10x4mm Mini Round Heavy Duty Neodymium Magnets

Product Overview

The 10x4mm Mini Round Heavy Duty Neodymium Magnet is a compact, high-performance NdFeB disc designed to deliver exceptional holding force where space is limited. These mini round magnets combine a powerful magnetic pull with a durable Ni-Cu-Ni finish, making them suitable for electronics, robotics, hobby projects, and small fixtures.

Key Features

• High magnetic strength from premium neodymium-iron-boron (NdFeB) material
• Compact dimensions: 10 mm diameter x 4 mm thickness
• Round disc shape with axial magnetization for uniform field and easy mounting
• Ni-Cu-Ni (nickel) plating for enhanced corrosion resistance and longevity
• Heavy duty grade designed for reliable holding, fixing and alignment tasks

Technical Specifications

• Type: Neodymium Magnet (NdFeB)
• Shape: Round / Disc
• Diameter: 10 mm
• Thickness: 4 mm
• Magnetization: Axially magnetized
• Coating: Nickel (Ni-Cu-Ni)
• Grade: Heavy Duty / High Strength

Applications

These 10x4mm neodymium magnets are ideal for a wide variety of uses including:

• Electronics and PCB mounting solutions
• Robotics and automation assemblies
• DIY, maker and hobby projects
• Crafts, art and model making
• Magnetic closures, holders and small fixtures
• Educational demonstrations and experiments
• Small tool attachment and alignment applications

Advantages

• High pull force in a small footprint allows fewer or smaller magnets to be used
• Long-lasting Ni-Cu-Ni finish improves corrosion resistance in many environments
• Consistent performance in repeated use and secure holding for assemblies
• Easy to integrate into designs because of round disc shape and axial magnetization

Safety and Handling

• Always handle with care; strong attraction can cause magnets to snap together and pinch skin
• Keep away from children and pets due to ingestion and injury risk
• Keep magnets away from pacemakers, credit cards, magnetic storage media and other magnetic-sensitive devices
• Avoid exposing magnets to high temperatures, mechanical shock, or drilling which can damage magnetic properties

Installation and Mounting Tips

• Use adhesives rated for metal when bonding magnets to surfaces where mechanical fasteners are not possible
• Design housings or recesses to tightly fit the 10x4mm disc to prevent movement and improve holding strength
• When mounting on ferrous surfaces, allow for reduced field strength if other metal parts partially shield the magnet

Ordering and Packaging

Available in single pieces or bulk packs. For multiple magnet assemblies, consider magnetic polarity and spacing to achieve the desired holding or repulsion effect. Contact us for bulk pricing or custom packaging options.
