Product Description
N48 Strong Neodymium Magnets 4 in x 2 in x 2 in Rare Earth Block
N48 Neodymium Magnets 4 in x 2 in x 2 in Block – Extra-Large High-Strength Rare Earth Magnet for Industrial and Heavy-Duty Applications
Engineered for maximum holding force across a large contact area, this N48 magnet (4 inch x 2 inch x 2 inch) is designed for industrial, workshop, and heavy-duty uses requiring extreme strength. Its substantial size and powerful N48 grade make it ideal for lifting, secure fixturing, magnetic separation, and heavy-duty closures where reliable, high pull force is essential.
Key Features:
- Large Rare Earth Block Magnet: 4-inch x 2-inch x 2-inch dimensions provide extensive surface contact for maximum stability in industrial applications.
- High-Strength N48 Grade: Delivers a BrMax of ~14,200 gauss, providing superior magnetic strength while balancing cost-effectiveness for heavy-duty uses.
- Estimated Pull Force: Capable of holding hundreds of pounds under ideal conditions only (pull force varies based on surface contact, thickness, and environment).
- Triple Coated: Nickel-Copper-Nickel plating offers excellent corrosion resistance and durability, even in industrial or workshop environments.
- Magnetized Through Thickness: North and south poles on the 4" x 2" faces for secure alignment in your heavy-duty assemblies.
- Typical Heat Rating: N48 magnets generally have a maximum operating temperature of 80°C (176°F). Exceeding this may cause a reduction in magnetic strength.

Frequently Asked Questions
How strong is this N48 magnet compared to other grades?
N48 is a high-grade neodymium magnet, stronger than N42 and N45, providing excellent magnetic force while balancing affordability for industrial uses. For absolute maximum strength, N52 is stronger, but N48 remains extremely powerful for most heavy-duty needs.
Can this magnet be used for lifting heavy objects?
Yes, this magnet’s large contact area and high-grade N48 strength make it suitable for lifting and material handling applications under controlled conditions. Always test in your environment for precise lifting capabilities and follow all safety guidelines.
What coating does this magnet have?
It features a Nickel-Copper-Nickel triple-layer coating, providing strong corrosion resistance and durability in workshop and industrial settings.
What precautions should I take when handling this large magnet?
Due to its extreme strength, this magnet can pinch fingers or shatter if it collides with metal or another magnet. Handle with caution, wear protective gloves if needed, keep away from electronics and pacemakers, and never allow children near these magnets.
Safety Note:
Handle with care, keep away from children, pacemakers, and sensitive electronics, and review safety guidelines before use.
