Aluminum Parts for Prototypes and Production
Aluminum is one of the most common materials for CNC machining because it offers a strong balance between machinability, weight, corrosion resistance, and cost. CNC Precision Tech helps overseas buyers source custom aluminum CNC parts for electronics, robotics, industrial equipment, automotive systems, fixtures, housings, and prototype assemblies through suitable China supplier routes.
Our aluminum machining service supports engineering samples, low-volume builds, and repeat production through a coordinated China supplier network in China.
Real Aluminum CNC Machined Housings
This example shows polished aluminum housings with circular bores, drilled mounting holes, and clean machined surfaces, typical of custom enclosure and equipment parts.
Compare Aluminum Against Other CNC Materials
If your drawing could work in more than one material, compare weight, corrosion exposure, machining cost, and tolerance risk in our aluminum vs stainless steel vs titanium CNC parts guide before finalizing the RFQ.
Common Aluminum Grades
- Aluminum 6061 for general engineering and structural parts
- Aluminum 7075 for higher strength applications
- Other grades available based on project requirements

Finishing Options
Depending on your part function and appearance needs, we can review anodizing, bead blasting, machining finish, and other post-processing options during quoting.
How to Get an Aluminum CNC Quote
Send your drawing together with material grade, quantity, tolerance, finish, and target delivery date. We will review the project and provide a detailed quote within 24 hours on working days.
How to Choose an Aluminum Grade for CNC Machining
For most CNC machined aluminum parts, buyers compare 6061, 7075, 5052, and 5083. The right choice depends on strength, corrosion resistance, anodizing appearance, weldability, and budget.
Grade Best For Buyer Notes Relative Cost 6061-T6 General brackets, housings, plates, fixtures, prototypes Most common starting point; good machinability, availability, and anodizing options. Baseline 7075-T6 High-strength structural parts, aerospace-style mounts, robotics arms Higher strength than 6061 but usually higher material cost and less corrosion resistance. 1.2-1.6x 5052 Corrosion-resistant covers, panels, marine-style components Good corrosion resistance; not usually selected for very high-strength machined parts. Similar to 6061 5083 Marine, transport, and corrosion-focused parts Useful when corrosion resistance is more important than maximum strength. Project dependent

What aluminum grade is best for CNC machining?
Aluminum 6061-T6 is usually the best starting point for general CNC machined parts because it balances machinability, cost, availability, strength, and finishing options. Use 7075 when higher strength is more important than cost or corrosion resistance.
Is 6061 or 7075 better for my part?
Choose 6061 for general brackets, housings, fixtures, prototypes, and anodized parts. Choose 7075 for higher-strength structural parts such as aerospace-style mounts, robotics components, and load-bearing hardware.
Can aluminum CNC parts be anodized?
Yes. Aluminum parts can be anodized, bead blasted, polished, powder coated, or left as-machined. Cosmetic anodizing should be called out early because alloy, surface preparation, and masking can affect the final appearance.
How can I reduce aluminum CNC machining cost?
Use 6061 when possible, avoid unnecessary tight tolerances, increase internal corner radii, separate cosmetic from non-cosmetic surfaces, and provide expected repeat quantities so setup choices can be planned correctly.
What should I send for an aluminum CNC quote?
Send STEP or X_T files, a 2D drawing, material grade, quantity, tolerances, threads, surface finish, cosmetic surfaces, inspection requirements, and shipping destination.
