Compact Segmented Radial Arc NdFeB Magnet
1. Products Overview:
This strong magnetic force stable compact segmented radial arc ndfeb magnet depends on how it's manufactured and paired. It is shaped with a curved surface and appears to be precision-machined and possibly coated with Ni-Cu-Ni (nickel-copper-nickel) or another protective coating to prevent corrosion.
Magnet Type:
v Material: NdFeB (Neodymium Iron Boron)
v Grade (likely): N35–N52 depending on strength and heat resistance needs
v Shape: Arc or semi-elliptical block
v Coating: Likely nickel or epoxy for protection
2. Common Application:
This heat resistant super strong magnetic force stable compact segmented radial arc ndfeb magnet characterized by their curved shape and strong magnetic properties, are widely used in various applications, particularly in electric motors and generators. They are also found in medical devices, robotics, and industrial automation equipment. Their ability to generate a strong magnetic field with a reduced air gap between the magnet and the stator contributes to improved motor performance.

3.Manufacturing Process:
To enhance this strong magnetic force energy efficient stable compact segmented radial arc ndfeb magnet ‘s corrosion resistance, surface quality, and magnetic stability, the following treatments are used:
Edge Reinforcement: Laser cladding with nickel-based alloy at magnet seams (prevents electrochemical corrosion)
Edge Rounding: Reduces magnetic field distortion
Default Coating: Triple layer Ni-Cu-Ni (customizable)
Standard Thickness: Ni (3μm) + Cu (5μm) + Ni (4μm)
Optional Coatings: Gold or silver plating for better conductivity and corrosion resistance
Coating Benefits:
Salt spray resistance and improved oxidation durability
Higher surface hardness and scratch resistance
Enhanced gloss, suitable for exposed parts
Automatic Optical Inspection (AOI):
AOI stands for Automatic Optical Inspection — a vision-based technology used to inspect products for defects, dimensional inaccuracies, and surface flaws using high-resolution cameras and intelligent software.

Q: How to choose the correct magnetization direction?
Axial Magnetization: Magnetic lines flow through thickness — best for concentrated fields.
Radial Magnetization: Magnetic lines radiate outward — for uniform field distribution.
Multipole Magnetization: Multiple poles along circumference — for complex fields (e.g., motors, sensors).
Q: What is the maximum working temperature of a Segmented radial magnet?
Standard N-series: up to 80°C.
High-temp grades (SH/UH/EH): up to 150°C–230°C.
Dysprosium-enriched formulations can further enhance temperature resistance.
Q: Does magnetism decay over time?
Under normal conditions (room temp, dry, no heavy vibration), NdFeB magnets exhibit excellent time stability (<5% loss over 10 years). However, factors like:
Temperature overrun.
Strong external magnetic fields.
Surface corrosion.
Mechanical impact may affect performance.
