    Flexible NdFeB Magnets Characteristics Flexible NdFeB Magnets Producible Range (mm)

    · Good flexible properties, virtually no cracking, no chipping (No cracks on the magnet when 1 mm thick sheet was wrapped around 10 mm diameter mandrel).
    · Highest magnetic properties, (BH)max come up to 80KJ/m3 in laboratory, the (BH)max (16～68KJ/m3 ) can be in mass production.
    · Temperature capability -40 deg.C to 120 deg.C.
    · Without complicated mold, so the cycle of production is short.
    · The capability for automatic installation, the installing efficiency is higher than that of the molded ring.
    · No need to change the production line and processes at the users' side. The same line/processes as for conventional sheet (flexible) magnets can be used.
    · Flexible magnetizing, low cogging due to magnetically isotropic characteristics.
    · Can be cut into long strips, narrow bars, large area thin sheets, thin rings to meet different demands.
