High-temperature and high-elasticity alloy wire for brush type sealing and preparation method of high-temperature and high-elasticity alloy wire

The invention discloses a high-temperature and high-elasticity alloy wire for a brush seal and a preparation method thereof, belongs to the technical field of alloy materials, and solves the problem of short service life of the brush seal due to poor obdurability of the brush seal alloy wire in the prior art. The high-temperature high-elasticity alloy wire for brush sealing comprises the following chemical components in percentage by mass: less than or equal to 0.01% of C, 1.50-2.50% of Mn, 0.10-0.20% of Si, less than or equal to 0.01% of P, less than or equal to 0.01% of S, 14.50-16.50% of Cr, 3.50-4.50% of Fe, 4.00-6.00% of Al, 0.005-0.01% of Y, 0.05-0.10% of Zr, 0.005-0.01% of B, less than or equal to 0.001% of Pb, less than or equal to 0.0001% of Bi, less than or equal to 0.0001% of Ag, less than or equal to 0.002% of N, less than or equal to 0.002% of O and the balance of Ni and inevitable impurities. The high-temperature high-elasticity alloy wire for the brush seal has excellent strength and toughness,
