Aluminum Design
Design guidance for engineers building aluminum parts with CNCALPARTS. From alloy and temper selection to wall thickness, thread design, anodizing preparation, and cosmetic surfaces — these references are built around one material, so the advice stays practical on the shop floor.
- Material Focus
- Aluminum Only
- Precision
- Down to ±0.01 mm
- Stage
- Prototype to Production
What this library covers
- 01 Alloy and temper choices for housings, brackets, heat sinks, and precision components.
- 02 Geometry rules for wall thickness, deep pockets, threads, and thin-wall stability.
- 03 Anodizing and cosmetic surface preparation before a part reaches the machine.
We machine aluminum. Only aluminum.
Focused expertise means better tooling, workholding, deformation control, and finish consistency.
Design for Aluminum, Not for Every Material
Aluminum behaves differently from steel, stainless, brass, or titanium. It cuts fast, moves under heat, distorts at thin sections, and reacts in specific ways during anodizing. Design decisions that work well for one metal can create scrap in another.
Because CNCALPARTS works exclusively in aluminum, the guidance in this library reflects real production experience — tooling choices, cutting parameters, workholding strategy, deformation control, surface finish, and anodizing preparation.
Alloy & Temper
Match 6061, 7075, 6082, 2024, 5052, and other grades to strength, machinability, finish, and anodizing requirements.
Geometry & Tolerances
Plan wall thickness, holes, threads, flatness, and parallelism so parts stay stable from prototype through repeat production.
Finish & Anodizing
Prepare cosmetic surfaces, bead blasting, brushing, polishing, and anodizing so appearance and dimensions both hold.
How We Support Design Decisions
Send a STEP file and a PDF drawing, and we review tolerances, critical dimensions, surface requirements, and inspection needs before machining begins.
Discuss Your DesignManufacturability Review
We flag thin walls, deep pockets, tight bores, and cosmetic risk areas early, before tooling and setup time are committed.
Anodizing Preparation
Dimension allowances, surface condition, and masking considerations are planned so anodized parts meet both appearance and tolerance targets.
Inspection & Reporting
CMMs, height gauges, micrometers, calipers, thread gauges, and surface roughness testers support dimensional inspection and first article reports.
Prototype to Production
From 1–10 pcs prototypes to 500+ pcs batch runs, setups, fixtures, and inspection plans stay consistent across volumes.
Aluminum Design Articles
Practical references for engineers designing aluminum CNC parts — alloy and temper selection, wall thickness guidelines, thread design, anodizing design, and cosmetic surface planning.
