More on nickel, cobalt and titanium alloys: superalloy machining. Don't see your alloy? Ask. If we haven't cut it before, we'll tell you.
Machining superalloys and titanium well
Nickel superalloys work-harden, hold heat at the cutting edge and wear tools quickly. Titanium conducts heat poorly and tends to chatter in thin sections. Both punish guesswork. We plan constant tool engagement, use high-pressure coolant and sharp carbide, and replace tools on a set schedule rather than waiting for them to fail. That keeps blade surfaces and dimensions consistent from the first part to the last.
Heat-lot traceability, every lot
- Mill test reports on file for every material lot
- Heat number tracked from receiving through each job to shipment
- Customer-supplied material logged and kept separate
- Material certs available with the certificate of conformance
Frequently asked questions
Do you machine Inconel?
Yes. Inconel 718 and 625 are regular materials in our shop, especially for turbine components, high-temperature flanges and oil and gas fittings. We cut them with sharp carbide, high-pressure coolant and conservative surface speeds, and set tool-life limits from experience.
Do you machine titanium?
Yes, Grade 2 (commercially pure) and Grade 5 (Ti-6Al-4V). Titanium flanges are one of our core product lines, and Ti-6Al-4V is a common blisk, impeller and blade material.
Do you machine Hastelloy and Waspaloy?
Yes. We machine every common Hastelloy grade (B-2, B-3, C-4, C-22, C-276, C-2000, G-30, N, S, W and X) and Waspaloy, along with Udimet, Haynes, Nimonic, René, Incoloy, cast alloys such as MAR-M 247 and CMSX-4, A-286, and cobalt alloys including Stellite and MP35N. Our superalloy machining page lists more than 100 grades.
Can you source material, or do we supply it?
Either. We buy from established mills and distributors with mill test reports (MTRs), or we machine customer-supplied material. Every lot is tracked by heat number from receiving to shipment.
Have a print or a STEP model?
Send it over. We review every RFQ by hand and include a lead time with every quote.
