Products Overview
The automative grade high remanence tile magnet is a specialized ceramic-based magnetic component known for its high electrical resistivity, exceptional temperature stability, and robust corrosion resistance. Its wedge geometry is optimized for integration into circular magnetic assemblies or rotor systems where space-saving layout and consistent field distribution are essential. These high remanence tile magnets offer stable performance without surface plating and are ideal for applications requiring long-term operation in harsh or high-temperature environments.

Manufacturing Process of Arc-Shaped NdFeB Magnets
Arc-shaped NdFeB magnets are produced through a precisely controlled powder-metallurgy process to ensure high magnetic performance and dimensional accuracy, especially for motor applications.
Raw Material Preparation
High-purity neodymium, iron, and boron are carefully alloyed, with optional heavy rare earth elements added to enhance temperature stability.
Powder Milling
The alloy is crushed and jet-milled into fine, uniform magnetic powder under protective atmosphere, forming the basis for consistent magnetic properties.
Magnetic Alignment & Pressing
The powder is pressed in a strong magnetic field using arc-shaped tooling, aligning the crystal structure to achieve optimal magnetic orientation.
Vacuum Sintering & Heat Treatment
High-temperature sintering densifies the material, followed by heat treatment to stabilize the microstructure and magnetic performance.
Packaging Process & Instructions
- Sorting and inspection before packaging
- Mated wedge pairs aligned and packed to preserve orientation
- Vacuum sealed or shrink-wrapped for moisture control
- Internal partitions or foam to prevent chipping
- Cartons labeled with grade, quantity, and orientation
Application Fields
- Brushless DC Motors (BLDC): Segment rotor rings for consistent torque and magnetic balance
- Generator Rotors: Wedge layout for compact flux path control
- Magnetic Couplings: Torque transmission in chemical pumps
- Household Appliances: Motors in air conditioners, washing machines, etc.
- Automotive: Power steering, windshield motors, seat actuators
- Fan Blowers and HVAC Systems: Cost-effective and stable rotor design
Usage Precautions:
- Handle with care to avoid chipping; ferrite is brittle
- Avoid sudden temperature shocks post-sintering
- Store in dry environments away from alkaline substances
- Confirm proper polarity and wedge orientation before assembly

FAQ
Q1. Why do NdFeB magnets from different suppliers vary greatly in price?
Answer:Price differences are mainly influenced by raw material composition (especially heavy rare earth content), magnetic performance consistency, surface coating quality, dimensional tolerances, production yield, and quality inspection standards.
Q2. What do grades like N35, N42, or N52 actually mean?
Answer:The grade indicates the maximum energy product (BHmax). A higher number means stronger magnetic force, but also higher cost and often lower temperature resistance. Higher grades are not always the best choice for every application.
Q3. Why does magnetic strength slightly vary between production batches?
Answer:Minor variations can result from powder particle size, alignment accuracy, sintering conditions, and magnetization methods. Qualified suppliers control these variations within industry standards.
