SMagnetics adopts the most advanced production method to manufacture HAST (higher accelerated stress test) NdFeB, and reach the same level of VAC, SSMC and MQI.

Different from traditional sintered NdFeB, Hast NdFeB keeps a slight loss in weight and resists corrosion itself, thoroughly getting rid of reliance on coating. Hast NdFeB magnets widely apply to motors, magnet couplings etc. As per IEC HAST standard, SMagnetics Hast NdFeB magnet has only weight loss < 2mg/cm2 after exposed in high temperature, high pressure and high humidity cooker for 168hours, which is considered lifetime in motors will be over 10 years.

Hast NdFeB adopts special production method:
Strip casting—Hydrogen decrepitation—Automatic compacting-Continuous heat treatment to get perfect sole phase, guarantee whole process free from oxygen and end in high performance Hast NdFeB magnets.
Depending on unique technology, SMagnetics Hast NdFeB keep high corrosion resistance and reach the international top level.
