Tungsten Machining RFQs for Shops That Cut Dense Metals
Preview each RFQ before you take it. Talk to the buyer directly. No commission on orders.
What an RFQ preview looks like
Enough to judge grade, effort and blank size. The buyer's name, company and files are released only after you take the lead.

Who qualifies
We keep the list short so buyers get serious quotes and each shop gets requests it can win.
- Tungsten experienceYou have cut heavy alloy, pure tungsten or tungsten copper on paid jobs.
- Material accessYou can buy sintered blanks or bar, or you work with customer supplied material.
- Response timeYou reply to buyers within 48 hours.
- ConfidentialityYou sign an NDA when the buyer asks for one.
- Honest quotingYou decline grades or tolerances you cannot hold rather than quote and miss.

Questions shops ask
Is one RFQ sent to many shops?
No. Each RFQ goes to 3 shops at most, and only to shops that cut the grade and part size in the request.
How do the terms work?
We explain them one-to-one before the first request is sent. Use the form on this page or email us.
What if a lead is not what the preview described?
Tell us and we check it. If the buyer contact does not respond or the request differs clearly from the preview, we follow up with you directly.
We only cut heavy alloy, not pure tungsten. Can we register?
Yes. Tell us which grades you cut and which you decline. We only send previews for the grades and processes you list, so a heavy alloy shop does not get pure tungsten parts that need grinding or wire EDM.
