Get matched with an Inconel shop How it works

CNC-machined metal manifold with bores on multiple faces — A nickel superalloy's crystal structure is what makes it strong at high temperature, and hard on tools and shops that are not set up for it.

Why buyers send Inconel work here

It comes down to the match: shops that fit your part, from the first quote.

Matched by specialisation

Your RFQ goes to up to 3 shops that run Inconel regularly, picked for your alloy grade, part size and tolerance. Not a general directory.

Professional suppliers

Shops in the network quote to your drawing, communicate clearly and keep you updated while your parts are made.

You deal with the shop

Quotes, terms and delivery are agreed between you and the shop. Free for buyers.

Does your part need a specialist Inconel shop?

Plenty of "we machine everything" shops will quote a nickel superalloy part and struggle with it. Tick what applies to yours. Two or more ticks means alloy experience matters more than a low bid.

Alloy is Inconel 625, 718, 825 or another nickel/cobalt superalloyNot stainless, not titanium. A true nickel superalloy calling for matched tooling and speeds.
Mill cert and PMI traceability requiredThe part goes into aerospace, energy or another application where a substitute alloy cannot slip through.
Tight tolerance on a work-hardening materialBores, threads or faces held under 0.02 mm on an alloy that hardens fast under the tool.
First article inspection or AS9100-style paperwork expectedThe buyer needs an FAI report, not just a part in a box.
Low volume or prototype runTooling and setup cost dominate the price, so shop experience with the alloy matters more than usual.

CNC spindle machining a round metal part

Where these parts end up

Turbine and combustor components
Exhaust and manifold parts
Downhole and wellhead hardware
Valve trim and bodies
Fasteners and brackets for hot sections
Heat exchanger and process parts
Furnace fixtures and baskets
Shaft seals and impellers

Inconel work-hardens as the tool passes over it, so a shop without the right speeds and tooling burns through carbide fast and still misses tolerance. That is the gap a specialist shop closes.

Inconel 625 or 718?

Both are nickel-based superalloys, but they are chosen for different reasons and machine differently. Knowing which one your application needs changes the RFQ and the shop that fits it.

Inconel 625

Solid-solution strengthened, not age-hardenable. Chosen mainly for corrosion resistance.

Marine, exhaust and chemical processing environments
Easier to weld than 718
Slightly more forgiving to machine, still work-hardens fast

Inconel 718

Age-hardenable, so it can be machined softer and heat treated after for high strength.

Aerospace, gas turbines and fasteners
The most requested grade in our network
Harder on tools once aged, so sequence matters

Alloys and typical tolerances

What to expect when a shop quotes each grade. These are typical ranges, not promises. The shop that quotes you confirms what it can hold on your geometry.

Alloy	Common use	Typical tolerance
Inconel 625	Marine, exhaust, chemical processing. Excellent corrosion resistance, weldable, high temperature.	±0.02 to ±0.05 mm is common
Inconel 718	Aerospace, gas turbines, fasteners. Age-hardenable. The most requested grade in our network.	±0.02 to ±0.05 mm is common
Inconel 825	Oil and gas, downhole tools. Stress corrosion cracking resistance in sour service.	±0.02 to ±0.05 mm is common
Inconel 600 / 601	Furnace components, heat treatment fixtures. Available on request via specialized shops.	±0.05 mm is a safer target

Industries we match Inconel work for

Different industries bring different paperwork. Mention material certs, first article inspection or cleanliness rules in your RFQ so we match shops that already work that way.

Aerospace

Engine fasteners, brackets, turbine housings, exhaust components.

Oil and gas

Downhole tools, valve trim, wellhead components, sour service parts.

Power and turbine

Combustion liners, shaft seals, heat exchanger parts, generator hardware.

Chemical processing

Pump impellers, reactor internals, process valve bodies, flanges.

Parts, grades and callouts by application

How it works

One RFQ from you. A short list of shops that fit. No bidding platform and no middleman on the order.

Send your RFQ
Upload a drawing and tell us alloy, quantity, tolerance and when you need it. Takes about three minutes.
We match up to 3 shops
We read the drawing and pick shops with real Inconel or superalloy experience. You hear from us within 24 business hours.
Shops quote you directly
Each shop contacts you with a quote. You compare, ask questions and place the order with the one you choose.

What drives the price of an Inconel part

Five things decide most quotes. If a price looks high, one of these is usually the reason.

Why Inconel 718 parts cost so much to machine

How shops turn, mill, EDM and grind Inconel

Tooling and cutting speedInconel work-hardens fast. Ceramic or coated carbide tooling matched to the alloy keeps cycle times and tool wear in check; the wrong tooling doubles both.
Material cert and PMINickel alloy stock costs far more than mild steel per kilo. Mill cert verification and PMI testing on incoming material add a line to the quote, and catch substitute alloys before they matter.
Tolerance and inspectionEvery tolerance tighter than the part needs adds machine time and inspection, especially on a work-hardening material. FAI reports add a fixed fee.
QuantitySetup spreads over more parts as quantity rises. On 1 to 10 pieces, tooling and programming dominate the price.
FinishingPassivation, heat treatment and specialty coatings add cost and a few days of lead time.

Questions buyers ask

Something else? Email .

Is this service free for buyers?

Yes. You pay nothing to send an RFQ or to receive quotes. Price, terms and delivery are agreed between you and the shop.

Do you machine Inconel parts yourselves?

No. We are a matching service. The shops that quote you run the machines and hold the material certs. You place the order with them directly.

Who sees my drawing?

Shops first see a short preview with part type, alloy, quantity and tolerance. It does not include your name, company or files. Your contact details and files go only to the shops we match, up to 3. If you ask for an NDA, we hold the files until it is signed.

Which Inconel grades can shops in your network quote?

Inconel 625, 718 and 825 most often, plus 600 and 601 on request. Tell us the grade and spec (AMS, mill cert, PMI) on the RFQ so we match shops that already run that alloy.

What's the typical lead time?

Prototype: 3 to 5 weeks, including raw material lead time, since nickel alloy stock is not always on shelf. Production batches of 50 to 500 pieces: 6 to 10 weeks. The shop that quotes you confirms the real number for your part.

Can a shop sign an NDA before reviewing my drawing?

Yes. Tick the NDA box on the RFQ form and we hold your files until an NDA is signed between you and the matched shop.
