Aerospace Structural Bracket Machining — Titanium, Aluminum, Documentation
Aerospace structural brackets — engine mount hardware, airframe fittings, actuator housings — are precision-tolerance parts in titanium and high-strength aluminum. Documentation depth (AS9102 first-article, material traceability, ITAR handling) matters as much as machining precision. This guide covers what aerospace bracket machining actually requires.
Materials and typical applications
| Material | Applications |
|---|---|
| Titanium Grade 5 (Ti-6Al-4V) | Airframe brackets, engine mount hardware, high-strength fittings |
| Titanium Grade 23 (Ti-6Al-4V ELI) | Critical structural where fracture toughness matters |
| Aluminum 7075-T6 | Airframe structural components, general aerospace structural |
| Aluminum 6061-T6 | Standard structural, jigs, secondary hardware |
| 17-4 PH / 15-5 PH | Structural components requiring corrosion resistance |
| Inconel 718 | Engine hot-section brackets, high-temperature applications |
Machining scope and precision
Aerospace bracket machining typically involves complex geometries — pocketed structural sections, radiused fillets, multi-face mounting features, tapped holes to specific thread specs (usually MJ or UNJ). CMM verification of every critical dimension.
Tolerances: ±0.0005" routine; ±0.0002" on critical fits. Surface finish 63 μin Ra typical; better on sealing or mating surfaces.
AS9102 first-article inspection
Aerospace first-article inspection (AS9102) requires structured documentation of every dimension on the print, with measurement traceability. Form 1 (part identification), Form 2 (product accountability), Form 3 (characteristic accountability) — the full set for aerospace-graded parts.
Any capable aerospace machining shop produces AS9102 packages. Ask specifically at quote time.
ITAR handling
Defense-adjacent aerospace work requires ITAR-compliant handling: US-person-only access to controlled prints, physical document control, controlled shipping, NDA discipline. B&R Productions supports ITAR-controlled work under document control.
Non-ITAR aerospace work handled under standard NDA on request.
Frequently asked questions
Where can I get aerospace structural brackets CNC machined in Texas?
B&R Productions in New Waverly, TX machines aerospace structural brackets regularly. Direct number for RFQs and rig-down work: (936) 291-7827.
How long does aerospace structural brackets machining typically take?
Depends on quantity and material availability. Standard work: 1–3 weeks. Emergency turnaround: same-day to 3 days when material is on the shelf. Call to discuss your specific job.
Can B&R produce AS9102 first-article packages?
Yes — structured AS9102-format first-article documentation on aerospace work. Discuss specific format requirements at quote time (some customers use their own FAI template).
Do you handle ITAR-controlled aerospace prints?
Yes — US-person-only access, physical document control, NDA discipline. Prints stay in-shop.
What tolerance can you hold on titanium structural brackets?
±0.0005" routine on critical structural features; ±0.0002" on fits with the right fixture. Titanium's low modulus makes rigid fixturing essential.
What's typical lead time for aerospace bracket machining?
2–4 weeks for standard structural work in stocked-material aluminum or 17-4 PH. Longer for titanium if material isn't on shelf. Emergency AOG turnaround available for repeat customers.
