The invention discloses a steel strip with good corrosion resistance and weldability for a brake oil pipe and a manufacturing technology of the steel strip. The steel strip comprises a steel strip base material, the two surfaces of the steel strip base material are provided with copper layers with a thickness of 3.0-3.6 micrometers in a plating mode, the nickel layer with the thickness of 0.5-1.0 micrometers are arranged on one surface of the copper layers in a plating mode, wherein the nickel layer is uniform, and the performance of the product is stable after the steel strips are bound with each other to form a tube. The steel belt for the brake oil pipe has the advantages that the production technology of the brake oil pipe is simplified, the production efficiency is greatly improved, and the discharge of the heavy metal nickel can be reduced.
