Alloy800 6J22 6J23 NiCr20AlSi 0.1mm Niobium Alloy Wire Enamel Coating 300 Working Temp Resistivity 1.33 .m Density 8.1
OHMALLOY 133 (NiCr20AlSi, Alloy800, 6J22, Karma, 6J23,Evanohm) is mainly made of nickel, chromium, aluminum and iron. It has a wider working temperature range from -60°C~300°C.The resistivity is 2~3 times higher than manganin. It has lower temperature coefficient of resistance(TCR), lower thermal EMF versus copper, good permanence of resistance for a long period of time and strong anti-oxidation. Its working temperature range is wider than manganin(-60~300℃). It is suitable for making fine precision resistance elements and strain.
