C&W Manufacturing machines Inconel 718 and 625, Hastelloy X and C-276, Haynes 282 and other nickel superalloys for aerospace, turbine and defense programs. These alloys work-harden under the tool, hold their strength at temperature, and conduct heat poorly, so they are machined with a plan: roughed in the soft condition, heat treated where the specification calls for it, and finish-machined so aged parts come out on size. Five CNC mills including 5-axis, four CNC lathes, an AS9100D quality system and AS9102 first-article inspection. ITAR registered.
The facts a sourcing engineer needs first. Everything below is repeated in more depth on our services and about pages and documented on the certifications page.
Inconel 718 roughly doubles its yield strength when aged, and tool life falls accordingly. Roughing in the annealed condition and finishing after age is the single largest cost lever; our Inconel machining guide walks through the sequence.
Nickel alloys conduct heat a fraction as well as steel, so the cutting zone runs hot and the alloy work-hardens if the tool dwells. Sharp edges, steady feed and generous coolant keep the cut predictable.
AMS 5663 is solution-treated and aged bar; AMS 5662 is annealed for the shop to age; AMS 5962 is direct-aged. Ordering the wrong one costs a heat-treat cycle. See Inconel AMS specifications.
718 for strength to about 1300°F, 625 for corrosion and weldability, Hastelloy X for oxidation to 2200°F, C-276 for aggressive wet corrosion, Haynes 282 for creep strength with weldability. Our guides to 625 vs 718 and Hastelloy and Haynes compare them.

Superalloy parts can cost 20 to 50 times the same part in aluminum, mostly in machining time. Generous radii, realistic tolerances and near-net stock all help; the DFM guide explains which changes matter most.
Inconel 718 and 625, Hastelloy X and C-276, and Haynes 282 are the alloys we run most, with Waspaloy and others quoted on request. We machine bar, plate and forgings to the AMS specifications called out on the drawing.
Three reasons: the material itself costs many times what aluminum does, the alloy work-hardens and runs hot at the cutting edge so speeds are a fraction of those for steel and tool wear is heavy, and precipitation-hardened grades need a heat-treat cycle planned into the machining sequence. Machining cost typically runs 5 to 20 times the aluminum equivalent.
Both, in a planned sequence. We rough in the annealed condition with stock left on, send the part for solution treatment and aging per AMS 2774 or the drawing, then finish-machine to size. Finishing after age accounts for the small dimensional change and avoids cutting the full-hard material any more than necessary.
Yes. C&W fabricates nickel alloys for aerospace and defense work. Precipitation-hardened grades are welded in the annealed condition and aged afterward so the weld ages with the base metal; tell us at quote time if welding is part of the job.
Yes. Turbine, exhaust and defense components in these alloys are often export-controlled. C&W is ITAR registered, JCP DD-2345 certified and holds CMMC Level 2 status; controlled data is accepted only over a U.S.-hosted secure channel.
Yes. AS9102 first article reports with CMM data, AMS material certifications traceable to heat, and heat-treat and hardness records come with aerospace lots under our AS9100D and ISO 9001:2015 quality system.
