Exotic alloys & engineering plastics — quoted to print.
Hastelloy, Monel, Waspaloy. PEEK, Ultem, PTFE. When the standard alloy chart doesn't cover the application, K+G sources, qualifies, and machines the right material. AS9100D + ITAR.
Specialty material, machined right.
Exotic alloys and engineering plastics each carry their own machining playbook — feeds, coolant, tooling, fixturing all differ. K+G has run enough of these to know the playbooks; we don't learn on your part.
Nickel-based super-alloys
Hastelloy (C-22, X), Waspaloy, Rene 41. Chemical processing, aerospace hot-section, nuclear. Strict feed/speed control + carbide or ceramic tooling.
Copper-nickel alloys
Monel 400, Monel K-500. Marine, chemical, downhole. Excellent corrosion resistance in seawater and acid environments.
Engineering plastics
PEEK, Ultem, Torlon, PTFE. Medical, aerospace, semiconductor. Climate-controlled machining environments where dimensional stability matters.
Specialty applications.
Exotic alloys and engineering plastics serve specific industries. Click through to the matching vertical.
Aerospace
Waspaloy, Rene 41, hot-section structural. PEEK for thermal isolation.
/ IndustryMedical device
PEEK implants, surgical instrument insulators, diagnostic enclosures.
/ IndustryDefense
Hastelloy chemical-handling parts, exotic-alloy mil-spec hardware.
/ CapabilityCNC milling
Most exotic-alloy work starts on a 5-axis VMC.

Exotic-alloy quotes need explicit material spec, heat-treat state, and cert requirements. PDF + STEP is ideal.
