Available in various sizes including square magnets and bar magnets from our online store. Our Block magnets also come in a variety of magnetic grades, from N35 through to the strongest grade, N52. Take a look through our huge range today.
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 the incredible magnetic strength they provide.
Neodymium magnets have led to incredible advancements in many forms of technology as they produce enhanced power in a smaller form. Prior to their formulation, Ferrite, Alnico and Samarium Cobalt were the available types of magnets. These magnets are still commonly used due to their attributes such as 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 and these tiny square magnets are utilised in aeronautical, automotive, mining and aviation machines. Long bar magnets are appropriate for use in holding applications such as magnetic tool holders as they provide a broad magnetic surface. Neodymium magnets 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.
Rare Earth magnets are widely used in arts and crafts, like textiles, leather crafts and wooden sculptures. We've also supplied thousands of block magnets to Movie World, to be used 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 however they provide excellent resistance to high temperatures. Alnico magnets have a stable magnetic field and these magnets have excellent resistance to corrosion.
Rare Earth block magnets are indeed the strongest permanent magnet however they do not perform well in high operating temperatures. Neodymium magnets have a maximum 80 degrees Celsius operating temperature recommended. Magnets subjected to temperatures above this will decline in magnetic strength and may sustain permanent damage. We do have 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 very 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, any grade, any coating, or with higher temperature compatibility. Contact us via email with your custom magnet requirements. Minimum orders may apply.
We know that in addition to quality, price is an important component of the purchasing decision for all of our customers. We offer competitive bulk discounts, if you have any questions or would like to confirm pricing please don’t hesitate to contact our team. We endeavour to put as much information as we can 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 can be seen in magnetic tool holders. Mini magnets are popular with many customers that 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.
