FAQs About Aluminum Round Bars

What’s the best aluminum round bar grade for aerospace?

6061 T6 is the aerospace standard. It offers excellent strength-to-weight ratio and machinability. For higher strength, 2024 and 7075 are also used but 6061 T6 is most common.

Can you bend aluminum round bars?

Yes, depending on the grade and diameter. 6061 T4 is easier to bend than T6. 3003 aluminum bends to tighter radii. See our complete bending guide →

What’s the difference between T6 and H32 temper?

T6 is heat-treated (artificial aging) for high strength. H32 is work-hardened (cold rolled) for ductility. T6 grades are stronger; H32 is more formable.

Can you supply bright drawn finish?

Yes. Bright drawn finish is standard for machining applications. Polished and ground finishes also available.

What are your delivery times?

Stock sizes: 5-10 business days. Custom diameters: 2-4 weeks depending on size and quantity.

Do you cut to length?

Yes. We provide precision cutting services. Additional charges apply—submit your dimensions for a quote.

Is third-party inspection available?

Yes. SGS, Bureau Veritas, TUV inspection available. Specify at order time.

What’s your MOQ?

We accept orders of all sizes. Contact sales for your specific requirements.
