6063 Aluminum Parts

Architectural aluminum with a smooth finish — best for cosmetic and light-structural parts.

At a glance

Stocked condition	T5 temper
Machinability	Good (gummier than 6061)
Weldability	Weldable
Corrosion resistance	Good — excellent anodizing response
Hardening	Supplied at T5 temper
Density (nominal)	0.097 lb/in³
Food contact	Generally acceptable (often anodized)
Magnetic	No

6063 is the architectural cousin of 6061: a little softer, but with a finer surface finish off the tool and an especially even, cosmetic response to anodizing. Where the part is seen — railing hardware, lighting, display fixtures — 6063 looks better than 6061 does.

For load-bearing shafts, prefer 6061-T6; 6063-T5 gives up meaningful strength in exchange for its finish.

When to choose 6063-T5

The part is visible and finish quality is a requirement.
Anodized cosmetics must be flawless and even.
Light-structural duty — trim, standoffs, decorative pins.

Consider instead

6061 — more strength for structural parts.
2011 — faster machining for volume runs.

Typical applications

Architectural and railing hardware
Lighting and display components
Decorative standoffs and spacers
Trim pins and caps

Frequently Asked Questions

6061-T6 for strength, 6063-T5 for looks. 6063 machines to a smoother cosmetic surface and anodizes more evenly, but gives up structural strength. Load-bearing shafts should default to 6061.

Its leaner chemistry (less silicon and iron in solution) produces a more uniform oxide layer, so clear and colored anodize come out brighter and more even — the reason it dominates architectural extrusions.

For light duty — guide rollers, display turntables, hand-operated mechanisms — yes. For driven shafts under real torque, use 6061-T6 or steel.

Stocked as 6063-T5. Material and condition are paired — each grade ships in one condition optimized for our process; see all grades on the materials page.
