Aerospace components operate in environments where failure is not an option. Every dimension, material, and process must be controlled, documented, and traceable. The machining suppliers in Rapid Manufacturing's network understand these requirements — from the moment raw material arrives with its mill certificate through to final inspection and CoC sign-off.
Whether you need a single prototype bracket in 7075-T6 aluminium, a batch of Ti-6Al-4V structural fittings for a UAV program, or high-temperature Inconel 718 components for engine testing, our network can handle the material, process, and documentation requirements your program demands.
Typical aerospace CNC capabilities we source include: 5-axis milling for complex monolithic structures, CNC turning for shafts and bushings, wire EDM for tight-tolerance profiles in hardened materials, surface grinding for sealing faces and precision flats, and CMM inspection with full FAI reporting.
Aerospace Materials
Aluminium 7075-T6
Primary structural components, ribs, spars, brackets
Highest strength aluminium alloy — strength-to-weight ratio comparable to many steels
Aluminium 2024-T3
Fuselage skin, wing structures, fatigue-critical parts
Excellent fatigue resistance — the original aerospace aluminium alloy
Titanium Ti-6Al-4V (Grade 5)
High-stress structural parts, fasteners, fittings, landing gear
Best strength-to-weight ratio of any metal — corrosion resistant, biocompatible
Inconel 718
Engine components, exhaust systems, high-temperature parts
Retains strength to 700°C — essential for turbine and engine environments
Inconel 625
Exhaust ducting, thrust reversers, heat shields
Superior corrosion and oxidation resistance at elevated temperatures
17-4PH Stainless Steel
High-strength fasteners, fittings, actuator components
Precipitation-hardened — combines high strength with good corrosion resistance
15-5PH Stainless Steel
Valve bodies, fittings, structural parts requiring high toughness
Better transverse toughness than 17-4PH — preferred for critical structural parts
Aluminium 6061-T6
Secondary structures, brackets, non-flight-critical components
Best machinability of structural aluminiums — cost-effective for non-critical parts

Aerospace CNC Machining FAQ
What CNC machining processes are used in aerospace?
Aerospace components typically require 5-axis CNC milling (for complex geometries in a single setup), CNC turning (for shafts, bushings, and rotational parts), wire EDM (for tight-tolerance features in hardened materials), surface grinding (for flatness and parallelism requirements), and coordinate measuring machine (CMM) inspection. The combination depends on the component geometry, material, and tolerance requirements.
What materials are most common in aerospace CNC machining?
The most common aerospace materials are aluminium alloys (7075-T6 and 2024-T3 for structural components, 6061-T6 for less critical parts), titanium (Ti-6Al-4V / Grade 5 for high-strength, low-weight structural parts and fasteners), nickel superalloys (Inconel 718 and 625 for high-temperature engine components), and stainless steel (15-5PH and 17-4PH for high-strength fasteners and fittings). Material traceability — certifications, heat lot numbers, and material test reports — is typically required for all aerospace work.
What tolerances are achievable for aerospace CNC machining?
Aerospace CNC machining typically targets tolerances of ±0.01mm to ±0.025mm for standard features. Critical features such as bearing bores, sealing surfaces, and mating interfaces may require ±0.005mm or tighter. Wire EDM can achieve ±0.002mm for ultra-precision cutouts and profiles. All critical dimensions should be inspected on a CMM with documented results provided in a First Article Inspection (FAI) report.
Do your suppliers hold AS9100 certification?
Rapid Manufacturing works with AS9100-aware suppliers in our network. For certified AS9100 Rev D requirements, we match your project with the appropriate supplier and can provide documentation on request. If your project has specific quality system requirements, include them in your quote request and we will match you with qualified suppliers accordingly.
What documentation do aerospace projects typically require?
Aerospace projects commonly require: material certifications (mill certificates with heat/lot traceability), First Article Inspection (FAI) reports per AS9102, CMM inspection reports, Certificate of Conformance (CoC), and process certifications for any special processes (anodising, plating, heat treatment). Specify your documentation requirements in your quote request and our team will confirm what can be provided.
Can you machine Inconel and other nickel superalloys?
Yes. Our supplier network includes manufacturers with experience in difficult-to-machine materials including Inconel 625 and 718, Hastelloy C-276, Waspaloy, and Rene alloys. These materials require specialist tooling, lower cutting speeds, and high-pressure coolant. Not all suppliers can machine nickel superalloys to aerospace tolerances — specify your material when requesting a quote so we can match you with the right facility.
