Titanium
Grade 5 (Ti-6Al-4V), Grade 2, Grade 23 ELI, Grade 9
The default when the drawing says titanium is Grade 5 annealed. Grade 23 with ASTM F136 traceability for medical prototypes.
Trading company. Titanium and hard alloys. Production managed.
Exotic alloy machining, managed from drawing to delivery
We are an export trading company specialised in titanium and other hard-to-machine alloys. Send a drawing and an engineer sends you a priced quote within 24 business hours. We buy the machining from an audited shop in the network we manage, follow the order on the floor, send you a progress update every week, inspect before packing and ship on our own paperwork. NDA by default.
Prefer email? Send the drawing to
- One PO, one invoice
- You buy the finished part from us. One contact, one purchase order, one invoice, and the responsibility for quality and schedule sits with us.
- An engineer on every order
- An engineer is assigned to your order from drawing review to packing and is the person who answers your questions.
- Weekly progress update
- A written update every week while your parts run, with what was done, what is next and anything that moved.
- Inspection before packing
- Parts are measured against your drawing before they are packed and an inspection report ships with every order.
What we are
A trading company that manages the shops it buys from
Both halves matter. The first says who you are buying from. The second is what you are paying for.
Trading company
- We buy the machining and sell you the finished part, on our own quote, order acknowledgement and invoice.
- The shop that cuts your part is paid by us and never deals with you. You deal with one company for quoting, questions, claims and paperwork.
- Our revenue is the margin between what we pay the shop and what you pay us. It is not a commission and there is no separate fee.
- An NDA is offered by default, before a drawing is shared with anyone. One contact holds your files, not a list of shops.
Production management
- A managed network of professional CNC shops that we run, audited on the floor before an order in titanium, Inconel or hardened steel is placed with them.
- An engineer follows every order: drawing review before placement, material check, first article, in-process checks and final inspection.
- A weekly progress update in writing while the order runs, so you never have to ask where your parts are.
- Inspection before packing, against your drawing, with the report attached. A part out of tolerance does not leave.
How the order runs
Five milestones, and one engineer through all of them
No account to open with a machine shop, no negotiating in a second language, no chasing a factory across a time zone.
-
Drawing
You send a STEP or PDF with the alloy, condition, quantity, finish and the tolerances that matter. An NDA first if you want one.
-
Quote
An engineer reads the drawing, flags what will cost money and sends a priced quote with a lead time within 24 business hours.
-
Make
You issue one PO to us. We place the work with an audited shop in our network, agree the schedule and check the material certificate before the first cut.
-
Inspect
First article, in-process checks and a final inspection against your drawing before anything is packed. You get a weekly update throughout.
-
Ship
Parts leave with the inspection report, the mill certificate where requested and our commercial paperwork. If a part is wrong, it is ours to fix.
Capabilities
Alloys, processes and the tolerances we plan around
The numbers below are typical for hard alloys on the right machine with the right tooling. They are planning figures, and the numbers that apply to your part are confirmed on your quote.
| Process | What it suits | Typical tolerance | Send this with it |
|---|---|---|---|
| CNC milling, 3-axis | Prismatic parts, brackets, plates, pockets and bosses | ±0.05 mm typical, ±0.02 mm on called-out features | STEP plus a PDF with datums and critical dimensions |
| CNC milling, 4 and 5-axis | Multi-face parts, compound angles, thin-wall housings, impeller-type geometry | ±0.05 mm typical, ±0.02 mm on called-out features | STEP, PDF, and tell us which faces mate |
| CNC turning and mill-turn | Shafts, pins, bushings, threaded fittings, fasteners | ±0.02 mm typical on diameters, tighter with confirmation | PDF with thread call-outs and surface finish |
| Hard turning and grinding | Hardened steel 45 to 62 HRC, bearing seats, tool steel dies, ground faces after heat treatment | ±0.01 mm typical, Ra 0.4 µm ground | Hardness, condition and grind stock on the drawing |
| Wire and sinker EDM | Sharp internal corners, thin slots, hardened profiles carbide will not survive | ±0.01 mm typical on profile | DXF or STEP with the profile and plate thickness |
| Heat treatment and finishing | Stress relief, ageing of 17-4 PH and 718, anodising, passivation, bead blast | Per specification on the drawing | The spec number, or the purpose if you do not have one |
Alloys we supply
Nickel superalloys
Inconel 625, Inconel 718, Hastelloy C-276, Monel 400
Work-harden in front of the tool. Condition on the drawing changes the job, not just the hardness number.
Hardened and tool steel
17-4 PH, 4140, H13, D2, A2, M2, 52100
Machine-then-harden with grind stock, or buy hard and finish with CBN. The route is decided at drawing review.
Stainless and duplex
316L, 321, 410, 2205 duplex, 2507 super duplex
Gummy, heat-retaining. Chip control decides the finish more than the cutter does.
Low-expansion and refractory
Invar 36, Kovar, molybdenum, tungsten alloy
Quoted on material availability. Process proving matters more than cycle time.
Why hard alloys go wrong
Four things that turn a quote into a late, expensive order
These alloys are not hard to cut. They are unforgiving of a shop that cuts them occasionally. These are the four points the engineer checks before your order is placed.
- Work hardening
- Titanium and nickel alloys harden under a dull tool or a light rubbing cut. A shop that is new to them leaves a glazed surface the next tool cannot get under. We place these orders only with shops that cut the alloy every week, and the engineer checks the tooling plan before the job starts.
- Heat and tool wear
- Titanium and Inconel conduct heat badly, so the heat stays at the cutting edge. Feeds, coolant pressure and insert changes decide whether a part holds size from the first piece to the last. The weekly update tells you when inserts were changed, not just that the job is running.
- Thin walls and distortion
- Residual stress in bar and plate shows up as a wall that moves after the last pass, and a hardened part moves again after heat treatment. We ask for a stress-relief step and a roughing-then-finishing sequence where the geometry needs it, and we quote it that way instead of discovering it at inspection.
- Threads, galling and hardness
- Titanium threads gall against titanium. A thread in a part that will be hardened has to be cut before heat treatment or ground after it. Thread form, class of fit and whether an insert belongs in the hole are decided at drawing review, before anyone taps a hole that then has to be re-made.
Industries
Who buys hard-alloy parts this way
Prototypes, small lots and parts with several process steps, from buyers who want one contact and an NDA before a drawing moves.
- Medical device prototypes
- Grade 23 and Grade 5 instrument and implant prototypes for development, with certificate traceability. Not production implants.
- Motorsport
- Suspension components, fasteners, brackets and heat-shield hardware in titanium and Inconel, from one-offs to small batches.
- Aerospace R&D
- Test fixtures, brackets and development hardware. Export-control screening is part of the quote. Not flight-certified production.
- Defence-adjacent and dual-use
- Development parts for buyers who need one contact and an NDA before a drawing moves. Subject to export-control screening.
- Oil, gas, marine and subsea
- Inconel 625, Monel, duplex and Grade 2 fittings, housings and sensor bodies where corrosion sets the material, not strength.
- Energy, process and tooling
- Hastelloy and 625 process parts, 718 fixtures for high temperature, H13 and D2 die components in hardened condition.
Quick quote
Start with what you have
An alloy, a quantity, a description and a file. If the drawing is not final, describe the part and the engineer will tell you whether it is worth quoting here at all.
The full form adds tolerance, finish, certificates and delivery date. The NDA box is ticked by default on both.

Why shopping a titanium drawing to many shops can backfire
Sending one titanium drawing to many shops for competing quotes feels efficient. Here is what it costs in confidentiality, pricing behaviour and your own time.
For CNC shops that cut hard alloys
We bring the order, you machine to print
A shop in our network receives a purchase order from us, in Vietnamese terms, with a drawing that has already been through our engineering review and a material certificate that has already been checked. Our engineer is on your floor for the first article. The buyer, the export paperwork and any claim are ours.
Suppliers of titanium and nickel alloy stock, cutting tools, coolant, heat treatment and surface processing register on the same page. Nothing is sold here: we keep you on file and buy where the product and the price are right.
- Hard alloys, weekly

Questions
What buyers ask us first
Are you a trading company or a factory?
A trading company, and we say so. We do not own machines. We buy machining in titanium, Inconel and hardened steel from audited shops in a network we manage and sell you the finished part on our own quote, order acknowledgement and invoice. What makes that worth paying for is the production management: an engineer on every order, a weekly progress update and inspection before packing.
How are you paid?
From the margin between what we pay the shop and the price on your quote. It is a margin, not a commission, and there is no service fee and no charge for quoting. You see one price per part and one invoice.
Who do I contract with, and who is responsible if a part is wrong?
You contract with us. The purchase order, the invoice and the claim are all with CNC Titan. If a part does not meet the drawing it is reworked or re-made at our cost, and sorting that out with the shop is our job, not yours.
Do you sign an NDA before I send a drawing?
Yes, and we offer it by default. Tick the box on the quote form or ask by email and we hold any files until the NDA is signed. Drawings are shared only with the one shop that machines the part, under its own confidentiality terms with us.
Which alloys do you supply?
Titanium Grade 5, Grade 2 and Grade 23 ELI. Inconel 625 and 718, Hastelloy C-276 and Monel 400. 17-4 PH, 4140 and the tool steels H13, D2, A2 and M2 in hardened condition. 2205 and 2507 duplex. Invar, Kovar and refractory metals on material availability. If your alloy is not on the list, send it anyway and we say plainly whether we can take it.
What is a typical lead time?
It depends more on material availability than on machining. Grade 5 bar in common sizes is usually quick; Inconel plate, ELI titanium and tool steel in unusual sections can take weeks from the mill. Your quote states a lead time in working days from the starting point it names, with the material lead time stated separately, and the weekly update tells you where the order is against it.
What ships with the parts?
An inspection report against your drawing on every order, the mill certificate when requested, the processor certificate for any specified heat treatment or finish, and our commercial paperwork. The standard inspection level is confirmed on your quote.
Where are the parts made and can I visit?
In Vietnam, in shops we audit and manage. We are based in Ho Chi Minh City. A visit to the shop running your order can be arranged through us for a production order; we do not publish the shops and we do not hand out their contact details.
Do you handle export-controlled parts?
We screen every aerospace and defence-adjacent request. If a part is controlled under ITAR, EAR or an equivalent regime in a way that we cannot lawfully receive, we decline it and say why. If you are not sure, tell us the end use and we will say what we can take.
Is there a minimum order?
Prototypes and small lots are the point of this service, so there is no minimum quantity. Whether a minimum order value applies is stated on your quote and in our terms of sale.
