LOW-COST NANO-COMPOSITE PERMANENT MAGNET CONDUCTIVE CONTACT AND MANUFACTURING METHOD THEREFOR

摘要

A low-cost nano-composite permanent magnet conductive contact and a manufacturing method therefor. The permanent magnet conductive contact is composed of three parts: a fixed sleeve, a core body, and a coil; the core body is a composite core body obtained by taking an alloy formed by mixing the raw materials in parts by weight of 6-8 parts of lanthanum, 3.5-4.5 parts of cerium, 100-110 parts of ferroboron FeB22C0.05, and 5-7 parts of yttrium as a core and taking pure copper as a housing, and the composite core body is sleeved in the fixed sleeve; the coil is formed by winding an aniline modified carbon fiber aluminum core composite wire wound on the surface of the core body, and the coil is wound on the inner surface of the fixed sleeve. The present solution is low in cost, only uses abundant rare earth, is high in magnetic energy product, and is rapid in shaping.
