Product Desciption

Karma(Ni-Cr-Al-Fe)

Products Description
Karma alloy have common name Nikrothal L/Evanohm/Alloy 800.Karma alloy is mainly composed of nickel, chromium, aluminum and iron.The resistivity is about three times higher than that of manganese copper, and has a lower resistance temperature coefficient and a low thermoelectric potential to copper, good resistance long-term stability and oxidation resistance performance.The temperature is wider than that of manganese copper.Suitable for making precise micro resistance element and strain gauge.
