Product Description

Neodymium Magnets N45 Block 1 in x 1/2 in x 1/8 in

Neodymium N45 Block 1 in x 1/2 in x ⅛ Magnets in – Strong Rare Earth Magnet for Compact Precision Applications

This N45 grade block magnet is designed for projects requiring reliable strength in a slim, compact footprint. Measuring 1 inch x 1/2 inch x 1/8 inch, this rare earth magnet provides extreme holding force while maintaining a low profile, making it ideal for precision mounting, sensor assemblies, and secure closures in tight spaces.

Key Features:

• Compact Rare Earth Block Magnet: Slim 1" x 0.5" x 0.125" dimensions provide a stable contact area with a low profile for flush mounting in projects.
• High-Strength N45 Grade: Stronger than N42, N40, N38, and N35 grades, delivering a BrMax of 13,800 gauss for consistent, powerful performance.
• Estimated Pull Force: Rated for up to 12 lbs under ideal conditions (clean, flat steel). Actual holding force may be lower depending on surface type, alignment, or coatings.
• Max Operating Temperature: Rated for continuous use up to 80°C (176°F). Exposure above this temperature may permanently reduce magnetic strength.
• Triple Coated: Nickel-Copper-Nickel plating for excellent corrosion resistance and long-term durability, even in workshop or light outdoor settings.
• Magnetized Through Thickness: North and south poles on the 1" x 0.5" surfaces, providing reliable alignment for your assemblies.
• Corrosion Resistance: Triple-layer Nickel-Copper-Nickel coating provides good resistance to moisture and light outdoor use, but not recommended for prolonged exposure to rain, saltwater, or highly corrosive environments.

Frequently Asked Questions

How strong is the N45 grade magnet?
N45 neodymium magnets offer a strong magnetic field and holding force, stronger than N42, N40, N38, and N35 grades, making them ideal for applications requiring a balance of power and affordability.

What coating does this magnet have?
It features a Nickel-Copper-Nickel triple-layer coating, providing excellent durability and corrosion resistance for long-term use in various environments.

Can this magnet be used for sensor and small instrument mounting?
Yes, its compact size and reliable strength make it ideal for mounting sensors, small instruments, and other lightweight components securely.

What precautions should I take when handling this magnet?
Handle with care to avoid pinching fingers or chipping the magnet. Keep away from electronics and pacemakers, and store in a secure location to prevent accidental collisions with other magnetic materials.

Can this magnet be used outdoors?
The triple-layer coating provides good corrosion resistance for light or occasional outdoor use. Avoid prolonged exposure to rain, saltwater, or acidic conditions, which may damage the magnet or reduce performance.

What is the maximum temperature for these magnets?
N45 magnets can be safely used up to 80°C (176°F). Higher temperatures may permanently reduce magnetic strength.

Safety Note:

These magnets are extremely strong and may snap together unexpectedly, which can cause pinching or chipping. Handle them carefully, keep them away from children and sensitive electronics, and always follow safety guidelines during handling and installation.
