Cobalt has also been used as a treatment for anemia, because it stimulates red blood cell production. (1) 1. Chronic exposure to cobalt by inhalation in humans results in effects on the respiratory system, such as respiratory irritation, wheezing, asthma, decreased lung function, pneumonia, and fibrosis.

Alloy 718 is a precipitation hardenable nickelbased alloy designed to display exceptionally high yield, tensile and creeprupture properties at temperatures up to 1300°F. The sluggish agehardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling.

Metallosis is a type of metal poisoning that can occur as a side effect of joint replacement devices with metal components, such as metalonmetal hip replacements or other metal implants. These devices are made from a blend of several metals, including chromium, cobalt, nickel, titanium and molybdenum.

Cobalt and Cobalt Alloys. Particular emphasis is placed on cobaltbase alloys for wear resistance, because this is the single largest application area of cobaltbase alloys. In heatresistant applications, cobalt is more widely used as an alloying element in nickelbase alloys with cobalt tonnages in excess of those used in cobaltbase heatresistant alloys.
