Magnet must see: Ndfeb or ferrite in the end which is more cost-effective?

When it comes to buying magnets, many engineer friends encounter such a trouble: Neodymium iron boron has good performance, but the price is really a bit high. Ferrite is indeed cheap, but I‘m afraid its performance won‘t be sufficient. Today, let‘s have a good talk about how to choose between these two types of magnets.

Let‘s talk about their differences first. Neodymium iron boron is like the "tall, rich and handsome" in magnets, with an extremely strong magnetic force. For magnets of the same size, the suction force of neodymium iron boron can be several times stronger than that of ferrite. However, the drawbacks are also quite obvious. Not only is it expensive, but it is also particularly delicate. When the temperature is high, it is prone to "demagnetization" and requires additional anti-rust treatment.

Ferrite is like an "economical and practical man". The price is only about one-tenth of that of neodymium iron boron, and it is particularly heat-resistant and does not require anti-rust treatment. However, its magnetic force is indeed a bit weaker. Sometimes a larger volume is needed to achieve the same effect.

If it is for high-end audio equipment or precision instruments that have strict space requirements, neodymium iron boron is definitely the choice. Although it‘s a bit more expensive, its performance is truly top-notch.

If it is for ordinary household appliances, toys and other cost-sensitive products, ferrite is sufficient. After all, the money saved is all real money!

Special attention should be paid to the working environment. If it is used in a high-temperature environment, such as near a car engine, ferrite is actually more reliable. Although neodymium iron boron has good performance, it is prone to malfunction at high temperatures.

To be honest, there is no absolute good or bad when choosing magnets. The key is to make them suitable for your specific needs. Just like buying clothes, it‘s not the case that the more expensive, the better. A good fit is the most important. If you are not sure, you might as well tell the supplier the specific usage situation and let them recommend the most suitable solution for you.

Remember, a good choice is not about choosing the most expensive one, but the most suitable one. I hope this article can help you save some money and worry!
