Core Composition & Superior Electrical Properties of Evanohm 6J22

Also known as Karma alloy, Evanohm 6J22 is a nickel-chromium-aluminum-iron precision resistance alloy with balanced copper, nickel, aluminum and iron elemental ratios. Compared with widely used Manganin resistance alloy, 6J22 boasts multiple decisive technical strengths:

Its resistivity reaches 2–3 times higher than Manganin, enabling thinner wire designs for compact micro-resistance elements;
Ultra-low temperature coefficient of resistance (TCR) and minimal thermal EMF vs copper, eliminating measurement deviation in precision circuits;
Excellent long-term resistance stability, with nearly zero resistance drift under continuous service;
Outstanding high-temperature oxidation resistance, supporting a much wider working temperature range of -60°C to 300°C, far exceeding Manganin’s temperature limit.

Thanks to these stable electrical features, Evanohm 6J22 wire is the primary raw material for fine precision resistors, strain foil, strain gauges and high-precision sensor components used in aerospace, industrial measurement and new energy equipment.

As a reliable China nickel alloy supplier, ZYTC Alloy strictly controls element ratios and trace impurity content of all in-stock 6J22 wire, guaranteeing consistent resistivity and TCR performance across every production batch to meet high-precision electronic manufacturing demands.
