Rare-Earth Neodymium Block Magnets

Neodymium bar, block, and cube magnets are well suited for applications requiring exceptional pull strength and longevity. As the strongest permanent, rare earth magnets commercially available today, neodymium magnets have magnetic properties that far exceed other permanent magnet materials. Because of their exceptional magnetic strength, resistance to demagnetization, low cost, and versatility, neodymium block magnets are a reliable choice for all types of industrial, technical, commercial and consumer applications.

Cube, Block, & Bar Neodymium Magnets in Premium Grades & Sizes

We stock basic geometric shapes in various thicknesses and premium grades, ranging from N30 to N52. Finishing options include uncoated or with a triple-coated (Ni-Cu-Ni) shiny nickel finish for optimal protection against corrosion. Not all of our inventory is shown on this website. Let us know If you don't see the magnet you're looking for and we'll help you find the optimal solution for your project.

* $15.00 total minimum order (excluding shipping & tax if applicable) - Items can be combined to reach the minimum amount.

*Note: The approximate pull info listed is for reference only. These values are calculated assuming the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

Neodymium Bar, Block & Cube Magnet Features & Characteristics

High Pull Strength & Resistance to Demagnetization

Rare earth neodymium magnets are incredibly powerful for their compact size, with an approximate pull strength of up to 300 lbs. In addition, they are highly resistant to demagnetization, minimizing the need for replacement which can potentially lead to lower overall costs. Their high magnetic strength, resistance to demagnetization, low cost and versatility are ideal for a wide range of technical, industrial, commercial & consumer applications.

Technical Information for NdFeB Bar, Block & Cube Magnets

Manufacturing Methods & Finishes

Our neodymium discs bar, block & cube magnets are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings.

Standard Dimensional Tolerances

Here are the standard tolerances for Rare Earth Magnets (SmCo & NdFeB) based on the following dimensions:

  • +/- 0.004” on length & width dimensions ranging from 0.040” to 1.000”.
  • +/- 0.008” on length & width dimensions ranging from 1.001” to 2.000”.
  • +/- 0.012” on length & width dimensions ranging from 2.001” to 3.000”.

*Tolerance on thickness is +/-0.004” regardless of size.
