Nickel Chromium Alloy 40 Resistance Ribbon Ni40cr20 Electric Heater Waya
Nickel Chromium Resistance Alloy Resistohm 40 Resistance Ribbon Ni40cr20 onigbona ina
Ni40Cr20jẹ austenitic nickel-chromium alloy (NiCr alloy) fun lilo ni awọn iwọn otutu to 1100°C (2010°F). Awọn alloy ti wa ni characterized nipasẹ ga resistivity ati ti o dara ifoyina resistance. O ni o ni ti o dara ductility lẹhin lilo ati ki o tayọ weldability.
Awọn ohun elo aṣoju funNi40Cr20jẹ awọn igbona ibi ipamọ alẹ, awọn ẹrọ igbona convection, awọn rheostat ti o wuwo ati awọn igbona afẹfẹ. A tun lo alloy naa fun awọn kebulu alapapo ati awọn igbona okun ni sisọ ati awọn eroja de-icing, awọn ibora ina ati awọn paadi, awọn ijoko ọkọ ayọkẹlẹ, awọn ẹrọ igbona ipilẹ ati awọn igbona ilẹ, awọn resistors.
