Why Aluminum Angle?
Lightweight Strength
High stiffness-to-weight for frames, guards, shelves, and architectural trims.
Finish Flexibility
Mill, brushed, anodized (clear/black), or powder-coated for aesthetics and durability.
Fabrication Friendly
Easy cutting, drilling, and assembly. 6061 weldable; 6063 extrudes clean details.
6061 vs 6063 — Which Angle Should I Choose?
| Alloy/Temper | Strength | Weldability | Surface/Anodize | Typical Uses |
|---|---|---|---|---|
| 6061-T6/T6511 | Higher structural strength | Good | Good | Machine frames, brackets, vehicle & marine structures |
| 6063-T5/T52/T6/T66 | Medium strength | Good | Excellent (premium anodize) | Architectural trims, railing, displays, interior build-outs |

Aluminum Angle Weight Calculator
Estimate linear weight. Density defaults to 2.70 g/cm³. For architectural 6063 you can keep this value; for other alloys adjust as needed.
Method
Approximate area A ≈ (A×t) + (B×t) − t² − corner adjustments.
If inside radius r > 0, subtract the overlap triangle and add fillet sector.
Convert mm→cm, Volume V = A × length, Mass = V × density.
A≈(A×t + B×t − t²) ; Volume=A×L; Mass=V×ρ with ρ=2.7 g/cm³.

Frequently Asked Questions (FAQs)
Do you supply sharp-corner angles?
Standard extrusions include a small inside radius. For sharp edges, machining or special tooling may be required—share your print.
What tolerance can I expect?
Extruded angle dimensional and straightness tolerances follow ASTM B221; we’ll confirm achievable limits per size and temper.
Can you notch, slot, or pre-drill?
Yes. We offer CNC and jigged fabrication to speed your assembly while controlling burr and flatness.
Which finish is best outdoors?
Clear/black anodize or powder coat. 6063 provides a more uniform anodized appearance for visible trims.
