Alloy e thehiloeng ho koporo e nang le khanyetso e tlase e sebelisoa haholo ho sekhechana sa motlakase o tlase, relay overload overload, le lihlahisoa tse ling tsa motlakase o tlase. Ke e 'ngoe ea lisebelisoa tsa bohlokoa tsa lihlahisoa tsa motlakase tse tlase. Lisebelisoa tse hlahisoang ke k'hamphani ea rona li na le litšobotsi tse ntle tsa ho hanyetsa le botsitso bo phahameng. Re ka fana ka mefuta eohle ea terata e chitja, thepa e bataletseng le ea lakane.

CuNi2 khanyetso e tlaseHeating alloy e sebelisoa haholo ho "low-voltage circuit breaker", "thermal overload relay" le lihlahisoa tse ling tsa motlakase o tlase.
