The differences between neodymium and ceramic magnets

If you are looking for the best magnet suppliers, it may be wise to visit China. Neodymium magnets China suppliers are known for producing high-quality products that can be applied in a wide range of areas. This post looks into the important details about neodymium magnets, including the differences between neodymium and ceramic magnets. 

The history of neodymium magnets

Neodymium magnets are not a recent invention. They were invented in the early 1980s. The first manufacturers of neodymium metals were General Motors and Sumitomo special metal manufacturers. These two companies discovered that combining neodymium, a rare-earth metal found on the periodic table, and small quantities of iron and boron produced a powerful magnet. The companies introduced neodymium metals as a cost-effective alternative to conventional rare-earth metals. The low price of neodymium magnets is perhaps one of their best features. This causes a lot of comparison between neodymium and ceramic magnets.

The difference between neodymium and ceramic magnets

As mentioned above, neodymium and ceramic magnets are often compared. However, there are numerous differences between these two types of magnets. Below are some of these differences;

a. Cost

Neodymium and ceramic magnets are often compared because they are both quite cost-effective. However, it is worth mentioning that ceramic magnets are naturally cheaper than neodymium magnets. This is the primary reason why these magnets are a popular choice for various consumer applications. Regardless, neodymium magnets are not too expensive.

b. Applications

As mentioned before, ceramic magnets are commonly used for consumer applications. This is because of their low prices. However, neodymium magnets are unmatched when it comes to commercial applications. Their commercial applications can be attributed to the fact that the magnets are typically very strong. They can create a magnetic field of up to 1.4 teslas. This makes them strong enough to handle commercial applications.

c. Strength

Neodymium magnets are typically stronger than ceramic magnets. Ceramic magnets feature a strength of 0.5 teslas, while neodymium magnets feature 1.4 teslas worth of strength. When it comes to physical strength, neodymium magnets are also stronger than ceramic magnets. Neodymium magnets are usually harder. This makes them harder to break and suitable for commercial applications.

On the other hand, ceramic magnets are typically more brittle. This element makes them more susceptible to damage. This is why something as simple as dropping a ceramic magnet on the ground can cause it to break.

d. Durability

Neodymium magnets are naturally more durable because of their physical hardness. However, when it comes to corrosion resistance, ceramic magnets take the lead. Ceramic magnets do not develop rust and corrosion when they are exposed to humidity. On the other hand, neodymium magnets are highly prone to corrosion. For this reason, neodymium magnet manufacturers coat and plate the magnets to increase their corrosion resistance and overall durability.

Conclusion

Even though neodymium is a rare-earth metal, neodymium magnets are not considered rare-earth magnets. This is because they are not made entirely from neodymium. These magnets feature a wide range of metals combined with neodymium.
