Product Description
Neodymium Magnets N48 2 in x 1/4 in Disc
N48 Disc Magnets 2 in x 1/4 in – High-Strength Rare Earth Magnet for Precision Projects
Engineered for demanding applications, this N42 block magnet delivers extreme holding power in a compact, durable form. Its large size and high magnetic grade make it ideal for clamping, mounting, and fixturing in fabrication, manufacturing, and industrial tool setups.
Key Features:
- High-Strength N48 Grade: Stronger than N45, N42, and lower grades, delivering BrMax of 13,900 gauss for consistent, powerful magnetic force in demanding environments.
- Approx. 70 lbs Pull Force (Ideal Conditions): Delivers robust holding power when applied to clean, flat, uncoated steel surfaces at full contact. Performance may vary on painted, curved, or uneven surfaces.
- Large Surface Contact: The 2-inch diameter ensures stable attachment and alignment, ideal for sensor mounts and magnetic closures.
- Triple Layer Coating: Nickel-Copper-Nickel plating offers superior durability and corrosion resistance for long-term reliability.
- Magnetized Through Thickness: North and south poles are located on the two flat ends for secure and predictable surface contact.
Applications
This N48 magnet disc is perfect for:
- Sensor and instrument mounting
- Magnetic closure systems for cabinetry or electronics
- Industrial and workshop fixtures
- Wind turbine projects requiring low-profile magnets
- Educational kits and science demonstrations

Frequently Asked Questions (FAQ)
Is N48 grade suitable for strong industrial holding?
Yes, N48 provides strong holding power while balancing cost and performance, making it suitable for moderate to heavy-duty applications.
Can I use this outdoors?
The triple-layer coating offers excellent corrosion resistance, but for extended outdoor use, consider additional protection if exposed to harsh conditions.
How should this be mounted?
Use recessed slots, epoxy adhesives, or mechanical fasteners designed for magnets. Avoid high impacts to prevent chipping.
Performance & Usage Notes:
This N42 magnet is not designed for high-temperature environments. If your application involves heat above 176°F (80°C), consider using a high-temperature rated magnet such as N42SH or N52SH
Caution: Handle with care. Neodymium magnets are brittle and can chip or snap if allowed to collide. Keep away from pacemakers and electronics.
