Neodymium Ball Magnets 12.7mm

12.7mm is an intermediate dimension for spherical rare earth neodymium magnets, it is also a popular size in the USA market. The pulling strength of N42 neodymium ball magnets of 12.7mm is about 2.7kg. Higher grades can be customized for greater force. Most 12.7mm neodymium sphere magnets bulk are plated with nickel or chromium, other plating (like as Au and Ag) can be customized. If two strong magnetic balls collide, the coating at the contact point will fall off due to the strong impact force. Do not let children play with the magnetic ball alone including neodymium magnetic balls 10mm and 5mm magnetic balls wholesale.

Characteristics Of N42 Neodymium Ball(Sphere) Magnets 12.7mm

Remanence (Br):  12.7mm neodymium magnet balls of grade N42 have remanence of 12800-13200 Gs.

Coercivity (Hcj): ≥955 KA/m.

Magnetic Energy Product (BHmax):  N42 sphere magnets wholesale of 12.7mm have a BHmax of 40-43 MGOe.

Max.Working Temp.: ≤80℃.

Common Coating : Cr and nickel are the common coating types for sphere neodymium magnets 12.7mm.

Neodymium Magnetic Balls 12.7mm Vs 7mm


  • Stronger Magnetic Force: The Neodymium Magnetic Balls 12.7mm offer a significantly stronger magnetic force compared to the 7mm magnetic balls, making them ideal for industrial applications that require robust holding power and stability.

  • Enhanced Durability: With a larger diameter, the 12.7mm magnetic balls are more durable and less prone to wear and tear, ensuring a longer lifespan and reducing the need for frequent replacements, which can save costs in the long run.

  • Versatile Applications: The increased size of the 12.7mm balls allows for a wider range of applications, from heavy-duty engineering projects to complex scientific experiments, providing greater flexibility and utility for various industries.

  • Improved Handling and Safety: The larger size of the 12.7mm neodymium magnetic balls makes them easier to handle and less likely to be accidentally ingested, enhancing safety during use and making them a more practical choice for both professional and educational settings.
