Detailed Product Description
Compression bonded magnets offers higher magnetic strength than injection moulded magnets.
Bonded NdFeB magnets due to their higher magnetic partical density, but is limited to simple geometric shapes due to the compaction process. The epoxy coating is very resistant to normal industrial alovent and automotive fluids. The normal applications of these magnets rang from below -40℃ and beyong 165℃.
