Constantan 6J40 chemical composition manufacturer Constantan 6J40 price

Manganese copper is a resistance alloy with copper and manganese as the main component. It has the same resistivity as constantan and basically similar resistance temperature coefficient. Compared with constantan resistance alloy, manganese copper has the advantage of low price because it does not contain higher-priced nickel, but its anti-oxidation performance is worse than constantan, and it can replace constantan wire resistance alloy in many aspects.
