N35 vs N50 Magnets

N35 vs N50 Magnets

Today, we will compare two popular neodymium magnets – N35 and N50 magnets. Both magnets are also called rare earth magnets. This article will help you know what they are individually, their unique features, and what makes them different. Let’s delve in.

What is N35 Magnet?

Classified as sintered or bonded, N35 permanent magnets represent the first grade in the long list of neodymium magnets.

What is N50 Magnets?

N50 magnets, or grade N50 magnets, are strong permanent magnets. They come with a high level of power.

Comparing N35 Magnets to N45 Magnets

· Comparing Composition

N50 magnets are composed of iron, neodymium, and boron, while N35 magnets are made of cobalt, neodymium, and boron.

· Comparing Coercive Force

N50 magnets come with 836 KOe coercive force, while N35 magnets stand at 868 KOe. This means that N35 magnets have a coercive force that is very high and higher than that of N50 magnets.

· Comparison of Intrinsic Coercive Force

Both magnets come with 955 KOe, which means they have the same intrinsic coercive force.

· Comparison of the Maximum Operating Temperature

The maximum operating temperature has to do with the highest temperature under which the magnet can still work perfectly. Both magnets come with a maximum operating temperature of 80°C.

· Comparing Remanence

Remanence is referred to as residual magnetism or induction. This refers to a magnet’s strength even after external magnetic fields are taken away. For N35 magnets, it is from 11.70 to 12.20 mT, while N50 magnets have a range from 13.90 to 14.40 mT. This means N50 is higher here than N35 is.

· Comparing the Maximum Energy Product

N50 magnets come with an MGOe of 376 to 408 kJ/m3, while N35 magnets have a range of 263 to 286 kl/m3.

· Comparing Sizes and Shapes

N50 magnets come in unique sizes and shapes like discs, cylinders, rounds, rings, rods, tubes, spheres, arcs, wedges, segment countersunk, cubes, ring countersunk, and flat bars.

On the other hand, N35 magnets include cylinders, cubes, rods, blocks, assemblies, bars, spheres, discs, rings, buttons, and rods.

· Comparing Coatings used

There is a need for neodymium magnets to have coatings. These coatings help to keep the magnets safe, durable, and free from corrosion, enhance their look, and also make using them very easy.

Some coatings for N50 magnets include nickel, zinc, epoxy-nickel, rubber, epoxy, Teflon, etc. N35 magnet coatings include epoxy, zinc, Teflon, nickel, black epoxy, copper, gold, plastic, titanium nitrate, etc.

· Comparison of Magnetic Strength

N50 magnets come with 14,200 gauss, while N35 magnets have 12,500 gauss. This means that N50 has superior magnetic strength to N35.

· Comparing Weight

N50 is heavier compared to the N35 magnet.

· Comparing Durability

N50 magnets have higher durability rates than N35 magnets.

· Comparing Versatility

Both magnets can be used in different industries and for different applications. This makes them versatile in meeting different needs.

· Comparing Major Applications
