Abstract

The invention discloses a high-performance copper-iron alloy material and an electroslag remelting preparation method thereof, and belongs to the technical field of non-ferrous alloys. The high-performance copper-iron alloy material is a copper-iron alloy electroslag ingot, and is composed of 4-20wt.% of Fe, 0.001-1.0wt.% of RE and the balance Cu, wherein RE is rare earth elements; RE is Ce and La, the content of Ce is 0.008-0.012wt.%, and the content of La is 0.05-0.06wt.%. The high-performance copper-iron alloy material is prepared by an electroslag remelting method, wherein a copper-iron alloy ingot smelted by a vacuum induction furnace is adopted as a consumable electrode, a CaF2-NaF slag system is adopted as a slag material, and the prepared copper-iron alloy electroslag ingot is uniform in chemical composition distribution, dense in structure and smooth in surface; the copper-iron alloy electroslag ingot can be used for continuous production of high-performance copper-iron alloywires.

Description

technical field [0001] The invention relates to the technical field of nonferrous metallurgy, in particular to a high-performance copper-iron alloy material and an electroslag remelting preparation method thereof. Background technique [0002] High-performance copper alloys are widely used because of their high strength, good plasticity and excellent electrical conductivity. Compared with Cu-Nb, Cu-Ag, Cu-Co and other copper alloys, Cu-Fe alloy has good advantages in large-scale industrial preparation and application due to its low cost, abundant raw materials, huge magnetoresistance effect and special physical properties. prospect. Copper-iron materials have both high electrical conductivity and high magnetic permeability, which can suppress or weaken electric and magnetic fields at the same time, and control the radiation propagation of electromagnetic waves from one area to another. Therefore, copper-iron alloy materials are ideal electromagnetic shielding functional ma...
