How to Manufacture Round Aluminum Extrusions?

How to manufacture round aluminum extrusions?

Aluminum extrusions exhibit exceptional formability, enabling the fabrication of curved frames and structures. Common industrial bending methods for aluminum profiles include:

  • Ram/push Bending: A semicircular ram tool presses the extrusion to create the bend angle
  • Rotary Draw Bending: Extrusion wrapped around a mandrel produces very tight radius bends
  • Three-Roller Bending: Rollers control extrusion curving through mechanical leverage
  • Compression Bending: Localized application of force induces controlled bending
  • Stretch Bending: Tensile loads generate bending through elongation along the outer profile arc
  • Minor bowing or warping of aluminum framing can often be corrected through careful straightening by:
  • Applying localized heat to soften the aluminum along the distortion
  • Slowly exerting force to pull against the bow/warp careful to avoid over-stressing
  • Smoothing deformations gradually while heating/cooling to prevent cracking

Kinked or creased sections require replacement since aluminum cannot be repaired once deformed plastically.

When appropriately formed, aluminum profile framing achieves reliable structural integrity. The bendability of aluminum extrusions enables the creation of specialized frames combining straight sections, curves, and custom shapes.

What Are Round Aluminum Extrusions?

Circular aluminum extrusions provide lightweight and corrosion-resistant round framing solutions. Aluminum's extrudability allows the cost-effective production of custom round profiles sized and structured per application requirements.

Round aluminum framing leverages the benefits of aluminum alloy properties including high strength-to-weight ratios, dimensional stability across temperature fluctuations, and resilience in humid and salty environments. Anodized or powder-coated finishes further enhance appearance and weather resistance.

Potential applications for circular aluminum extrusion framing span transportation equipment like bicycles and carts, mechanical systems including robotics and automation equipment, retail display stands, and specialized structural components in harsh marine settings. Customized diameter, thickness, and alloy composition produce rounded aluminum frames to satisfy mechanical and reliability criteria at reasonable manufacturing costs.

The consistency and precision inherent in the aluminum extrusion process enable round profiles that exhibit consistent tolerance and performance quality along the linear length. Curved aluminum framing sections can be bent post-extrusion where required.

Why Use Round Aluminum Extrusions?

Circular aluminum extrusions provide lightweight, corrosion-resistant round framing ideal for diverse applications:

Mounting Components: The low-profile round shape enables adjustable positioning in space-constrained areas.

Light & Medium Duty Structures: Aluminum's strength-to-weight benefits static and dynamic loading for railings, robotics, displays, etc.

Material Handling: Tubular aluminum used as cross ties in industrial racking systems must sustain heavy shear and tensile stresses.

Benefits driving adoption of round aluminum extrusions:

  • High strength-to-weight ratio improves service life under loading
  • Resilient against harsh outdoor and chemical exposures
  • More cost-effective than round steel tubing or wood materials
  • Custom diameters and alloy grades available
  • Excellent conductivity of heat and electricity
  • Non-sparking behavior improves safety

The consistency and precision inherent in the aluminum extrusion process enable light, strong, and corrosion-resistant round framing suitable for manufacturing processes and equipment exposed to demanding conditions.

How Do Round Aluminum Extrusions Work?

Aluminum extrusion involves forcing heated aluminum alloy billets through a die to create long profiles with customized cross-sections. The process consists of:

1. Heating aluminum round stock called billets to 500°C-930°C depending on the alloy

2. Using extreme hydraulic pressure to push the softened aluminum through a hardened steel die

3. Cooling and straightening the extruded profile

The die forms the aluminum into virtually any shape, enabling innovative profile designs. However, sharper corners incur higher stresses. Normal corner radii range from 0.4 mm to 1.0 mm, with 0.2mm being the practical minimum.

Hollow and enclosed shapes utilize porthole dies, composed of two interlocking parts:

  • Mandrel: Forms the interior profile surface
  • Cap: Forms the exterior profile surface

The versatility of aluminum extrusions stems from this ability to customize linear framing geometries and dimensions to achieve required strength, functionality, weight, and aesthetic properties at reasonable cost across countless commercial and industrial applications.

People May Ask

Is A Larger Or Smaller Bend Radius Preferable?

Use the biggest radius that is practical because anything less can quickly result in failure. Nonetheless, cables should also not be bent sharply. This implies that the support for cables used in moving applications should prevent the cables from kinking as a result of machine movement.7 Jan. 2022

How Do You Determine The Length of A Bend?

Bend Allowance = Angle * (PI / 180) * (Radius + K-factor * Thickness) is the formula (see Bending Formulas). After entering our figures, we get the following: Bend Allowance = 90 * (PI / 180) * (0.125 + 0.42 * 0.036) = 0.2200999813105009. Use the Bend Calculator if you don't have a calculator on hand.

Can You Roll 6061 Aluminum?

In response, 6061-T6 aluminum is tempered and well-known for being difficult to bend. When it comes to bending, it is usually preferable to bend these components when they are annealed and then temper them to the proper state.

Describe A 3030 Round.

The 30-30 is essentially the premier North American deer cartridge. It was developed as the first small-bore, sporting rifle cartridge using smokeless powder. The name of this bullet, which is.30 caliber and contains 30 grains of smokeless powder, is a combination of the cartridge size and shape.

What Are The Details of Round 6061-T6 Bar?

The 6061-T6 aluminum rod has a minimum yield strength of 145MPa and a minimum tensile strength of 310MPa, with a density of 2.7 grams per cubic centimeter. Compared to most stainless steels, this is almost three times lower.

What Distinguishes Coextrusion from Extrusion?

Co-extrusion and extrusion have different purposes.

In a typical extrusion process, solid plastic pellets are gravity fed into a forming mechanism where they are melted and fed into a die by jacketed compression screws. Coextrusion, in contrast, uses several extruders to create layered or enclosed pieces.

What Distinguishes The Numbers 1060 And 6061?

The composition of 1060 and 6061 aluminum is their primary distinction. Aluminum 6061 contains 96.1% aluminum, compared to aluminum 1060's 99.6% aluminum content. Iron and silicon are the only surviving components in 1060 aluminum, whereas copper, magnesium, and chromium are the only remaining elements in 6061 aluminum.

Does 6061 Cost Less Than 5052?

Generally speaking, 5052 is less expensive than 6061. In conclusion, some aluminum alloys, particularly 5052-H32, are great choices for NEMA approved electrical enclosures, especially if heat dissipation is a concern or if the enclosure will be utilized outdoors.

What Does Aluminum T651 Mean?

The -T651 marking indicates that the aluminum mill stretched or permanently set the extrusion by 1% to 3% in order to reduce some of the remaining stresses. Now that we can machine it, it ought to deform less. For plates, common requirements include AMS-QQ-A-250/11 and ASTM-B209.

What Distinguishes 6061-T6 Aluminum from 6063-T5 Aluminum?

Magnesium and silicon are the alloying ingredients that play a significant role in the creation of AA 6061-T6. Another aluminum alloy with the same alloying components, silicon and magnesium, is AA 6063-T5.

I received the 400mm rails and used my cast iron table saw bed to confirm their straightness; they are all absolutely straight. The components are devoid of burrs, clean, and scratches, and the anodization is uniform. Although they won't be sufficient on their own, the right-angle parts that employ set screws to brace the rails at 90 degree angles could use some reinforcing. However, they will hold them during initial alignment. bubble wrap first, then a cardboard box during packaging. Perfect for my x-y gantry project.


I'm currently constructing a new 3D printer, and these 2020 extrusions are ideal. With the exception of not being internally threaded like some of the other v slot extrusions I've made with, they are similar to the majority of other v slot extrusions. It's not a huge concern because I can create my own threads already. The fact that corner brackets were included in the shipment makes a big difference because it means I won't need to buy as many parts later. The size matches the description exactly, and everything else appears just like in the provided photos.


These are mounted on 5' x 5' keyboard risers that I constructed for my church. Three years ago, I purchased a similar item from this vendor for a drum riser, but I used thumb wheel lifters instead, and they worked perfectly. I purchased these for the two new risers since I think the ratchet mechanism will be more user-friendly. These risers appeared to function flawlessly when I sent them three days ago. robust and incredibly smooth rolling. I don't think there will be any problems with these based on the casters I've previously bought, but I will update this post if there are.

How can I help you? :)
