COSTANTANA o Alloy 401
Описание
Electrical resistivity (Ω·m) 4.9×10-7[1]
Costantan is a binary alloy, containing copper (60%) and nickel (40%) which a resistivity of approximately 4.9 x 10-7 Ω·m.
Its name is connected to its property of more or less maintaining its own resistivity unchanged as temperature changes.
