Materion R270 Resistor Alloy is a Copper-Manganese-Nickel alloy with low resistivity and very low Thermal Coefficient of Resistance (TCR). Commonly used for precision resistors, R270 is produced using a patented casting process, which produces homogeneous alloying and consistent, stable performance. Compare with Manganin®. Available forms include wire, formed wire, strip, and sheet.Information provided by Materion. |
