居里点高工作温度也同步提高，大路货 铝镍钴工作温度就有600摄氏度

It is an alloy composed of aluminum, nickel, cobalt, iron, and other trace metals. The casting process can be made into different sizes and shapes, with good workability. Casting Al-Ni-Co permanent magnets with high strength magnets have the lowest reversible temperature coefficient and can operate at temperatures up to 600 degrees Celsius.
您找个600摄氏度的液压油看看
【 在 xiaoju 的大作中提到: 】
: 永磁体用不着烧到居里温度就基本没磁性了，居里温度只是彻底消磁的节点
: 正好比铝合金也不用加热到熔点基本就没什么强度了
: 永磁电机和铝合金外壳面临的困难是同样的，温度200多度就完蛋。油可比磁铁耐折腾多了。
