Sphere Magnet is an alloy magnet that maily comprises the Neodymium,Iron and Boron Metal,
The manufacturing engineering of NdFeB makes use of process of powder metallurgy such like alloy powder being pressed inthe magnetic flux and being sintered in the vacuum furnace or inertgases environment so that the magnets possibly have high coerciveforce,high product energy ,high performance price ratio and favorable mechanicalness.
maybe you will be puzzled to search manufacturers,who can provide high quality ndfeb and motor magnet, there are all you need,we have annual capacity of 1000 tons per year, and we have developed international market in USA,Germany,Asia,India and so on ,the customer give our high praise. if you need ,please contact us.
