* Grade: A , a general description for
a good quality of the products. Strong Magnet Co always insists to supply A Grade.
* The surface gauss value doesn't mean high magnetic force, the magnetic force depends on the size of magnets and the magnetic material grade. Small size magnet used to have high surface gauss value, but the magnetic force is less. To compare the magnetic force according to gauss value, it is only for the magnets which have the same shape and size.
