The paper reports a promising process of jointing magnetic alloy and electrical steel by means of linear friction welding. Linear friction welding method allows to create a precise connection of magnetic 25Х15К alloy and 10880 steel specimens providing vales of strength σ 0,2 =880 MPa and plasticity δ = 3 ± 1 % in the joint zone. Friction welding treatment results in formation of a solid connection without the diffusion zone due to short time of welding process. Mechanical testing at room temperature have shown that the compound demonstrates the values of strength and ductility comparable to ones of bulk 25Х15К alloy.
