YOUR MATERIAL DECISION
6063 Aluminum Properties for Your Finished Profile
For custom 6063 aluminum parts, start with the section your assembly needs. 6063 is a candidate for hollow profiles, visible housings and finned sections where extrusion and finishing matter together.
Your load, wall layout, straightness, mating features and environment still control the choice. A material name does not define a finished-part tolerance or thermal result.
Repeat the section
Review die feasibility and cut length.
Machine the interfaces
Locate bores, slots and end faces.
Protect the appearance
Agree visible faces and packaging.
COMPOSITION + CONDITION
6063-T5 vs 6063-T6: Specify the Condition You Need
Keep composition, temper and the applicable product standard on the same purchase order.
6063 T5 Aluminum
Cooled after an elevated-temperature shaping process and artificially aged. For 6063-T5 aluminum parts, confirm the supplied section and its material record.
6063 T6 Aluminum
Solution heat-treated and artificially aged. For 6063-T6 aluminum parts, define the required final condition, including effects of later welding or heat.
6063 Chemical Composition Limits
| Element | Weight % | Element | Weight % |
|---|---|---|---|
| Silicon (Si) | 0.20–0.60 | Magnesium (Mg) | 0.45–0.90 |
| Iron (Fe) | ≤0.35 | Copper (Cu) | ≤0.10 |
| Manganese (Mn) | ≤0.10 | Chromium (Cr) | ≤0.10 |
| Zinc (Zn) | ≤0.10 | Titanium (Ti) | ≤0.10 |
| Other: each | ≤0.05 | Other: total | ≤0.15 |
| Aluminum (Al) | Remainder | Basis | Maximum unless a range is shown |
Weight percentages. “Remainder” identifies the aluminum balance; it is not a separate purity guarantee. Confirm the applicable material specification and lot certificate.
Selected Extruded Strength Limits
| Condition / test-section thickness | UTS min. | 0.2% yield min. | Elongation min. |
|---|---|---|---|
| T5, ≤12.50 mm | 150 MPa | 110 MPa | 8% |
| T6, ≤3.20 mm | 205 MPa | 170 MPa | 8% |
These are source minimum levels for the listed test-section ranges, not universal typical values. Test-section thickness determines the applicable limits. Elongation is in 2 inches or 4× specimen diameter; the source exempts some small/thin shapes from elongation testing.
Thermal, electrical and physical reference
| Property / condition | Reference value |
|---|---|
| Typical thermal conductivity, 25 °C — T5 / T6 | 209 / 201 W/(m·K) |
| Typical electrical conductivity, 20 °C — T5 / T6 | 55 / 53% IACS |
| Density | 0.097 lb/in³ |
| Melting range | 1140–1210 °F |
| Average linear thermal expansion, 68–212 °F | 13.0 × 10⁻⁶ in/(in·°F) |
Conductivity values are typical, not a heat-sink rating or finished-part guarantee. Temperature, geometry and test conditions matter.

Resolve 8 Profile Risks Before Machining
Use the topic that controls your assembly. These review checks are tailored to your drawing.
01
Choose the Reference Before You Clamp
Use stable assembly references for 6063 aluminum secondary machining. Distinguish an extruded face from a machined datum and agree how the part is supported.
- Name the inspection datum scheme.
- Keep mating features related on the finished drawing.
02
Protect Thin Sections During Machining
For 6063 aluminum profile milling, review wall stiffness, clamp pressure and cutter reach before freezing the geometry.
- Support hollow sections near the cut.
- Review chatter and movement through the setup.
03
Separate Global Shape from Local Features
Cut length, straightness and twist can affect fixture seating even when a local hole is correctly machined.
- Specify the measurement length and condition.
- Do not treat raw-profile tolerance as the finished-feature tolerance.
04
Give the Tool a Feasible Path
Review long slots, internal corner radii and access through a hollow section.
- Identify features that can be machined from an end.
- Resolve inaccessible internal operations before release.
05
Locate Threads Around the Actual Wall
Specify thread depth, engagement and breakout where a hole intersects a hollow profile.
- Check the usable wall and mating screw.
- Define any insert and assembly requirement.
06
Preserve the Thermal Interface
A 6063 aluminum heat sink needs the contact geometry and operating conditions, as well as a material selection.
- Specify flatness or surface requirements only where needed.
- Review airflow, heat input and thermal-interface material.
07
Plan Racking and Visible Surfaces
Identify exposed faces before choosing clamps, rack contacts, marks or packing materials.
- Approve color and texture on a representative sample.
- Locate permissible handling or racking marks.
08
Check the Part After the Specified Finish
Coating, sealing and masking belong in the same dimensional decision as the machined feature.
- State which sizes apply after finishing.
- Define masked threads, bores and contact surfaces.

Illustrative finish concept; color does not identify alloy or temper.
3 Application Reviews for Your 6063 Profile
6063 Aluminum Heat Sink
For your power-electronics profile, review fin geometry, base thickness, airflow and the thermal interface. The alloy designation alone does not establish a heat-dissipation rating.
6063 Aluminum Extruded Housing
For a 6063 aluminum electronic enclosure, define board guides, connector ports, covers and mounting faces. IP, EMC or other product ratings require their own design and verification.
6063 Aluminum LED Heat Sink
Review the LED mounting bed, installation space, cooling path and operating conditions. Mark the contact face and finish requirements before machining.
Illustrative component scenarios, not customer cases, certified assemblies or tested thermal results.

Your Questions Before Ordering 6063 Aluminum Parts
Is 6063 aluminum good for CNC machining?
6063 aluminum machined parts can be reviewed for suitable pockets, slots, holes and end features. Feasibility depends on temper, section support, access, removal volume and finished tolerances. Compare the complete route with an extrusion-led or stock-machining alternative.
What is the difference between 6063-T5 vs 6063-T6?
T5 is cooled from an elevated-temperature shaping process and artificially aged; T6 is solution heat-treated and artificially aged. Confirm the required product form, specification and material certificate. The temper code alone does not establish one strength value for every section.
Can 6063 aluminum be anodized?
6063 is commonly considered for anodized profiles. Specify the process, thickness, sealing, color reference and masked areas together. Surface preparation and material condition affect appearance; approve a representative sample.
Is 6063 aluminum good for heat sinks?
It is a candidate for extruded fins and bases. Thermal performance depends on heat input, fin and base geometry, airflow, mounting and the thermal interface. Use a design calculation or test for the actual operating condition.
What files are needed for a custom 6063 parts quote?
Supply the section drawing and CAD, controlled finished drawing, temper and specification, cut length and quantities, critical dimensions, finish, documentation and delivery requirements. State whether an existing section or a new extrusion die is required.
What tolerances can machined 6063 extrusions achieve?
Review the actual drawing. Separate raw-profile dimensional, straightness and twist requirements from local machined-feature tolerances. Geometry, support, length, finish and measurement condition determine feasibility; no single tolerance applies to every extrusion.
What should you ask a 6063 aluminum parts manufacturer?
Ask how the starting section and temper are verified, which revision controls machining, which dimensions apply after finishing and what material, inspection and packing records are supplied. Confirm substitutions and exceptions before manufacture.
How do you review a 6063 aluminum enclosure manufacturer?
Compare section feasibility, board and cover interfaces, connector machining, visible finish and assembly checks. A material choice does not automatically provide IP protection, EMC performance or a qualified product rating.
Do custom 6063 aluminum profiles need a new die?
An available section may suit your requirements; a unique cross-section may need a new die. Review section geometry, die scope, ownership, trial quantities and repeat demand. Die cost and minimum order terms are project-specific.
Can you weld 6063 aluminum parts?
Suitable joining procedures can be reviewed, but welding can reduce strength in heat-affected regions of heat-treated material. Confirm the joint, filler, required final properties, distortion and surface treatment with the design authority.
