Product Description

Manufacturer nicr alloy Karma / Evanohm strip /foil 0.09mm 0.08mm 0.05mm price

Karma is a precision alloy material made of iron nickel aluminum alloy, Its chemical composition is mainly 70.6% metallic elements and 0.04% carbon, with a single-phase austenitic structure, a density of 8.3g/cm ³, a tensile strength of ≥ 690MPa, and an elongation of ≥ 18%. This alloy has a resistivity about three times that of manganese copper, a low temperature coefficient of resistance, and a small thermoelectric potential for copper. It has good long-term stability and oxidation resistance, and is suitable for various temperature environments. Mainly used for manufacturing precision resistance components, strain gauges and other measuring instrument components.

Karma alloy is mainly used to manufacture precision resistance components for various measuring instruments and meters, such as high-precision resistors, strain gauges, and micro resistance components. Due to its excellent physical properties, this material has wide applicability in the field of industrial instrument manufacturing.

Supply form: Wire, strip, foil
