Is it better to use neodymium iron boron or ferrite?

What is neodymium iron boron? What is ferrite? Do you have no idea that there are still these two types of magnets?
1. Performance
Ferrite: Ferrite has good temperature resistance and stability, compared to ordinary iron boron with a temperature resistance of only 80 degrees. And the price is also cheap
Neodymium iron boron; Iron boron has the characteristics of small volume, light weight, and strong magnetism, and its magnetism is completely different from that of ferrite.
2. Appearance
Ferrite: The ferrite material is loose and has no metallic luster, generally not electroplated, and is usually black
Neodymium iron boron: Most iron boron alloys need to be electroplated, otherwise they can easily rust. The surface has a silver white metallic luster.
3. Price
Ferrite: Ferrite is cheap, many of which are calculated on a per piece basis, and its price is influenced by the shape, size, and processing difficulty of the ferrite
Neodymium iron boron: Nowadays, the price of Zhitie varies almost every day, depending on the brand and special requirements you need to use.
4. Magnetic force
Ferrite: According to research data, the magnetic force of ferrite is usually 800-1000 Gauss, with a density of 5 (g/cm3)
Neodymium iron boron: In a bare magnetic state, the magnetic force of iron boron can reach around 3500 Gauss. Density of 7.5 (g/cm3)
5. Advantages and disadvantages
Advantages of ferrite: The advantages of ferrite are high magnetic permeability, low price, strong temperature resistance, and suitability for low-frequency applications
Defect of ferrite: poor magnetic force.
Advantages of neodymium iron boron: strong magnetic force, high cost-effectiveness, wide range of applications, and good mechanical properties.
Disadvantages of neodymium iron boron: poor temperature characteristics and fragility
