The listed 73.66 lb pull-force value is a comparison/test value and should not be used as a universal safe working load. Actual holding performance depends on the steel target, contact area, air gap, surface finish, alignment and whether the load is normal, shear or peel.
For applications with sufficient package space, large ferrite blocks can provide an economical alternative to rare-earth magnets while avoiding the plating requirements common with sintered NdFeB.
