From Custom Cross-Section to Finished Aluminum Component
Aluminum extrusion forces a heated aluminum billet through a shaped die to create a continuous profile with a consistent cross-section. The process is suitable for structural members, heat-management profiles, frames, channels, housings, guides, rails, tubes, and customized integrated shapes.
A successful extrusion project must consider alloy, temper, profile size, wall thickness, tongue ratio, hollow structure, corner radii, dimensional tolerances, straightness, twist, surface requirements, cut length, machining, joining, finishing, and final application.
- Integrated cross-sections that reduce assembly
- Continuous profiles cut to custom lengths
- Solid, hollow, and semi-hollow geometries
- Channels, tubes, rails, frames, and heat sinks
- Machined and finished extrusion components
- Prototype samples to repeat production

Custom Alloy Review
Other extrusion alloys can be evaluated according to profile geometry, mechanical requirements, finishing, and availability.
T5 Temper
A common extrusion temper used when the required combination of profile performance, straightening, and processing is suitable.
T6 Temper
Used for projects requiring increased strength after solution heat treatment and artificial aging, subject to the alloy.
Key Design Considerations for Aluminum Profiles
Good profile design improves material flow, dimensional stability, die life, surface consistency, straightness, machining, assembly, and total project cost.
| Design Element | Extrusion Consideration | Buyer Guidance |
|---|---|---|
| Wall Thickness | Large thickness changes can affect material flow, cooling, distortion, and surface | Keep walls as balanced as the function allows |
| Corner Radii | Rounded transitions improve metal flow and reduce stress concentration | Avoid unnecessary sharp internal corners |
| Hollow Sections | Hollows increase die complexity and require careful bridge and seam planning | Use enclosed cavities only where functionally valuable |
| Deep Channels | High tongue ratios can affect die strength, profile stability, and cost | Increase opening width where the design allows |
| Cosmetic Surfaces | Die lines, handling, alloy, finishing, and machining can affect appearance | Identify visible surfaces and finish standards |
| Tolerances | Depend on profile size, geometry, alloy, temper, die, straightness, and machining | Apply tight tolerances only to critical features |

What tolerances can aluminum extrusions achieve?
Achievable tolerances depend on profile size, geometry, wall thickness, alloy, temper, die design, straightness, twist, cut length, machining, and finishing. Critical requirements should be marked on the drawing.
