The invention discloses a brush wire with the high corrosion resistance and the high wear resistance. The brush wire comprises, by mass percentage, 8%-10% of Cr, 1.8%-3.2% of Mo, 1%-2.0% of Mn, 1%-3%of Fe, 0.2%-1% of Ti, 0.4%-1.5% of Al, 0.05%-0.1% of C, 1%-1.5% of Si, 0.2%-1% of Ni, 10%-15% of diamonds, 30%-35% of polyamide resin, 20%-25% of PBT resin, 10%-15% of fatty alcohol polyoxyethylene ether, 2%-5% of aminopropyl trimethylamino silane, 0.05%-1% of anti-wear agent, 0.05%-1% of lubricating agent, 0.05%-1% of temperature resisting agent, 0.05%-1% of plasticizer, 0.05%-1% of anti-aging agent, 0.05%-1% of antioxidant, 0.05%-1% of curing agent and 0.05%-1% of accelerant. Compared with the prior art, the brush wire has the advantages of being high in high temperature wear resistance, high in high temperature corrosion resistance, high in oxidation resistance, high in strength and the like, the service life of an engine brush seal can be effectively prolonged, the reliability of the engine brush seal can be effectively improved, a production technology of the brush wire is controllable, and batch production can be conducted.
