1Cr13Al4 FeCrAl alloy Light Flat Strip/Irinna jakejado fun Lilo Resistors

Fecral Alloys ati Nickel-chromium alloys ni a ti yan lati jẹ ohun elo resistive fun resistor ifibọ nitori nickel-chromium alloys ni agbara eletiriki giga ti o jẹ lilo pupọ fun awọn resistors fiimu tinrin [1, 2]. Iduro dì ti fiimu alloy nickel-chrome ti o ni 20% chromium le jẹ giga bi 2-3 kilo ohms ati tun ṣetọju iduroṣinṣin to dara. Olusọdipalẹ otutu 1 ti resistance (TCR) fun olopobobo nickel-chrome alloy jẹ nipa 110 ppm/°C. Nipa sisọ iwọn kekere ti ohun alumọni ati aluminiomu pẹlu nickel-chromium, iduroṣinṣin iwọn otutu ti ni ilọsiwaju siwaju sii.
