Choose it when
Default choice for structural and enclosure parts: the best balance of strength, machinability, cost and anodizing response. If in doubt, start here.
Look elsewhere when
Step up to 7075 when strength or fatigue governs the design; pick 6063 for display-grade anodized cosmetics; pick 5052/5083 for welded or marine assemblies.
Compatible finishes
As-Machined
The baseline finish: straight off the machine, fastest and cheapest.
Anodizing Type II (Clear)
The standard aluminum finish: hard, clear oxide that keeps the metallic look.
Anodizing Type II (Dyed)
Color that cannot peel: dye locked inside the part’s own oxide layer.
Hardcoat Anodizing Type III
Wear armor for aluminum: an oxide layer as hard as tool steel.
Chromate Conversion (Alodine / Chem Film)
Corrosion protection that stays conductive — the EMI-grounding finish for aluminum.
Bead Blasting
The uniform matte look: erases tool marks, hides fingerprints, preps perfect anodizing.
Brushed Finish
The appliance-grade look: directional satin grain on panels, bezels and show faces.
Powder Coating
Baked-on polymer armor: any RAL color, outdoor-proof, the toughest cosmetic coating.
Wet Painting
Any color, any gloss, any substrate: the flexible coat for plastics and appearance prototypes.
Vibratory Tumbling
Batch deburring by the bowl-full: every edge broken, every burr gone, at volume prices.
Laser Marking
Permanent identification with zero dimensional change: serials, logos and codes burned in, not stuck on.
Typical applications
- Robot frames and structural brackets
- Electronics enclosures and heat sinks
- Drone arms and motor mounts
- Fixtures and automation tooling
