Welcome to Magtech

Rare-earth Neodymium Magnet, Sintered

• Strongest magnetic power (Power-Index(1) = 10)
• Excellent Cost-to-Performance ratio (Cost-Index(2) = 5~7)
• Anisotropic(3)
• Produced by powder metallurgical engineering with chemical composition of Nd2Fe14B
• Brittle & hard
• High resistance to demagnetization
• Good temperature stability
• Require surface treatment to prevent corrosion
