N48SH Neodymium Iron Boron Permanent
Magnet: High-Performance Rare Earth Magnet for Advanced Engineering Applications This premium N48SH neodymium iron boron (NdFeB) permanent magnet represents the pinnacle of rare earth magnetic technology, engineered for industries demanding superior energy efficiency and robust performance. As a high-grade sintered rare earth magnet, it delivers exceptional magnetic strength, making it ideal for applications where space constraints and power density are critical. With its optimized balance of remanence and coercivity, this material ensures stable operation under extreme conditions—whether in high-temperature environments or dynamic mechanical loads. Key Features: - Exceptional magnetic flux density (remanence) exceeding 1.4 Tesla - High intrinsic coercivity (Hci > 1200 kA/m), enabling resistance to demagnetization - Available in multiple surface treatments including nickel plating, black nickel, black epoxy coating, and phosphating for enhanced corrosion resistance and aesthetic appeal - Customizable shapes, sizes, and magnetization patterns tailored to specific engineering needs - Consistent quality across batches, supported by rigorous ISO-compliant manufacturing processes The N48SH grade is part of the broader family of
Sintered Ndfeb Magnets known for their superior performance-to-weight ratio. Unlike traditional ferrite or alnico magnets, these rare earth materials offer up to 10x higher energy product, allowing designers to reduce component size while increasing output efficiency. This makes them indispensable in modern electric motors, generators, sensors, and actuators. The material’s thermal stability is further improved through specialized alloying elements such as dysprosium and terbium, which enhance coercivity without compromising remanence—a key factor in high-temperature motor applications like EV traction systems and industrial robotics. Common Use Cases: - Electric vehicle motors and drivetrains requiring compact yet powerful solutions - Wind turbine generators benefiting from efficient energy conversion at low rotational speeds - Industrial automation equipment such as servo motors and linear actuators - Medical devices including MRI components and surgical tools relying on precise magnetic control - Consumer electronics like headphones, speakers, and smartphone vibration motors - Aerospace and defense systems needing lightweight, high-strength magnetic assemblies User Feedback: "Switching to N48SH magnets significantly boosted our motor’s torque output while reducing overall weight—an essential upgrade for our drone design." "Reliable performance even after 6 months of continuous operation in harsh outdoor conditions. The black epoxy finish prevented rust effectively." "We were impressed by how quickly they responded to our custom magnet request—it was delivered ahead of schedule with no compromise on quality." Frequently Asked Questions: What sets N48SH apart from other NdFeB grades?
