Cut2Size offers two popular forms of aluminum channel, each with its distinct features:

The aluminum channel in alloy 6061-T6 is known as American Standard or Structural Aluminum “C” channel. It is an extruded aluminum product with tapered legs (the thickness of the legs varies), so the inside dimension between the legs gets smaller as you approach the bottom of the channel. It is typically intended for structural applications where strength is required.

The aluminum channel in alloy 6063-T52 is known as Aluminum Association or Architectural Aluminum Trim channel. It is an extruded aluminum product with straight legs. It has sharp, square corners on the inside and outside. This item is ideal for many trim applications, frame work, bracing, brackets, trailers, and more.

Both alloys are extruded from 6000 series aluminum. This series of aluminum yields a harder material with good strength. To measure a channel, take the width of the channels, the height of its flange (legs), and its web (thickness of the material between the two flanges). Cut2Size Metals will pack your aluminum channel safely in our tailored, high-quality packaging with same-day shipping on most orders. Order full-length channel or custom-cut lengths today.

Standard sizes & custom cuts: Stock channel is 16 or 25 ft. and can be custom cut to any length.
Custom-cut tolerance: +/- 1/16". If you need a tighter tolerance, call us!
Volume discounts: Unit prices drop on most custom-cut products when you increase the quantities.

Cut2Size Metals provides general properties and typical uses for the alloys we carry, however, the suitability of a material for any application or the manner of its use is the sole responsibility of the customer. If you have specific requirements for your application, we strongly suggest contacting us before purchasing.

Aluminum 6061 & 6063 Alloy Characteristics, Applications & Finishes

6061 / 6061-T6 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-T6 is a temper condition indicating that it has been heat-treated and artificially aged, which increases the strength of the material. The "-T6" temper provides improved mechanical properties, including higher tensile strength and hardness. It maintains good corrosion resistance and retains its formability. This temper is commonly used in aerospace, automotive, and structural applications.

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.

6063 / 6063-T52 Aluminum

Alloy 6063 is a heat-treatable aluminum alloy. It is a softer, more formable aluminum. Alloy 6063 offers good corrosion resistance. It is often used in architectural and structural applications. It is especially great in projects where the primary concern is for the final product to be lightweight and corrosion-resistant.

Alloy 6063-T52 is a temper condition indicating that it has been stress-relieved after extrusion. The "-T52" temper provides mechanical properties suitable for cold forming. It offers good formability and corrosion resistance. This temper is typically used in applications where cold forming is required.

Characteristics of alloy 6063:

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

Common applications of alloy 6063:

Architectural applications.
Furniture: Frames, chairs, tables, and shelving.
Automotive trim: Moldings and bumpers.
Lighting fixtures and LED heat sinks.
Railings and balustrades.
Signage frames and structural components.
Solar frames.
Luggage racks.
Irrigation tubing.

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.
