Refractory-metal shops: the RFQs nobody else will quote
Molybdenum, TZM, tungsten, and tantalum RFQs come to us because the big marketplaces will not route them. If your shop has the ventilation, PPE protocol, and sourcing relationships, we have the work.
RFQs on the board
The refractory work we have on the board right now
A short list of RFQ categories we have received in the last several weeks. If this is the kind of job your shop runs, you are exactly who we need to add.
Molybdenum (99.95%) machining and EDM
- Glass-melt electrodes, furnace hardware, sputter-target backing plates
- Heat sinks and thermal spreaders for semi and defense R&D
- Sinker EDM features and wire EDM profile cuts in moly plate and rod
TZM (Ti-Zr-Mo) parts for high-temperature service
- Hot-zone components for vacuum furnaces and crystal growth
- Thin-wall tube and rod for aerospace and research reactors
- Qty 1–50 with full material certs and lot traceability
Tungsten and tungsten-copper (W-Cu)
- EDM electrodes, resistance-weld tips, counterweights
- Radiation shielding geometry and shaped collimators
- Finish-ground features to ±0.0005 in on W-Cu composites
Tantalum, niobium, and rhenium
- Chemical-process components (crucibles, baffles, heat exchangers)
- Capacitor-grade tantalum work for electronics and medical implants
- Niobium superconductor and accelerator parts
If any one of these is a routine job in your shop, tell us on your profile and we start sending the matching RFQs.
What qualifies you
What a qualified refractory shop looks like
Refractory metals are not a reach for a general CNC shop — they require specific sourcing, equipment, and safety protocols. We only route this work to shops that have them.
- Material sourcing relationships
- Direct accounts with Plansee, H.C. Starck, Elmet, Edgetech Industries, or equivalent mills for 99.95% moly, TZM, pure tungsten, and W-Cu grades.
- Carbide tooling and rigid setups
- Moly and tungsten are gummy or brittle depending on form; the shop needs the tooling library and SFM experience to run them without scrap.
- EDM in-house or trusted partner
- Wire EDM, sinker, or small-hole EDM for features milling and grinding cannot reach. Moly EDM is routine in semiconductor and glass-industry supply chains.
- Ventilation and dust capture
- MoO₃ fumes during EDM and moly dust during grinding are documented health hazards. HEPA-rated collection and dedicated wet-process stations expected.
- PPE and training protocol
- Written SDS program for refractory metals, respiratory PPE, and separation of refractory work from standard shop traffic.
- Material traceability
- Mill certs, lot numbers tied to the job, and dedicated storage so refractory stock is not mixed with the aluminum bar.
- Industry experience (helps)
- Semiconductor equipment, vacuum furnace, crystal growth, glass industry, defense R&D, or accelerator / fusion research backgrounds.
What you get
What a refractory partner gets
Jobs priced like specialty work
We do not pressure refractory-metal quotes into prototype-aluminum lead times or budgets. Customers coming to us for moly know it is a specialty quote.
Free to join; no fees
No subscription, no per-RFQ fee, no commission on your quote. We get paid by the customer, separate from your price.
Realistic lead times
We quote 3–6 week lead times to buyers up front on refractory jobs so you are not held to a prototyping schedule you cannot hit.
Material-cost transparency
You quote material separately; mill lead times and lot minimums are communicated to the customer so they understand why.
Keep your own customers
We do not approach your existing accounts. The buyers we route are new to your shop.
Direct line to our sourcing team
If a customer asks for something you have run before but not exactly, we can introduce you directly rather than guessing at the RFQ.
