Where Is 6061 Aluminum Plate Used?

From machined parts to equipment supports, 6061 aluminum plate is used across a range of industrial applications.

Machined Parts

6061 plate is a common starting material for brackets, mounting plates, housings, and other CNC-machined parts. If a part needs deep pockets or a lot of material removed, T651 is worth considering because it has been stress relieved to help limit movement during machining.

Jigs and Fixtures

Manufacturers use 6061 plate for fixture bases, locating plates, and assembly jigs. It can be drilled and tapped for mounting hardware. If flatness matters to your design, tell us the required tolerance when you send your drawing.

Machinery and Equipment

For machine panels, support plates, and automation components, 6061 offers a useful balance of strength and weight. The right thickness and temper will depend on how the finished part carries its load.

6061 Aluminum Plate FAQ

Answers to common questions about sizes, processing, certificates, and delivery.

What is the difference between 6061-T6 and 6061-T651?

6061-T6 and 6061-T651 have the same chemical composition and similar mechanical properties. The main difference is that T651 undergoes controlled stretching after heat treatment to relieve internal stress, improving dimensional stability and reducing warping during heavy CNC machining.

What sizes and thicknesses of 6061 aluminum plate do you supply?

We supply 6061 aluminum plates in thicknesses from 3 mm to 150 mm, with custom thicknesses available upon request. Standard plate sizes include 4’×8′, 5’×10′, and 1500×3000 mm, along with custom cut-to-size options.

Can you cut plates according to drawings or BOM requirements?

Yes. We provide precision saw cutting, waterjet cutting, and surface milling services based on customer drawings, dimensions, or BOM requirements to supply ready-to-machine aluminum plate blanks.

What standards and tolerances do your plates meet?

Our 6061 aluminum plates comply with ASTM B209 and EN 485 dimensional requirements. Tighter tolerances, improved flatness, and precision-machined surfaces are available for specialized applications.

How is the price of 6061 aluminum plate calculated?

Quotes are based on aluminum market conditions (such as LME/SMM), alloy temper, plate dimensions, order quantity, processing requirements, and shipping terms including FOB, CIF, and DDP.

Do you provide Mill Test Certificates (MTC)?

Yes. Every order is supplied with a certified EN 10204 3.1 Mill Test Certificate (MTC) covering material traceability, chemical composition, and mechanical test results.

How are 6061 aluminum plates packed for export?

Plates are protected with film or paper interleaving and packed on fumigated seaworthy wooden pallets with moisture-proof wrapping to ensure safe container transportation.
