About Tungsten Machining
A matching service for one narrow niche: parts machined from pure tungsten, tungsten heavy alloy and tungsten copper.
What we are and what we are not
We are not a machine shop. We do not own machines, buy tungsten stock or hold any of the material risk on your part. We read RFQs, know which shops actually cut each tungsten grade at which size, and put buyers in front of up to 3 of them. The shop you choose quotes you directly, machines the part and ships it. We take no commission on that order.
Why tungsten needed its own matching service
Most CNC quoting platforms are built for aluminum and steel. Tungsten heavy alloy, pure tungsten and tungsten copper behave differently on the machine, cost far more per kilogram, and only a subset of shops want the work or have run it before. Sending a general RFQ to a general platform usually means slow replies or quotes from a shop that has never cut the grade. We built a narrower list instead.
How a shop gets on the list
Before a shop receives previews, we ask which tungsten grades it actually cuts (pure tungsten, W-Ni-Fe, W-Ni-Cu or tungsten copper), what size and quantity range it takes, and which processes it runs beyond milling and turning, such as grinding or wire EDM for pure tungsten and carbide. A shop that says it only cuts heavy alloy does not get previews for pure tungsten parts. We do not independently audit shop floors, and we say so plainly: you should still ask any shop for references, a material certificate and, where it matters, a first-article inspection before you place a production order.
How a match is made
We read the drawing or the quick RFQ form for grade, size, quantity, tolerance and deadline. Shops first see a short preview with none of your contact details or files. Files and contact details go only to the shops we match, 3 at most, so your drawing is not broadcast to an open bidding board. If you ask for an NDA, we hold everything until it is signed.
How this site is written
The guides on this site are written from public engineering references (ASTM standards, material producer datasheets and general machining references) and from what shops tell us about cutting each grade. Numbers on density, tolerance and hardness are always labeled "typical" because they vary by mill, lot and shop. We do not publish invented client counts, years in business or certifications. See the editorial policy for how each guide is sourced and reviewed.
