Difference between neodymium magnets and ordinary magnets

Differences in magnetic properties. NdFeB magnets have a higher magnetic energy product and coercivity, which means they are able to produce higher magnetic field strengths and are more resistant to demagnetization. In contrast, ordinary magnets have lower magnetic properties.

Stability difference. NdFeB magnets show better stability in high temperature, humidity and other environments, and are not easy to oxidize or corrode, while the performance of ordinary magnets in these conditions will decline rapidly.

Applicable range difference. Due to their high magnetic properties and stability, NdFeB magnets are widely used in fields that require strong magnetic force, such as electric motors, hard disk drives, and medical imaging equipment. In contrast, ordinary magnets are typically used to attract lightweight items or low-precision electronic devices.

Price Differences. Neodymium-iron-boron magnets are more costly, mainly due to their rare-earth metal composition and higher manufacturing difficulty. Ordinary magnets are relatively low cost.

Processing Difficulty Differences. NdFeB magnets may exhibit brittleness during processing and require special attention to processing safety. In contrast, ordinary magnets are simpler and safer to process.

Hardness Difference. NdFeB magnets are harder than regular magnets, which makes them more durable and less fragile during use.

High temperature resistance difference. NdFeB magnets have better high temperature resistance than ordinary magnets and can work at higher temperatures.

To summarize, compared with ordinary magnets, neodymium magnets have stronger magnetic force and longer service life, and are applicable to a wider range of fields. According to the specific application and demand, choose different kinds of magnets for application.
