8x3mm Mini Round Heavy Duty Neodymium Magnets

8x3mm Mini Round Heavy Duty Neodymium Magnet — Product Overview

The 8x3mm Mini Round Heavy Duty Neodymium Magnet is a small yet powerful permanent magnet made from premium neodymium-iron-boron (NdFeB). Designed to deliver superior magnetic force in a compact form factor, this magnet is ideal for precision applications in electronics, robotics, crafts, model making, and educational projects where space is limited but performance matters.

Key Features of the 8x3mm Mini Round Neodymium Magnet

• High magnetic strength: Premium NdFeB material provides much stronger attraction than ferrite or ceramic magnets of similar size.
• Compact and slim: 8 mm diameter with only 3 mm thickness for discreet, low-profile installations.
• Round disc shape: Even magnetic field distribution and easy positioning in assemblies.
• Durable nickel coating: Ni-Cu-Ni plating gives corrosion resistance and long service life.
• Heavy duty performance: Reliable holding, alignment, and repeatable use in demanding tasks.

Advantages of Using 8x3mm Mini Round Neodymium Magnets

• Strong magnetic pull despite the slim thickness, enabling secure holding in tight spaces
• Compact size for discreet integration into designs
• Corrosion-resistant nickel plating increases longevity
• Consistent and reliable magnetic performance for repeated use

Safety and Handling

• Handle carefully; magnets can snap together forcefully and pinch skin.
• Keep away from children and people with pacemakers or other sensitive medical devices.
• Avoid exposing magnets to high temperatures, drilling, or mechanical impact which can reduce strength or cause breakage.

Ordering, Availability, and Notes

Available in single units and bulk packs depending on stock. These magnets are a cost effective solution when you need maximum holding power in a minimal footprint. For higher temperature requirements or different coatings, consider alternative grades and finishes.
