Aluminum Alloy Properties For CNC Machining
Selecting the right aluminum alloy determines the success of your part. Use this practical reference for CNC machining aluminum 6061 parts, 7075 aluminum machining services, 5052 aluminum sheet machining, 6063 aluminum CNC parts, 2024 aluminum alloy machining and 2017 aluminum components.
| Alloy Grade | Yield Strength | Tensile Strength | Hardness (Brinell) |
|---|---|---|---|
| 1100-H14 | ~ 110 MPa | ~ 130 MPa | ~ 32 HB |
| 2011-T3 | ~ 280 MPa | ~ 360 MPa | ~ 95 HB |
| 3003-H14 | ~ 130 MPa | ~ 160 MPa | ~ 42 HB |
| 4032-T6 | ~ 320 MPa | ~ 390 MPa | ~ 120 HB |
| 5052-H32 | ~ 180 MPa | ~ 230 MPa | ~ 60 HB |
| 6061-T6 | ~ 270 MPa | ~ 310 MPa | ~ 93 HB |
| 7075-T6 | ~ 480 MPa | ~ 560 MPa | ~ 150 HB |
* Note: Aluminum hardness is typically measured on the Brinell (HB) scale rather than Rockwell (HRC) due to its relative softness compared to steel.
International Aluminum Grade Comparison
Use our cross-reference chart to match American standards (AA/ASTM) with European (DIN/EN) and Chinese (GB) material equivalents.
| AA / ASTM (USA) | DIN / EN (Europe) | GB (China) | Key Characteristics |
|---|---|---|---|
| 6061 | AlMg1SiCu / 3.3211 | 6061 / LD30 | The industry standard. Superb weldability, highly corrosion-resistant, and responds excellently to anodizing. |
| 7075 | AlZn5.5MgCu / 3.4365 | 7075 / LC4 | One of the strongest aluminum alloys available (comparable to many steels). High fatigue strength, heavily used in aerospace. |
| 5052 | AlMg2.5 / 3.3523 | 5052 / LF2 | Exceptional corrosion resistance (especially in marine environments) and highly formable, making it great for sheet metal and structural chassis. |
Application Engineering
Application Fit Matrix
Use this matrix to match aluminum alloys with weight reduction, heat transfer, anodized appearance, or high-strength structural loading.
| Application | Recommended Material | Why This Material Works | Typical CNC Process | Finish / Risk Note |
|---|---|---|---|---|
| Aerospace Brackets & Light Frames | 7075-T6 or 6061-T6 | High strength-to-weight ratio keeps assemblies light while maintaining stiffness. | 3-axis / 5-axis milling, drilling | 7075 is less corrosion-resistant than 6061; specify anodizing or conversion coating. |
| EV Battery Housings & Heat Sinks | 6061-T6 or 6063-T5 | Good thermal conductivity and stable machining for fins, covers, and cooling plates. | High-speed milling, pocketing, tapping | Support thin fins and radius internal corners to reduce chatter. |
| Robotics End Effectors | 6061-T6 | Light, easy to machine, and strong enough for grippers and adapter plates. | Milling, boring, thread milling | Use steel inserts for threads that will be assembled repeatedly. |
| Consumer Electronics Housings | 6061-T6 or 5052 | Machines clean cosmetic surfaces and accepts anodizing. | CNC milling, engraving, chamfering | Anodized color can vary by alloy and batch; approve samples for visible parts. |
| Precision Fixtures & Plates | MIC-6 or 6061-T6 | Stable, lightweight plates reduce handling time and fixture weight. | Face milling, dowel holes, threaded features | Choose cast tooling plate when flatness is critical. |
Selection Rule
Match the grade to the part's real job first: strength, heat, wear, corrosion, insulation, transparency, or cosmetic finish.
DFM Reminder
Material choice changes tolerance risk, burr control, wall thickness, thread strategy, and finishing route.

How To Get A Better Aluminum Parts Quote
A complete RFQ helps us price custom aluminum parts accurately and flag design risks early. Include these items when possible.
1. CAD And Drawing
Send STEP or STP files plus a 2D PDF for critical tolerances, threads, flatness, surface roughness and inspection notes.
2. Material And Finish
Specify 6061, 7075, 5052, 6063, 2024 or 2017 aluminum, then define clear, black, hard anodized, bead blasted or sandblasted finish.
3. Quantity And Use
Share prototype, small batch or production quantity, mating parts, application environment and target delivery schedule.
Expert Machining Tips
While aluminum is highly machinable, its gummy nature requires specific cutting strategies. Huade engineers implement these techniques for flawless results:
- 1
Fewer Flutes for Chip Clearance
Unlike steel which uses 4+ flute end mills, aluminum should be machined using 2 or 3-flute carbide cutters. This provides larger chip valleys, preventing the material from clogging and snapping the tool.
- 2
Maximized RPM & High Feeds
Aluminum loves speed. We push our spindles to 10,000+ RPM with aggressive feed rates to effectively shear the metal and prevent built-up edge (BUE), leaving a mirror-like finish.
- 3
Strategic Coolant Usage
Because aluminum heats up and becomes sticky, using a high-lubricity coolant (or Minimum Quantity Lubrication - MQL) is critical to evacuate chips instantly and prevent the aluminum from welding itself to the cutter.
Top 3 Surface Treatments
Aluminum's natural oxide layer provides basic protection, but our in-house post-processing elevates its durability and cosmetics exponentially.
1. Type II Anodizing (Decorative)
An electrochemical process that thickens the natural oxide layer. It protects against corrosion and allows the aluminum to be dyed in vibrant, permanent colors (Black, Red, Blue, etc.).
2. Type III Hardcoat Anodizing
Creates a significantly thicker, denser oxide layer. Designed for extreme industrial applications where maximum wear resistance and dielectric (insulating) properties are mandatory.
3. Bead Blasting
A mechanical finish using fine glass beads to erase CNC tooling marks. It leaves a premium, uniform matte texture and is the industry standard pre-treatment before anodizing.
