钐铁氮磁粉

SmFeN Magnet Powders

产品介绍

钐铁氮磁粉适宜以注射、模压、挤出、压延、3D打印等工艺方法制备各种形态的新型高性能稀土粘结磁体，其突出特点在于磁性能高、磁性均匀、机械强度高、成型工艺灵活、涡流损耗小、能量转化效率高。磁粉平均粒径小，抗氧化和抗腐蚀能力较强。该磁粉最大磁能积为33-38MGOe，剩磁为13.5-14.7kGs，内禀矫顽力为9.0-11.0kOe，x50为1.9-2.3μm。同时，公司也可根据客户需求，提供特定物理特性（如粒度）和不同磁性能指标（如最大磁能积、剩磁、内禀矫顽力等）的磁粉。

SmFeN magnet powders can be flexibly processed into various shaped high performance bonded magnets via a variety of adhesive and molding techniques such as injection molding, calendaring, extrusion, compression and 3D printing. The magnets exhibit well-distributed and superior magnetic properties, high mechanic strength, flexible-molding, low eddy current loss and high energy conversion efficiency. The powders present small average particle size and enhanced anti-oxidation ability and corrosion resistance. The powders have (BH)max between 33-38MGOe, Br between 13.5-14.7kGs, Hcj between 9.0-11.0kOe, and x50 between 1.9-2.3μm. Magvalley can deliver SmFeN magnet powders with specific physical properties (e.g. particle size) and magnetic properties (e.g. BH(max), Br, Hcj) to cater to specific client needs.
