0.687 (11/16 inch) x 36 inches, 7075-T6 Aluminum Round Rod
Best for long, straight runs of 7075-T6 stock. A longer, slimmer option at 0.687″ diameter and 36″ length supports milled components, probe housings, or long shaft-like parts. The 7075-T6 designation indicates heat-treated temper for improved strength. It’s suitable for precision machining and aerospace-adjacent projects where strength-to-weight matters.
Who it’s best for: shops needing a longer straight length for turning or milling operations without wid, bulky stock. Why selected: The extended length provides more usable material per piece, reducing joints and scraps in certain builds.
Caution: Check your machine’s spindle and collet capacity to handle the 36″ length; consider support or alignment aids to prevent deflection.
LOYORTY 4PCS Square Aluminum Flat Bar, 1x2x8 Inch
Best for general-purpose plate needs. This set provides four 1x2x8 inch flat bars made from 6061 aluminum, offering good corrosion resistance and weldability.

Buying Guide: 7075 Aluminum Bar Stock Buying Considerations
- Mechanical properties: 7075 offers high strength and hardness, making it suitable for load-bearing parts and precision components. Consider temper (T6, T651) for stiffness and machinability.
- Profile type: Round rods, flat bars, and square bars each serve different applications—shafts and axles favor round rods; brackets and frames favor flat bars; modular components may use square bars.
- Size and length: Match stock length to part geometry. Longer rods reduce joints but require robust tooling and clamping. Flat bars are easy to machine but may require careful edge finishing.
- Machinability and tooling: 7075 is harder than 6061; ensure your tooling and feeds are appropriate to minimize wear and achieve accurate tolerances.
- Corrosion resistance: While 7075 has good corrosion resistance, consider protective coatings or anodizing for exposed exterior parts in harsh environments.
- Alternatives: If you need easier machining or cost savings, 6061 flat bars offer good performance for less demanding applications, while still providing solid fabrication properties.
Frequently Asked Questions
- What is 7075 aluminum best used for? Answer: High-strength parts and components that require rigidity, such as shafts, structural brackets, or aerospace-adjacent fixtures.
