Product Overview
This stable high remanence bar magnet is a high-performance permanent magnet made from advanced rare earth NdFeB (Neodymium-Iron-Boron) materials, known for their outstanding magnetic properties and exceptional strength. With a sleek, nickel-plated finish, this industrial grade high remanence bar magnet offers both strong magnetic performance and excellent corrosion resistance, making it ideal for a wide variety of demanding industrial and commercial applications.
Key Features & Performance
High Magnetic Strength:
Made from premium-grade NdFeB (available in N35–N52), these magnets deliver some of the highest magnetic forces available, ensuring reliable performance even in compact sizes.
01
Durable Nickel Plating:
The triple-layer Ni-Cu-Ni (Nickel-Copper-Nickel) coating significantly improves corrosion resistance and enhances surface durability, providing long-term stability even in harsh or humid environments.
02
Precision Tolerances:
Manufactured with advanced CNC and fine grinding technology, each magnet maintains strict dimensional tolerances for consistency, easy integration, and reliable assembly in automated processes.
03
Versatile Shape:
The rectangular bar shape maximizes contact surface area, making these magnets suitable for linear force, holding, sensing, and positioning applications.
04
Customizable Specifications:
Size, grade, magnetization direction, and coating can be customized to meet your unique project or application requirements.
05
Reliability Test
● Thin-wall Anti-crack Technology: Ultrasonic-assisted cutting to reduce cutting stress; cryogenic processing to prevent material cracking.
● Grain Boundary Diffusion Technology: Surface coating with dysprosium compounds to improve coercivity.
Appearance and Dimensional Inspection Standards
To guarantee the reliability, dimensional accuracy, and long-term performance of this custom-engineered, high-performance rectangular NdFeB magnet, each production lot is subjected to comprehensive quality verification, including:
▼ Appearance and surface integrity inspection
Conducted by trained inspectors under controlled illumination conditions (approximately 800–1200 lumens) at defined observation distances to identify cracks, chipping, surface defects, or oxidation.
▼ Precision dimensional verification
Advanced 2D optical measurement systems are employed to accurately inspect critical dimensions, especially for complex geometries or non-standard magnet designs, ensuring strict compliance with tolerance requirements.
Packaging & Transportation
Defect Sorting:
Dimensional and appearance defects are removed before final packaging.
Vacuum Packaging:
Prevents moisture ingress and magnetic interference during shipping.
Outer Packaging:
Shock-resistant, moisture-proof, and anti-magnetic packaging ensures safe transportation.
Typical Applications
Industrial Automation:
Fixtures, jigs, robotic arms-ring design allows secure screw fastening for precise positioning.
Tools & Equipment:
Positioning of electric tool components, removable magnetic covers, and instrument panels.
Sensors & Detection Devices:
Magnetic sensors, reed switches, and position detectors.
Medical & Electronic Devices:
Mounting of portable medical equipment and electronic modules-strong magnetic force without interfering with sensitive electronics.
