AEROSPACE MATERIALS
Materials for CNC Machined Aerospace Parts
Material selection plays an important role in the strength, weight, dimensional stability, and performance of aerospace components. Karry Precision works with aluminum alloys, titanium, stainless steel, and engineering plastics for drawing-based manufacturing. Final material selection depends on the part's operating environment, mechanical requirements, tolerances, and customer specifications.
| Material Family | Common Options | Why It Is Used | Typical Part Types |
|---|---|---|---|
| Aluminum | 2024, 6061, 6082, 7075 | Low weight, strong machinability, good strength-to-weight ratio | Brackets, frames, housings, structural parts |
| Titanium | Grade 2, Grade 5 | High strength-to-weight ratio and corrosion resistance | High-load hardware, precision structural parts |
| Stainless Steel | 303, 304, 316 | Strength, corrosion resistance and durability | Fittings, shafts, hardware, interfaces |
| Engineering Plastics | PEEK, POM, PTFE, PC | Low weight, insulation, low friction or chemical resistance | Insulators, guides, functional housings, fixtures |
TOLERANCE & QUALITY CONTROL
Quality Inspection for Aerospace CNC Machined Parts
Quality control for aerospace-related components begins with drawing review and inspection planning. Critical dimensions, datum relationships, geometric tolerances, and surface requirements are evaluated before machining. Depending on project requirements, inspection may include conventional measuring instruments, optical measurement, CMM verification, and project-specific dimensional reports.
- Drawing and datum review before process planning
- Incoming material and in-process dimensional checks
- CMM and conventional metrology according to feature requirements
- Project-specific dimensional reports when requested
- Final inspection before shipment
TYPICAL 5-AXIS REFERENCE
±0.02–0.05 mm
Typical precision tolerances for 5-axis machined features are approximately ±0.02–0.05 mm. Actual achievable tolerances depend on material, geometry, part size, machining strategy, and inspection requirements. Tighter dimensions require engineering review.
Do not over-tolerance the whole part
Keep the tightest tolerances on function-critical features and use practical tolerances elsewhere to improve manufacturability and control cost.
Surface Finishing for Aerospace Components
Finish requirements should define material compatibility, masking, corrosion or wear needs, cosmetic surfaces and post-finish dimensional control.
ALUMINUM
Anodizing
Corrosion and wear resistance with controlled technical appearance for aluminum components.
STAINLESS STEEL
Passivation
Supports corrosion resistance by removing free-iron contamination from compatible stainless surfaces.
MULTIPLE METALS
Bead Blasting & Polishing
Used to create a uniform texture, reduce visible tool marks or improve the final surface appearance.
From Drawing Review to Final Inspection
A clear workflow keeps machining, finishing and inspection aligned as the project moves from prototype to repeat builds.
01
Drawing Review
CAD, tolerances, datums, material, quantity and finish.
02
DFM & Planning
Tool access, workholding, distortion and inspection strategy.
03
