Product Overview
Aluminium rods are solid cylindrical products widely used for precision machining, structural components, and engineering applications where strength, corrosion resistance, and dimensional stability are critical. R V Metal Corporation supplies aluminium rods in a broad range of commercial, heat-treatable, and high-strength alloys, manufactured and sourced in accordance with ASTM, EN, IS, and international standards. Available in extruded and drawn forms, our aluminium rods offer excellent machinability, consistent mechanical properties, and uniform surface finish across the length, making them suitable for CNC machining, forging, fabrication, and general engineering use.
Depending on the alloy and temper, aluminium rods provide an optimal balance of lightweight strength, corrosion resistance, thermal conductivity, and workability. Commonly supplied grades such as 6061, 6082, 7075, 2014, and 5083 cater to industries including automotive, aerospace, electrical, marine, construction, and industrial machinery. R V Metal Corporation offers aluminium rods in standard and cut-to-length sizes with full traceability, Mill Test Certificates, and export-ready packing to meet the demands of domestic and international projects.

Mechanical, Physical & Fabrication Properties
| Property Category | Parameter | Typical Value / Range | Most Relevant Alloys (from your range) | Fabrication / Performance Notes |
|---|---|---|---|---|
| Mechanical | Tensile Strength (UTS) | 90 – 610 MPa | 1100, 3003, 5052, 5083, 6061, 6063, 6082, 2014, 2024, 7075 | Highest in heat-treatable alloys (2xxx/6xxx/7xxx) in T6/T651. |
| Yield Strength (0.2% Proof) | 35 – 540 MPa | Same as above | 7xxx & 2xxx typically lead in yield; 1xxx/3xxx lowest. | |
| Elongation | 5% – 40% | 1100, 3003, 5052, 6063, 6061 | Ductility highest in O temper / low-alloy grades; reduces with strength tempers. | |
| Hardness (Brinell) | 25 – 175 HB | 2014, 2024, 6061, 6082, 7075 | Hardness increases with temper (T6/T651) and alloying (Cu/Zn/Mg). | |
| Shear Strength | 60 – 380 MPa | 6061, 6082, 2024, 7075 | Critical for fastener-type components, pins, keys, and coupling parts. | |
| Fatigue Strength (approx.) | 45 – 200 MPa | 6061, 6082, 2024, 7075 | Highly surface-finish dependent; anodizing/shot-peen can help for select uses. | |
| Impact Toughness | Good to Excellent | 5083, 5052, 6061, 6082 | 5xxx/6xxx typically tougher than high-strength 2xxx/7xxx at equivalent strength. | |
| Physical | Density | 2.66 – 2.85 g/cm³ (typical ~2.70) | All | Varies slightly with alloying (Cu/Zn increase density marginally). |
| Melting Range | 480°C – 660°C | All | Lower in high-alloy systems; important for hot work and welding. | |
| Thermal Conductivity | 120 – 235 W/m·K | 1100, 3003, 6061, 6063 | Pure/low-alloy grades conduct best; higher alloying generally reduces conductivity. | |
| Electrical Conductivity | 25 – 61 % IACS | 1100 (highest), 6063, 6061 | Use 1xxx where conductivity is critical (bus bars, electrical parts). | |
| Coefficient of Thermal Expansion | 22 – 24 ×10⁻⁶ /°C | All | Relevant for tight-tolerance machined parts and assemblies. | |
| Elastic Modulus (E) | 68 – 72 GPa | All | Similar across most Al alloys; stiffness mainly changes with section geometry. | |
| Corrosion Resistance | Moderate to Excellent | 5052, 5083, 6061, 6063 | Best in 5xxx/6xxx; 2xxx can need protection in aggressive environments. | |
| Fabrication | Machinability | Fair to Excellent | 6061 (good), 2014/2024 (good), 7075 (excellent), 1100 (fair) | High strength alloys machine well; soft grades can build-up edge without proper tooling. |
| Weldability | Good to Poor (alloy dependent) | 5052/5083/6061 (good), 2024/7075 (poor) | 2xxx & 7xxx are generally not preferred for fusion welding (cracking risk). | |
| Formability | Good to Excellent | 1100, 3003, 5052 | Best in O temper; higher strength tempers reduce formability. | |
| Hot Workability | Excellent | All | Suitable for forging, upsetting, and hot processing (process window varies). | |
| Cold Workability | Moderate to Good | 1100, 3003, 5052, 6061 | Work hardening significant in 5xxx; avoid excessive cold strain where cracking risk exists. | |
| Heat Treatability | Yes / No (by series) | Heat-treatable: 2xxx/6xxx/7xxx; Non-heat-treatable: 1xxx/3xxx/5xxx | Choose 6xxx for balanced strength + corrosion with good heat-treatment response. | |
| Anodizing Response | Good to Excellent | 6063 (best appearance), 6061 (good), 5xxx (good), 2xxx (limited) | Cu-rich alloys can produce darker/less uniform anodized finishes. | |
| Surface Finish After Machining | Good to Excellent | 6061, 6082, 7075 | Improves with sharp tooling, correct feeds/speeds, and coolant strategy. | |
| Typical Cutting Methods | Saw cutting, band saw, CNC cut, shearing (limited) | All | Specify squareness & burr control for precision applications. | |
| Joining Alternatives (when welding is poor) | Bolting, riveting, bonding, friction stir welding | 2024, 7075 | Recommended where fusion welding is not suitable. |
