This is big square magnet, the material is sintered ceramic ferrite, the grade is y30bh. The specific size is 100mm in length and width, 15mm in thickness. It can resisit a high temperature up to 250℃, but the magnetic force is not good as neodymium. If you wanna the better magnetic force and the working temperature is less than 230℃, you can choose neodymium magnet.
