Kovar/UNS K94610

Tlhaloso e Khutšoanyane:

Kovar (UNS K94610), motsoako oa nickel-iron-cobalt o nang le hoo e ka bang 29% nickel le 17% cobalt. Litšobotsi tsa eona tsa katoloso ea mocheso li tšoana le tsa likhalase tsa borosilicate le lirafshoa tsa mofuta oa alumina. E entsoe ka mokhoa o haufi oa lik'hemik'hale, e fana ka thepa e ka phetoang e etsang hore e tšoanelehe haholo bakeng sa litiiso tsa khalase ho isa ho tšepe ts'ebetsong ea tlhahiso ea bongata, kapa moo ho ts'epahala ho leng bohlokoa haholo. Thepa ea khoheli ea Kovar e laoloa haholo ke sebopeho sa eona le kalafo ea mocheso e sebelisoang.
