Best Neodymium Magnet Block 50x25x10

The 50×25×10 mm Neodymium Block Magnet is a precision-engineered NdFeB block tailor-made for industrial and OEM applications. With a high-grade N52 alloy and compact 50 × 25 × 10 mm dimensions, this magnet delivers excellent flux density while fitting into tight assemblies. It is widely used by motor manufacturers, fixture designers, and automation engineers who require both power and dimensional stability in bulk.

• Magnetization Direction: Through 10 mm thickness, opposite faces are north/south 
• Coating: Ni‑Cu‑Ni (nickel-copper-nickel) for corrosion resistance 
• Certifications: ISO9001, TS16949, RoHS, SGS 
• Max Pull Force: Can support up to ~78 lbs (~35 kg) in flush contact with mild steel surface 
• Demagnetization Resistance: Excellent residual stability per manufacturer spec

• High Magnetic Power in Compact Size: Despite its small block form, this magnet offers strong magnetic pull, making it ideal for positioning, retention, and actuator modules.
• Stable Polarity & Precision: The through-thickness magnetization ensures well-defined pole faces, which is critical for machining fixtures and motor subassemblies.
• Durable Coating: The Ni‑Cu‑Ni plating protects against oxidation, prolonging lifespan in industrial environments.
• Typical Uses:
• Electric motor rotors or stator inserts
• Magnetic chucks or clamp fixtures
• Sensor assemblies and linear actuators
• High-precision tooling and multipart jigs

• Bulk & Custom Magnet Solutions: We support bulk orders for large-scale manufacturers and custom magnet designs based on your CAD or drawing.
• Quality Consistency: Every batch undergoes magnetic flux testing, dimensional inspection, and coating verification to ensure repeatable performance.
• Cost Efficiency: The block geometry allows for minimal waste and efficient integration, reducing downstream machining or material cost.
• Long-Term Reliability: With high coercivity and a protective coating, our magnets resist demagnetization and corrosion in demanding environments.

Each magnet is carefully wrapped with anti-magnetic separators and placed into magnet-safe cartons to prevent surface damage. For large or repeat orders, we offer custom packaging options like foam inserts or labeled trays. This ensures safe transit and easier storage in your warehouse.

• Magnetic flux (Br) and field measurements for every batch
• Dimensional tolerances verified to ± 0.1 mm or better
• Coating adhesion and corrosion resistance tests
• Full traceability: batch numbers and inspection reports are provided with every shipment
