Neodymium Disc Magnets – N42 Grade: High-Strength Magnetic Precision from Magnitech

When your application demands high-strength, compact magnetic force with superior reliability, N42 Grade Neodymium Disc Magnets from Magnitech deliver the performance professionals trust. As one of the most popular and versatile neodymium magnet grades, N42 offers the perfect balance between maximum magnetic pull and material stability — making it ideal for demanding technical, industrial, and display applications.

At Magnitech, we offer a wide selection of N42-grade neodymium disc magnets, stocked and ready to ship across the UK with precision sizing and consistent quality.

What Is N42 Grade – And Why Does It Matter?

Neodymium magnets are categorized by grades — which represent their maximum energy product (measured in Mega Gauss Oersteds, or MGOe). The higher the grade, the stronger the magnetic field per unit of volume.

• N42 Grade means the magnet has a maximum energy product of 42 MGOe — offering excellent magnetic strength while maintaining cost-efficiency and stability.

• It provides 20–30% more strength than lower grades like N35, making it ideal for use in precision equipment, advanced assemblies, and tight-space applications.

Magnitech’s N42 disc magnets are particularly suitable for engineers, manufacturers, designers, and signage professionals who require strong, compact magnets that perform reliably over time.

Key Features & Benefits of Magnitech N42 Disc Magnets

✅ Powerful Magnetic Performance

The N42 grade offers superior holding force, capable of securing panels, components, or fixtures where strength is critical. Perfect for use where space is tight, but reliability can't be compromised.

✅ Compact Design with High Pull Strength

Even the smallest N42 disc magnets pack remarkable magnetic power. Their slim profile allows for discreet installation while maintaining a high pull-to-size ratio — ideal for hidden fastenings or space-constrained assemblies.

✅ Precision-Machined Sizes

Available in a wide range of diameters and thicknesses, with tight manufacturing tolerances to ensure uniform fit and performance — essential for automated production, batch runs, or technical builds.

✅ Durable Ni-Cu-Ni Coating

Each magnet is coated in a protective triple-layer plating of nickel-copper-nickel, offering:

• Corrosion resistance

• Enhanced surface hardness

• A clean, metallic finish ideal for visible or embedded use

✅ Excellent Resistance to Demagnetisation

N42 magnets have a strong coercive force, meaning they retain their magnetic field over time, even in harsh environments. Ideal for long-term installations in retail, industrial, or structural settings.

✅ Versatile Material Compatibility

Suitable for bonding, embedding, and mounting with a wide range of substrates including:

• Steel and iron

• Wood and composites

• Plastics and polymers

• Acrylic and signage materials

Common Applications

Magnitech N42 Disc Magnets are trusted across industries where compact power and accuracy are essential:

• Signage & Graphics: Secure signs, panels, or acrylic displays without visible fixings.

• Retail Fixtures: Create modular shelving or adjustable product displays.

• Engineering & Mechanical Design: Use in sensors, gears, motor assemblies, or enclosures.

• Cabinetry & Furniture: Concealed magnetic closures and fittings.

• Exhibition & POS: Fast, tool-free setups with clean, seamless presentation.

• Print & Packaging: Premium closures for boxes, folders, or presentation kits.

• Craft & Design Projects: Embedded into models, frames, and interactive products.

Wherever precision magnetic holding is required, N42 grade magnets deliver confidence.
