EVANOHM R - DIN NiCr20AlSi(2.4872) Description:

Standard : "DIN NiCr20AlSi, 2.4872 Other Names: ISAOHM"

EVANOHM R is a nickel-chromium-aluminum-silicon (NiCrAlSi) high-resistance alloy designed for precision electrical resistance applications requiring excellent resistance stability over a wide temperature range.

Compared with conventional nickel-chromium resistance alloys such as NCH-1 (NiCr8020), EVANOHM R offers a significantly lower Temperature Coefficient of Resistance (TCR), enabling more stable electrical performance and improved accuracy in precision resistor applications.

The alloy combines high electrical resistivity, excellent oxidation resistance, heat resistance, corrosion resistance, and long-term stability, making it suitable for demanding electronic and electrical components.

Typical applications include precision resistors, shunt resistors, temperature sensors, current-sensing elements, fuses, measuring instruments, and other electronic components requiring highly stable resistance values.

Exceptional Electrical Stability

EVANOHMTM R alloys are engineered to maintain precise resistance values, even under fluctuating temperatures and operational stresses. This makes them highly dependable for applications requiring consistent electrical performance, such as precision resistors and temperature-sensitive devices. Their controlled composition delivers reliable results in critical environments.

Versatile Forms and Finishes

Available in coil, sheet, and wire, EVANOHMTM R offers flexibility for various design requirements. Choose from bright or dull finishes and a range of tempers, from annealed to hard (as rolled), to suit your specific manufacturing process and final application. Its adaptable dimensions also cater to custom project needs.

FAQ's of EVANOHMa R - DIN NiCr20AlSi(2.4872) | Electrical Resistance alloy:
