Product Introduction
| Technical Parameters of Aluminum Bar | |||
| Parameter Category | Specific Parameter | Description / Typical Values | Common Standards (Examples) |
| Basic Identification | Alloy Designation | Common alloys used for bar production. Common Alloys: • 2024-T3/T351: Very high strength, excellent fatigue resistance. Primarily for aerospace applications. Poor corrosion resistance without cladding. • 6061-T6/T651: The most common general-purpose alloy. Good strength, excellent corrosion resistance, machinability, and weldability. • 7075-T6/T651: Ultra-high strength. Used in high-stress structural aerospace and military applications. • 2011-T3: Excellent machinability (free-machining alloy). Used for screw machine products. | ASTM B211, ASTM B221, AMS 4120 (2024), AMS 4127 (7075) |
| Temper | Indicates the mechanical strength and processing. Common Tempers: • T3: Solution heat-treated, cold worked, and naturally aged. • T6: Solution heat-treated and artificially aged. • T651/T6511: Solution heat-treated, stress-relieved by stretching, and artificially aged. This temper provides improved dimensional stability for machining. | ASTM B211 | |
| Dimensional Specifications | Product Form | • Round Bar • Square Bar • Hexagonal (Hex) Bar • Rectangular Bar | / |
| Diameter (Round) / Width (Square) / Across Flats (Hex) | Typical Range: 3 mm (1/8") to 500 mm (20+ inches). | / | |
| Length | Standard random lengths (e.g., 12 ft, 16 ft, 6m) or cut-to-length. | / | |
| Diameter/AF Tolerance | Allowable deviation from the specified dimension. Tighter tolerances are available for precision machining. | ASTM B211 | |
| Straightness Tolerance | Allowable deviation from a straight line along the length of the bar. | ASTM B211 | |
| Mechanical Properties | Ultimate Tensile Strength (UTS) | The maximum stress the bar can withstand. Example (6061-T6): 42 ksi (290 MPa) min Example (2024-T3): 64 ksi (441 MPa) min Example (7075-T6): 78 ksi (538 MPa) min | ASTM E8/E8M |
| Tensile Yield Strength (TYS) | The stress at which the bar begins to deform plastically. Example (6061-T6): 38 ksi (262 MPa) min Example (2024-T3): 47 ksi (324 MPa) min Example (7075-T6): 69 ksi (476 MPa) min | ASTM E8/E8M | |
| Elongation at Break | The percentage of plastic deformation before fracture. Example (6061-T6): 8-10% min Example (2024-T3): 10-12% min Example (7075-T6): 7% min | ASTM E8/E8M | |
| Shear Strength | The maximum stress the bar can withstand when forces cause its internal structure to slide against itself. Example (6061-T6): ~24 ksi (165 MPa) Example (7075-T6): ~41 ksi (283 MPa) | / | |
| Hardness | Typical (6061-T6): Brinell 95 HB Typical (2024-T3): Brinell 120 HB Typical (7075-T6): Brinell 150 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, Cu, Mg, Si, Zn, etc.) as defined by the alloy specification. | ASTM B211 | |
| Fabrication & Performance | Machinability | Rating (on a scale relative to 2011-T3): • 2011-T3: Excellent (100%) • 6061-T6: Good (50%) • 2024-T3: Fair (30%) • 7075-T6: Good (60%) | / |
| Weldability | Rating: • 6061-T6: Excellent (using 4043 or 5356 filler) • 2024-T3, 7075-T6: Generally considered poor (crack-sensitive). Not recommended for arc welding without specialized procedures. | AWS D1.2 | |
| Corrosion Resistance | Rating: • 6061: Excellent • 2024, 7075: Poor (unless clad with a protective layer). | / | |
| Anodizing / Coating | Can be anodized (6061 anodizes very well), powder coated, or painted. | / | |
| Stress Relieved (T651/T6511) | A critical parameter for machining. Stress-relieved bars minimize warping and distortion during and after machining, ensuring dimensional stability. | / | |
