What is a Neodymium Channel Magnet?
A channel magnet refers to a magnetic assembly where neodymium (NdFeB) magnets are embedded in steel or aluminum channels. These rare earth channel magnets combine the extreme strength of grade N35-N52 neodymium with structural support for industrial applications.
Ideal for mounting systems, sensors, and automation equipment requiring both magnetic strength and mechanical protection.

NdFeB magnets are not as heat-resistant as Alnico magnets, which can withstand temperatures of 450 to 550 °C. NdFeB magnets generally withstand temperatures of around 80 to 220°C.
We can provide zinc coating, nickel coating, chemical nickel, black zinc and black nickel, epoxy, black epoxy, gold coating etc...
The magnetic field of each shape of magnet is different. We can customize the shape and magnetization direction to meet customer requirements.
Professional Knowledge & Buying Guide for Industrial Buyers
Mechanism of Groove Structure in Magnetic Field Concentration and Force Enhancement
● Magnetic Field Concentration: Grooved structures can concentrate magnetic field lines near the slots, reducing dispersion and creating a stronger localized magnetic field.
● Enhanced Magnetic Force: The edges of the slots generate a more intense magnetic field, increasing strength by 30%-50% compared to flat magnets, making them ideal for high-force applications.
● Optimized Design: Grooves can be paired with multi-pole magnetization to minimize magnetic leakage, though they require more complex machining and cost considerations to balance performance and durability.
How to Choose the Right Coating for Channel Magnets?
● Nickel: General choice, rust and wear resistant, bright silver appearance,Corrosion resistant coating
● Epoxy: Black or gray, suitable for wet/chemical environments
● Zinc: low cost, but not as corrosion resistant as nickel
● Gold / Chrome: Can be used for medical devices or high-end decorative parts
Recommendations for Different Usage Environments of Channel Magnets
● Indoor Environments (Stable Temperature/Humidity)
Recommended Treatment: Nickel Plating (Ni-Cu-Ni)
Advantages: Cost-effective, glossy finish, prevents oxidation. Ideal for electronics and precision instruments.
● Outdoor/High-Humidity Environments (Rain, Moisture)
Recommended Treatment: Epoxy Resin Coating (Black/Gray)
Advantages: Excellent corrosion resistance, withstands salt spray. Suitable for marine equipment and outdoor sensors.
● High-Temperature Environments (80°C+)
ecommended Treatment: Phosphating + High-Temp Epoxy Coating
Advantages: Heat-resistant (150-200°C), prevents thermal oxidation. Used in motors and automotive components.
● Strong Acid/Alkali or Chemical Corrosion Environments
Recommended Treatment: PTFE (Teflon) Coating
Advantages: Chemical-resistant, electrically insulating. Ideal for medical and chemical equipment.
How to Choose Channel Magnet Size, Magnetic Grade and Magnetization Direction According to Application Requirements?
Determine Size Based on Space and Force Requirements
First match the installation space (e.g., motor slot size), then adjust thickness according to magnetic force needs:
- Small gaps: Use thin models (1.5–5mm)
- Strong force needed: Choose thicker versions (5–30mm)
Select Magnetic Grade by Application Scenario
- General use:(e.g., household magnetic holders): N35–N42 (cost-effective)
- Industrial/high-power:(e.g., motors, medical devices): N45–N52 (heat-resistant/strong force)
- High-temperature environments: Choose "H/SH" suffix models (e.g., N38SH)
Choose Magnetization Direction Based on Motion Type
- Static adsorption: Axial magnetization (single-side force)
- Rotating equipment: Radial magnetization (e.g., motor rotors)
- Precision control: Multi-pole magnetization (reduces eddy current loss)
Quick rule: Size by space, grade by scenario, direction by motion.
Usage Strategies for Neodymium Channel Magnets in High-Temperature and Special Operating Conditions
Phenomenon
High temperatures disrupt the alignment of magnetic domains, causing complete demagnetization if the Curie temperature is exceeded, and performance degradation even below it.
Influencing Factors
- Material heat resistance (e.g., NdFeB has low tolerance, SmCo has high tolerance).
- Temperature fluctuations accelerate aging.
Prevention
- Use high-temperature-resistant materials (e.g., SmCo).
- Enhance heat dissipation (heat sinks/cooling fans).
- Avoid overheating during operation.
Standard Pull Force Test Method and Key Considerations
Test Method
Use a calibrated tensile tester with a non-magnetic fixture.
Gradually increase vertical pull force until magnet detaches from the test surface.
Record peak force value as pull force (N or kgf).
Critical Factors
Surface condition: Test plate material/surface finish must match application specs (e.g., steel D36, Ra≤1.6μm).
Contact area: Ensure full contact with zero air gaps.
Separation speed: Maintain 5-10 mm/s steady pull rate.
Precautions
Perform 3-5 repeated tests for averaging.
Demagnetize test plates between trials if testing multiple magnets.
Document ambient temperature (affects NdFeB magnets' performance).
Customization Guide – How to Communicate Efficiently with Suppliers
● Dimensional drawing or specification (with Dimensional unit)
● Material grade requirements (e.g. N42 / N52)
● Magnetization direction description (e.g. Axial)
● Surface treatment preference
● Packaging method (bulk, foam, blister, etc.)
● Application scenario (to help us recommend the best structure)
