This is square neodymium magnet with holes(screw holes), also known as a square counter-bore magnet. The product is made of sintered Ndfeb, which is a rare earth element. If you need ferrite as a material, we can make it, but magnetism of NdFeB will be better than ferrite. The specific size is 45mm in length and width, 9mm in thickness, 8mm in hole(1 3/4" x 1 3/4" x 3/8"). The tolerance is±0.05mm, the surfacing coating color is silvery white, the working temperature is 80-200℃。
