Abstract

Official abstract text for this publication.

Provided is a copper-manganese-nickel based alloy having characteristics (in particular, specific resistance) close to those of a nickel-chromium based alloy. It is also an objective to provide an alloy having high processability compared to a nickel-chromium based alloy. An alloy for a resistive body includes copper, manganese, and nickel, wherein the manganese is 33 to 38% by mass, and the nickel is 8 to 15% by mass.

First claim

Opening claim text (preview).

1 . A resistive body alloy comprising copper, manganese, and nickel, wherein: the manganese is 33 to 38% by mass; and the nickel is 8 to 15% by mass. 2 . The resistive body alloy according to claim 1 , having a specific resistance of 117 to 143 μΩ·cm. 3 . The resistive body alloy according to claim 1 , having a Vickers hardness of 200 HV or less. 4 . The resistive body alloy according to claim 1 , comprising 0.5% by mass or less of tin, or 0.5% by mass or less of iron. 5 . Use of the resistive body alloy according to claim 1 in a resistor.
