Buying Guide

Choose the right alloy

Select 6061 aluminum for a strong, weldable option; other alloys may prioritize machinability or corrosion resistance

Pick the appropriate shape

Round, flat, and straight-edge profiles serve different tasks—round for shafts, flat for bracing, and straight edges for layout and inspection

Check dimensions and tolerances

Confirm length, cross-section, and any specified tolerances to avoid unnecessary cuts or rework for your project

Consider finish and coating

Anodized finishes resist surface wear and improve contrast for layout tools, while raw mill finish is easier to machine and bond

Assess value by pack size

Single bars suit one-off jobs; multi-packs can offer better per-piece value for recurring fabrication needs
