Popular Aluminum Round Bar Grades
6061-T6 Aluminum Round Bar — The Workhorse Alloy
6061-T6 aluminum round bar is the most commonly requested grade, known for its excellent balance of strength, corrosion resistance, and weldability. With a tensile strength of approximately 310 MPa and yield strength of 275 MPa, 6061-T6 is suitable for a wide range of structural and engineering applications. It machines well, accepts anodizing beautifully, and is widely available across all diameter ranges.
Typical applications: Structural frames, machine parts, hydraulic valves, marine fittings, electrical connectors, and general fabrication.
7075-T651 Aluminum Round Bar — Aerospace Grade Strength
7075-T651 aluminum round bar delivers the highest strength among commercial aluminum alloys, with a tensile strength of approximately 572 MPa — comparable to many steels at one-third the weight. Its primary alloying element is zinc, which provides exceptional strength but limits corrosion resistance and weldability. 7075 is the material of choice where maximum strength and minimal weight are critical.
Typical applications: Aircraft structural components, military equipment, high-stress gears and shafts, rock climbing equipment, and premium bicycle frames.
2024-T4 Aluminum Round Bar — Fatigue Resistant
2024-T4 aluminum round bar is renowned for its excellent fatigue resistance and high strength-to-weight ratio. With a tensile strength around 470 MPa, it is widely used in aircraft structures where repeated loading is expected. Its copper content provides strength but reduces corrosion resistance — cladding or anodizing is recommended for exposed applications.
Typical applications: Aircraft fuselage structures, wing tension members, truck wheels, and fatigue-critical components.
5052 & 5083 Aluminum Round Bar — Marine Grade
5052 and 5083 aluminum round bars offer the best corrosion resistance among all aluminum alloys, making them the standard choice for marine and offshore applications. Their magnesium content provides excellent saltwater resistance while maintaining good weldability and moderate strength.
Typical applications: Ship hulls, marine hardware, pressure vessels, cryogenic tanks, and chemical processing equipment.
| Alloy | Temper | Tensile (MPa) | Yield (MPa) | Corrosion Res. | Weldability | Machinability | Best For |
|---|---|---|---|---|---|---|---|
| 6061 | T6 | 310 | 275 | ★★★★ | ★★★★★ | ★★★★ | General engineering |
| 7075 | T651 | 572 | 503 | ★★ | ★★ | ★★★★★ | Aerospace / Defense |
| 2024 | T4 | 470 | 325 | ★★ | ★★ | ★★★★ | Fatigue-critical parts |
| 5052 | H32 | 230 | 195 | ★★★★★ | ★★★★★ | ★★★ | Marine / Chemical |
| 6063 | T5 | 185 | 145 | ★★★★ | ★★★★★ | ★★★ | Architectural / Extrusion |
Our aluminum round bars are trusted by engineers and fabricators for a wide array of demanding applications:
CNC Machining & Turned Parts: The excellent machinability of our round bar stock makes it perfect for producing complex, high-precision components like shafts, valves, and fittings.

FAQ
What is the difference between 6061 and 7075 aluminum round bar?
6061-T6 aluminum round bar offers excellent corrosion resistance, weldability, and moderate strength (tensile strength ~310 MPa), making it ideal for general engineering and structural applications. 7075-T651 aluminum round bar delivers significantly higher strength (tensile strength ~572 MPa) but with lower corrosion resistance and weldability, making it the preferred choice for aerospace, military, and high-stress applications.
What is the best aluminum round bar for CNC machining?
For most general purpose CNC machining projects, 6061-T6 aluminum bar is the industry standard and our most recommended grade. It offers the best balance of good strength, excellent machining properties, and cost-effectiveness. For high stress applications requiring high strength, 7075-T651 bar is the best choice, although it is more difficult to machine. We are a leading supplier of both grades.
Can you supply aluminum bars cut to specific lengths?
Yes, absolutely. As a dedicated supplier, we offer value-added precision-cutting services. We can cut our aluminum round bar stock to your exact length specifications, with tight tolerances. This service saves you production time, reduces your material scrap, and delivers components ready for your manufacturing process.
What is your minimum order quantity (MOQ) for aluminum round bar?
As a wholesale aluminum manufacturer and distributor, our standard minimum order quantity is usually 500 kg per specification. However, we strive to be your flexible partner.
