Due to the strong magnetic force of NdFeB magnetic material, it is widely used, but the price of the material has been rising year by year in the past two years, which has caused certain cost pressure to some enterprises that use a large number of magnets and small and medium-sized NdFeB manufacturers. Some netizens Can't help but ask, will NdFeB be replaced by other magnetic materials.
What magnets can replace neodymium strong magnets?
N52 6mm x 6mm cylinder neodymium magnet 4820 gauss
It is understood that some motor manufacturers have begun to modify the design of their products. The number of Nd-Fe-B magnets used in motor equipment is decreasing. For products in middle and low-end industries, they prefer to choose ferrite (ceramic) magnets with lower prices.
For some terminal industries that have high requirements for magnet performance, such as wind power generation, high-speed motors, new energy vehicles and parts, energy-saving inverter air conditioners, energy-saving elevators, and intelligent robot manufacturing, NdFeB cannot be replaced temporarily, and There are no better alternatives in the short term.
Summary;
Magnets used in some middle and low-end fields, such as packaging, handbags, luggage buckles and toys, can indeed be replaced, while neodymium iron boron, which has strict requirements on magnet performance, cannot be replaced for the time being, and better magnetic materials cannot be found to replace them in the short term.
