The invention aims to provide a magnetic conductive sleeve with high magnetic conductivity as well as a preparation method and application of the magnetic conductive sleeve. Comprising the following components of 15%-18% of chromium, 0.5%-4% of silicon, 0.2%-0.5% of nickel, 3.5%-5.75% of aluminum, 0.2%-0.6% of titanium, 0.3%-0.7% of yttrium oxide, 0.2%-0.3% of molybdenum, 0.1%-0.3% of manganese, 0.01%-0.3% of cobalt, 0.001%-0.1% of carbon and the balance iron and other inevitable impurities, and the content of the other inevitable impurities is smaller than 0.9%. The magnetic sleeve prepared by the components and the special preparation method is high in density and magnetic flux density, and has the characteristics of small overall thickness and high magnetic conductivity, and tests show that when the magnetic sleeve is applied to a conduit pump motor, 100% magnetic reflux can be met, meanwhile, the hysteresis phenomenon is avoided, the motor is smooth in running and starting, and the service life of the mot
