Q & A

Why are neodymium magnets so strong?

Neodymium magnets are extraordinarily strong due to their unique material composition. These magnets are made from neodymium (a rare earth element), iron, and boron. NeFeB boasts one of the highest magnetic moments among natural elements. When combined with iron and boron, which also possess strong magnetic properties, it results in a powerful combination. The crystalline atomic structure of neodymium enables the alignment of magnetic moments, enhancing the overall magnetic field. Moreover, n52 neodymium magnets exhibit high coercivity, allowing them to resist demagnetization. The sintering process, which involves compacting and heating the materials, further aligns magnetic domains, resulting in their exceptional strength. This combination of factors creates strong neodymium magnets with a high energy product and unparalleled magnetic potency.In contrast, ferrite magnets are less potent due to their lower magnetic moments and less ordered structures. While other rare-earth materials exhibit strong magnetism, neodymium’s combination of properties, including high coercivity and the sintering process, distinguishes it as the strongest magnet in the market.

 

What are high-strength neodymium magnets used for?

High-strength neodymium magnets find critical applications in both industry and daily life. In industry, they underpin powerful lifting systems for handling heavy materials in settings like scrapyards and metal fabrication. These large heavy duty magnets enable efficient magnetic separation of ferrous materials in mining and recycling. In construction, they’re used for securing formwork and in steel framework assembly. In daily life, these magnets can be found in heavy-duty magnetic door latches and even for hanging heavy objects on magnetic boards. Their remarkable strength and reliability make them indispensable for applications demanding substantial lifting and holding capabilities.

 

Are neodymium heavy duty mounting magnets dangerous?

Powerful neodymium magnets can be dangerous if not handled properly. Their strong magnetic fields can cause injury by pinching or trapping body parts. Swallowing or inhaling small magnets can be life-threatening, as they can attract each other within the body, leading to tissue damage. Those neodymium heavy duty mounting magnets should be kept away from electronic devices, credit cards, and pacemakers, as their magnetic fields can interfere with these devices. While they are generally safe when handled with care, it’s crucial to exercise caution, especially when children are around, and to follow safety guidelines to prevent accidents and potential health hazards.

 

How to store permanent rare earth magnets?

Storing neodymium rare-earth magnets safely and effectively requires precautions due to their powerful magnetic fields. To store large heavy duty magnets safely, use non-magnetic containers like plastic or cardboard to prevent unintended attraction to metallic objects. Keep them away from electronic devices, credit cards, and pacemakers as they can be affected by super strong magnets. Store large neodymium magnets individually, so they don’t attract or collide with each other, which could cause chipping or breaking. Label the containers to know the magnet’s strength. When handling, wear safety goggles and gloves, and be cautious to avoid pinching injuries. Proper storage and handling ensure safety and protect the magnets’ integrity.

* We test the holding force of magnetic assembly by attaching it on a 20mm thick steel plate (low carbon steel with no coating) at room temperature and then pulling it slowly in vertical direction with the device that is sensitive enough to record the strength at the moment when magnetic assembly is separated from the steel plate. This is to give you a reference while the actual holding force in real application could be different with the change of pulling direction, thickness of the steel, surface treatment, etc.
