Neodymium Block Magnets

Neodymium Blocks and Cubes

Rare Earth magnets have become the most popular type of permanent magnet for the vast majority of applications. Since their development in the 1980s, they have steadily become more popular due to their incredible magnetic strength.

Neodymium magnets have led to incredible advancements in many forms of technology as they produce enhanced power in a smaller form. Before their formulation, magnets were mostly available in Ferrite, Alnico, and Samarium Cobalt. These magnets are still commonly used due to their superior heat resistance. However, they require far more magnetic material to achieve a similar hold to a Neodymium magnet.

Uses for block magnets. 

Magnetic blocks are utilised in all sorts of electronic devices. Our range includes micro magnetic cubes—these tiny square magnets are utilised in aeronautical, automotive, mining and aviation equipment and machinery.

With their broad magnetic surface, long bar magnets are appropriate for holding applications such as magnetic tool holders. Neodymium magnets, on the other hand, are brittle and require careful handling. For this reason, it is often more practical to use a series of smaller magnets rather than one large magnet.

Neodymium block magnets are widely used in arts and crafts, including textiles, leather crafts, and wooden sculptures. We've also supplied thousands of block magnets to the Movie World theme park on the Gold Coast in Queensland, for use in costumes and movie props. Easily concealed, magnets provide the perfect solution to many staging and set dilemmas.

Characteristics of block magnets

All types of permanent magnets have their own beneficial characteristics and likewise their obstacles. Ferrite magnets are weaker than Neodymium magnets, but they provide excellent resistance to high temperatures. Alnico magnets have a stable magnetic field and excellent resistance to corrosion.

Rare Earth block magnets are indeed the world’s strongest permanent magnets—however, they do not perform well in high operating temperatures. Neodymium magnets have a maximum operating temperature of 80 degrees Celsius—it is recommended not to exceed this. Magnets subjected to temperatures above this will decline in magnetic strength and may sustain permanent damage. We do stock some Neodymium block magnets that have been developed to withstand higher temperatures. These are indicated by the grade listed on the product page.

Frenergy is also experienced in manufacturing custom magnets. We work with the best factories to produce custom magnets for our customers. These can be made in any size, grade, coating, or with higher temperature compatibility. Contact us via email with your custom magnet requirements. Minimum orders may apply.

We know that price is an important component of our customers' purchasing decisions in addition to quality. We offer competitive bulk discounts, if you have any questions or want to confirm pricing, please don’t hesitate to contact our team. We endeavour to put as much information as possible on each product page to assist our customers. However, if you have any questions or would like assistance choosing the best magnet for your job, please contact us.


How can I use magnetic blocks?

Neodymium block magnets come in a wide variety of sizes. They can be used as a singular magnet or in a row to create a wide holding surface; as seen in magnetic tool holders. Mini magnets are popular with many customers who wish for a hidden or discrete holding system. Large and powerful block magnets need to be handled with care. They are brittle and can break easily when allowed to snap magnetically to another hard surface.

The Pull Force listed for each magnet is based on lifting 10mm thick steel vertically. Magnets on a vertical surface (of 10mm thick steel)  are generally able to hold around 30% of the pull force listed due to the effects of gravity and the lack of traction between the surface and the shiny magnet.
