European Vacuum Brazing Supplier Shortlist
Nickel-based superalloy components · Aerospace application · Public-source verification
Executive result
Five suppliers merit RFQ consideration. Three are strong public-source matches; two show compelling technical fit but retain one material- or accreditation-scope item to verify before use in a live sourcing process.
| Supplier / site | Confidence | Evidence-backed fit | Status |
|---|---|---|---|
| FGP Lufton Yeovil, UK | HIGH | Vacuum brazing; Inconel/Nimonic; aerospace; NADCAP metal joining / heat treatment | RFQ |
| Aalberts Surface Technologies Eindhoven, NL | HIGH | Vacuum brazing; nickel alloys; aerospace; NADCAP + AS/EN9100 | RFQ |
| Wall Colmonoy Aerobraze Pontardawe, UK | HIGH | Vacuum brazing; aerospace; NADCAP brazing; nickel-based brazing expertise | RFQ |
| Barnes Aerospace Technologies Poland | MED-HIGH | Aero-engine vacuum brazing; NADCAP AC7102; OEM approvals | VERIFY MATERIAL |
| TAG Dolzago, IT | MED-HIGH | Vacuum brazing of nickel / cobalt superalloys for aeronautical use | VERIFY NADCAP SCOPE |
What this shortlist establishes
Included
Publicly evidenced process capability, material and aerospace fit where available, accreditation claims / scopes, source traceability, and a confidence assessment.
Not assumed
Current capacity, lead time, pricing, part-specific process qualification, customer-source approval, or engineering suitability for the buyer’s drawing.
Evidence matrix
| Supplier | Vacuum brazing | Ni-based material | Aerospace | NADCAP / quality | Assessment |
|---|---|---|---|---|---|
| FGP Lufton | ✓ | ✓ | ✓ | ✓ | Strong combined fit; material and special-process evidence align. |
| Aalberts Eindhoven | ✓ | ✓ | ✓ | ✓ | Strong combined fit across capability, material, aerospace and quality evidence. |
| Wall Colmonoy | ✓ | ✓* | ✓ | ✓ | Strong process / sector fit; confirm exact base-alloy / filler / cycle combination. |
| Barnes Aerospace Technologies | ✓ | ? | ✓ | ✓ | Very strong aerospace / accreditation evidence; public material evidence is not explicit enough. |
| TAG | ✓ | ✓ | ✓ | ? | Excellent technical/material fit; current exact brazing accreditation scope should be confirmed. |
* Nickel-based brazing expertise and supernickel-alloy aerospace work are publicly evidenced; part-specific process compatibility still requires buyer confirmation.
Supplier notes & primary evidence
FGP Lufton RFQ
FGP states that its Lufton facility has NADCAP approvals for metal joining and heat treatment, with vacuum brazing among listed special processes. Its published material list explicitly includes Inconel and Nimonic.
Aalberts Surface Technologies RFQ
The Eindhoven operation publishes high-temperature / vacuum brazing capability and identifies nickel alloys in aerospace applications. It states AS/EN9100 and NADCAP certification.
Wall Colmonoy Aerobraze RFQ
The UK Brazing Centre states AS9100 approval and NADCAP approval for Heat Treatment / Brazing, with Rolls-Royce customer approvals and extensive nickel-based brazing expertise.
Barnes Aerospace Technologies VERIFY MATERIAL
Barnes describes its Polish sites as high-performance treatment/coating providers for aero-engine components and lists NADCAP Heat Treating AC7102 including vacuum brazing. Public evidence does not explicitly tie nickel-superalloy base material to vacuum brazing at those sites.
TAG VERIFY SCOPE
TAG explicitly publishes vacuum brazing on nickel- and cobalt-based superalloys for aeronautical applications. The exact current NADCAP scope covering brazing was not established from the public evidence reviewed.
Recommended RFQ verification
Confirm current Nadcap/eAuditNet scope for the exact site and brazing process, plus customer-specific approved-source requirements.
Send drawing, alloy/condition, filler specification, joint design, cleanliness requirements and applicable customer / AMS specifications.
Confirm furnace working zone, vacuum capability, pyrometry class, batch controls and required pre-braze cleaning.
Request capacity, lead time, MOQ / batch economics, qualification cost and export-control constraints.
Method
This sample is supplier-discovery intelligence, not engineering approval, compliance certification, or a substitute for the buyer’s approved-source / supplier-quality process.
