Cupronickel CuNi44 Ejò-nickel alloy resistance wire pẹlu alabọde-kekere resistivity
Alloy resistance bàbà-nickel yii, ti a tun mọ si igbagbogbo, jẹ ijuwe nipasẹ resistance itanna giga kan pọ pẹlu olusọdipúpọ iwọn otutu to peye ti resistance. Alloy yii tun fihan agbara fifẹ giga ati resistance si ipata. O le ṣee lo ni awọn iwọn otutu ti o to 600 ° C ni afẹfẹ.
CuNi44 jẹ alloy-nickel Ejò (CuNi alloy) pẹlualabọde-kekere resistivityfun lilo ni awọn iwọn otutu to 400°C (750°F).
CuNi44 ni igbagbogbo lo fun awọn ohun elo bii awọn kebulu alapapo, fuses, shunts, resistors ati awọn oriṣiriṣi awọn oludari.
