Machinability
Excellent machinability by cold, hot pressure, satisfactory welding, turning, milling, grinding, drilling. During processing niobium metal dust irritates eyes, skin, is flammable. Its individual compounds are very toxic. Maximum permissible concentration of Nb is 0.01 mg/l. If ingested, niobium is able to cause severe neuritis with further limb paralysis.
Application
Rocket, aircraft, space technology, radio, electronics, industrial chemistry and nuclear energy. Manufacture of electrolytic condensers, manufacture of pipe fittings for heat-exchange circuits of nuclear boilers.
Analogues
GOST: Нб5В2МЦ, 5В2МЦ-1,5В2МЦ-2.
