Bonded NdFeB Magnet

• Strong magnetic power (Power-Index(1) = 6~7)
• Newest type of magnetic material with higher cost (Cost-Index(2) = 7~10)
• Isotropic(3)
• Produced by composition of rare-earth NdFeB magnetic powders embedded in thermoplastic and formed by injection moulding machining
• Hard, Non-brittle light weight; plastic-like magnet, able to be moulded to varieties of shapes e.g. thin ring, gears, arc-segments etc.; able to incorporate with shafts during manufacturing
• Excellent resistance to demagnetization
• Good temperature stability
• Good resistance to corrosion and chips
