How to identify NdFeB and AlNiCo magnet ?

- Nov 06, 2017 -

    Neodymium iron boron are basically electroplating ZN or NI and NdFeB magnetic strength than Alnico strong, Alnico under normal circumstances does not require surface plating, because the product itself is good corrosion resistance. Table plating or not is very easy to identify. And the fracture of the two products is not the same. NdFeB is a very fine small crystals, while the AlNiCo section is significantly more rough, crystal particles larger.
