Alloy 188 Cobalt Alloy - Ams 5772

Cobalt Alloy 188 falls under the category of superalloys - an elite family of metallic composites purpose-engineered to endure extraordinarily hostile operating environments and withstand severe mechanical stresses.  Standard alloys would rapidly deteriorate under such punishing conditions, yet this superalloy exhibits remarkable resilience in the face of extraordinarily hostile environments that would compromise ordinary materials. Cobalt Alloy 188 exhibits exceptional resilience where standard materials would simply fail.

The presence of chromium, a key component at roughly 22%, allows a tenacious oxide layer to form on the alloy's surface, this acts as a barrier, which prevents corrosion. Cobalt itself is highly resistant to chloride-induced corrosion, a type of degradation that plagues many other alloys.

Industries that rely on Cobalt Alloy 188 include aviation, where it sees use in aircraft engines and hot section components and in the gas industry where it used in turbine engines.
