How To Choose The Right Magnet

How to choose the right magnet

There are many types of magnets, and each type of magnet has a different grade, so how to choose the right magnet?

Before choosing a magnet, we first need to understand the magnet briefly. Magnets are divided into ferrite permanent magnets, neodymium iron boron rare earth permanent magnets, rubber magnets, samarium cobalt magnets, and alnico magnets.

Different types of magnets have different advantages and disadvantages, so we must understand the advantages and disadvantages of each magnet to choose a correct magnet.

Let's make the following comparisons to help you choose magnets.

1. We compare from the price of magnets

SmCo Magnet>AlNiCo Magnet>NdFeB Neodymium Magnet>Ferrite Magent>Rubber Magnet

2. We compare from the magnetic field strength of the magnet

NdFeB Neodymium Magnet>SmCo Magnet>AlNiCo Magnet>Ferrite Magent>Rubber Magnet

3. We compare the difficulty of processing from the appearance and shape

Ferrite Magent>NdFeB Neodymium Magnet>SmCo Magnet>AlNiCo Magnet>Rubber Magnet

4. Let's compare their working temperature (only compare the highest working temperature of each type)

AlNiCo Magnet: 850°C

SmCo Magnet: 750°C

Ferrite Magent: 450°C

NdFeB Neodymium Magnet: 80-220℃

Rubber Magnet: 100°C

5. Comparison of corrosion resistance

Ferrite Magent>Rubber Magnet>AlNiCo Magnet>SmCo Magnet>NdFeB Neodymium Magnet

Through the above comparison, we can clearly understand the advantages and disadvantages of each magnet, so that we can choose a suitable magnet according to the use environment, magnet shape, and magnet strength requirements.

To sum up, neodymium magnets are the strongest magnets, and the price is moderate, it is the most cost-effective type of magnet. However, its development is limited due to its working temperature limitation and its susceptibility to corrosion. At present, we can only improve its corrosion resistance by using more advanced coating technology.
