Abstract

The invention discloses a nickel chrome wire. The nickel chrome wire is made of an alloy material, and the alloy material comprises 1% to 2% of P, 1.5% of Si, 2.2% of Cu, 0.8% of Mn, 0.9% of In, 14.5% of Cr and the balance Ni and inevitable impurities. The alloy material is prepared through the following steps: firstly, Ni, P, an Ni-Si alloy and an Ni-Cu alloy are molten under the protective atmosphere; secondly, the temperature is adjusted to 900 DEG C, an Ni-Mn alloy, an Ni-In alloy and an Ni-Cr alloy are added into a melt and are evenly stirred, and the melt is subject to heat preservation and standing for 25 minutes; and thirdly, argon is led, the melt is subject to standing and is cooled to 600 DEG C, and pressure casting is carried out, so that the alloy material is obtained. The nickel chrome wire has the higher specific resistance, is good in surface oxidation resistance and high in temperature level and has the higher strength at the high temperature.
