Aerospace Materials Comparison
Selecting the right material for aerospace components requires balancing weight, strength, and temperature resistance. Our experience spans various high-performance materials:
| Material (E) | Properties (A) | Applications (V) |
|---|---|---|
| Titanium Alloys | Exceptional strength-to-weight ratio, corrosion resistance, temperature stability to 1,000°F | Engine components, structural frames, landing gear |
| Aluminum Alloys | Lightweight, good machinability, excellent thermal conductivity | Fuselage components, wing structures, interior fittings |
| Inconel | Superior heat resistance up to 2,200°F, excellent strength retention at high temperatures | Turbine blades, exhaust systems, combustion chambers |
| High-Temperature Composites | Tailored properties, very lightweight, high stiffness | Interior components, non-load bearing structures |
When comparing titanium and aluminum for aerospace applications, engineers must consider the specific requirements of each component. Titanium offers superior strength but at higher cost, while aluminum provides excellent value for less demanding applications.

Additional standard treatments include:
- Anodizing: Improves corrosion resistance for aluminum components
- Chemical film: Protects electrical contacts from oxidation
- Peening: Strengthens surfaces to prevent fatigue cracks
Aerospace CNC Machining: Clamping Methods
Proper clamping ensures stability and precision in aerospace CNC machining. At ZHXING, we use various methods based on part size, shape, and material.
Vise Clamping
Vise clamping works well for smaller aerospace parts. We use:
- Minimum 10 mm clamping height for secure grip.
- Processing height slightly above vise plane.
- Ideal for brackets and housings.
Splint Clamping
Splint clamping secures thin panels and medium-to-large components. Our approach:
- ⬤Fix splint to worktable
- ⬤Lock workpiece with screws
- ⬤Supports high-force machining of strong aerospace materials
Code Iron Clamping
For large workpieces with low clamping height, we use code iron clamping:
- ⬤Clamp corners first, then sides
- ⬤Ensures accuracy for oversized parts
- ⬤Suitable for frames and wing sections
Tool Clamping
We prevent tool movement during machining with these guidelines:
- ⬤30 mm minimum clamping length for tools over 10 mm diameter
- ⬤20 mm minimum for smaller tools
- ⬤Reduces vibration and collision risk
Vacuum Clamping
Vacuum clamping offers unique benefits for certain aerospace parts:
- ⬤Ideal for flat or slightly curved workpieces
- ⬤Prevents mechanical marks on delicate surfaces
- ⬤Useful for thin sheets and composite materials

What Our Clients Say
Advanced CNC Capabilities for Aerospace
While standard 3-axis CNC machining serves many industries effectively, aerospace components often require more advanced capabilities:
3-Axis vs. 4-Axis vs. 5-Axis Comparison
- 3-axis machining: Suitable for simple aerospace brackets and flat components
- 4-axis machining: Enables cylinder-shaped components like fuel system parts
- 5-axis machining: Essential for complex contoured surfaces like turbine blades and wing structures
Our 5-axis capabilities allow us to create complex aerospace geometries in a single setup, reducing production time while maintaining aerospace-grade tolerances of ±0.003″ or tighter.

FAQs About Medical
1. How do you ensure biocompatibility for implantable medical components?
Biocompatibility for implantable components begins with certified medical-grade materials that comply with ASTM and ISO standards for specific implant applications. We maintain strict material segregation protocols to prevent cross-contamination and implement specialized cleaning procedures to remove machining oils and contaminants. Our surface finishing processes create the appropriate surface characteristics for tissue interaction, while our documentation system provides complete material traceability from raw stock to finished component for regulatory submission.
2. What validation documentation can you provide for medical components?
We provide comprehensive validation documentation packages that include material certificates, dimensional inspection reports, and process validation records. These packages contain First Article Inspection (FAI) reports with detailed measurements of all critical dimensions, material certifications with chemical composition and mechanical properties, and process validation evidence showing our capability to consistently produce components within specification. This documentation supports FDA submissions, technical files for CE marking, and other regulatory requirements while providing verification of component quality.
3. How do you handle design changes during medical component development?
Design changes during development follow our controlled change management process that evaluates the impact on functionality, manufacturability, and regulatory compliance. Our engineering team collaborates with clients to understand the purpose of changes, then performs DFM analysis to optimize the revised design for production. We create revised manufacturing documentation, update inspection protocols, and produce validation samples for approval before implementing the changes. This structured approach ensures design iterations improve the component while maintaining regulatory compliance and documenting all modifications for traceability.
