The mechanical properties of sintered Nd-Fe-B magnets：
|Bending Strength /MPa||Compression Strength /MPa||Hardness /Hv||Yong Modulus /kN/mm2||Elongation/%|
It can be seen that the sintered Nd-Fe-B magnet is a typical brittle material. During the process of machining, assembling and using of magnets, it is necessary to pay attention to prevent the magnet from being subjected to severe impact, collision, and excessive tensile stress, so as to avoid the cracking or collapsing of the magnet. It is noteworthy that the magnetic force of sintered Nd-Fe-B magnets is very strong in magnetized state, people should take care of their personal safety while operating, to prevent fingers climbing by strong suction force.
