at Break | The percentage of plastic deformation before fracture. Example (6061-T6): 8-10% min Example (6063-T5): 8% min | ASTM E8/E8M | |
| Shear Strength | The maximum stress the angle can withstand when forces cause its internal structure to slide against itself. Example (6061-T6): ~24 ksi (165 MPa) | / | |
| Hardness | Typical (6061-T6): Brinell 95 HB | ASTM E10 | |
| Physical & Chemical Properties | Density | Standard Value: 2.70 g/cm³ (0.098 lb/in³) | / |
| Modulus of Elasticity (Young's Modulus) | Standard Value: 10,000 ksi (69 GPa) | / | |
| Chemical Composition | Elemental limits (Al, Mg, Si, Cu, Fe, etc.) as defined by the alloy specification (e.g., for 6061 or 6063) | ASTM B221 | |
| Section Properties (for Structural Design) | Cross-Sectional Area | The total area of the angle's cross-section, used for weight calculation. | Manual Calculation or Reference Tables |
| Weight per Unit Length | Mass per foot or meter. Example: A 2" x 2" x 1/4" 6061-T6 angle weighs approximately 1.77 lb/ft. | Manual Calculation or Reference Tables | |
| Moment of Inertia (Ix, Iy) | A measure of the angle's resistance to bending about its principal axes. Critical for structural deflection calculations. | AISC Steel Construction Manual (Aluminum Section) | |
| Radius of Gyration (r) | A measure used in column buckling analysis. | AISC Steel Construction Manual (Aluminum Section) | |
| Section Modulus (Sx, Sy) | A geometric property used to calculate bending stress. | AISC Steel Construction Manual (Aluminum Section) | |
| Fabrication & Performance | Machinability | Rating (6061-T6): Excellent (Good chip formation, surface finish). | / |
| Weldability | Rating (6061-T6, 6063-T5): Excellent (Typically using GTAW/TIG or GMAW/MIG processes with 4043 or 5356 filler wire). | AWS D1.2 | |
