6061 / 6061-T6511 Aluminum

Alloy 6061 is a heat-treatable aluminum alloy. It is known for its excellent strength and corrosion resistance. Alloy 6061 is a more machinable aluminum and is the workhorse of heat-treated alloys. It is often used in various structural and fabrication applications. It is worth noting that long-term exposure to outside elements without painting or applying a clear coat finish will result in the material oxidizing (developing a white chalky surface).

Alloy 6061-T6511 is essentially the same as 6061-T651. The "T6511" designation is often used to indicate that the material meets specific industry standards for flatness and straightness. For extruded rod and bar shapes, the T6511 temper is also stress-relieved, but an applied straightening process ensures the bar is as straight as possible after extruding. Like 6061-T651, it offers high mechanical strength, stress corrosion resistance, and formability. It is commonly used in applications where precise flatness and straightness are required, such as in precision machinery and equipment.

Characteristics of alloy 6061:

Machinability = Good
Corrosion Resistance = Good
Weldability = Excellent
Bending/Forming = Fair
Magnetic = No
Heat Treatable = Yes

Common applications of alloy 6061:

• Aerospace: Aircraft components, including fuselages, wings, and structural parts.
• Automotive: Wheels, frames, suspension components, and engine parts.
• Structural applications.
• Production of sailboat, canoe, truck, and bus bodies.
• Scaffolding and transmission towers.
• Furniture.
• Marine fittings, hardware, boat hulls, and masts.
• Chemical equipment and hardware.
• Bike frames.

Finishes

What is a mill finish?
Mill finish means that items come to us exactly as they are finished at the mill. All materials can have some surface scuffs and scratches and may have a dull or matte finish.

Same-Day Shipping
We strive to ship the same business day if we receive your order by 12:00pm Central Time.*Please keep reading to learn more about our order processing and shipping policies.

Order Processing:
*Most orders are processed and shipped within 1 business day. However, if your order absolutely, positively needs to ship the same business day, give us a call at (812) 429-1634 so we can expedite the order processing. Select orders may require additional processing time based on their size, cutting method, and quantity. Unlike typical online orders that are pre-boxed and ready to go, custom-cut metals are processed from mill sizes and custom-packaged per order. Cut2Size may divide the shipment into separate packages to ensure each item is properly secured and protected. We take exceptional care to ensure every order meets our customers' expectations for accuracy, quality, and secure packaging to arrive undamaged.
