Claim:
1. A method of rolling NiW alloy tape for coated conductors, comprising the following steps: rolling back and forth a cylindrical NiW alloy ingot with a diameter not less than 10 mm along an axis of the ingot, wherein the content of W is 5˜7 at. % and the axis of the ingot is perpendicular to a plane where axes of working rollers are placed; and during the process of rolling the cylindrical NiW alloy ingot, cross sectional area reduction of the ingot is retained at 4-6% per pass; and the rolling is stopped when a total cross sectional area reduction of the ingot is larger than 98% and the thickness of the tape is down to 60˜100 μm, and thus the NiW alloy tape is obtained.
