一种钕铁硼永磁体用铜基钎焊材料及其制备方法
摘要：
本发明公开了一种钕铁硼永磁体用铜基钎焊材料，包括重量百分比的下述成分：稀土元素RE：5.0～15.0％，锌Zn：2.0～20％，硅Si：0.1～0.5％，银Ag：1.0～10％，余量为铜Cu。本发明针对钕铁硼永磁体的连接和组装需求，提供了一种钕铁硼永磁体用铜基钎焊材料，该铜基钎焊材料的熔化温度较低，对钕铁硼永磁体的润湿性好，且不会对钕铁硼永磁体的微观组织与磁性能产生不利影响；接头连接强度高、冲击韧性好，且具有较好的耐热性。
摘要（英）：

The invention discloses a copper-based brazing material for an NdFeB permanent magnet. The copper-based brazing material for the NdFeB permanent magnet comprises the following components of, by weightpercentage, 5.0-15.0% of RE, 2.0-20% of Zn, 0.1-0.5% of Si, 1.0-10% of Ag, and the balance Cu. The copper-based brazing material for the NdFeB permanent magnet is provided to meet the connecting andassembling requirements of the NdFeB permanent magnet. The smelting temperature of the copper-based brazing material is low, the wettability to the NdFeB permanent magnet is good, and no adverse influence is generated on the microstructure and magnetism of the NdFeB permanent magnet. Connector connecting strength is high, impact toughness is good, and good heat resistance is achieved.
