What is a N38 Magnet
The N stands for neodymium. Number 38 stands for the strength of the magnet. These alloyed neodymium magnets are used because of their increased resistance to corrosion and oxidation. N38 magnets are typically plated with nickel and copper to increase their resistance.
There are several advantages of using a n38 magnet. The benefits include:
- N38 magnets are highly durable and can be used for up to ten years. They lose their strength by approximately one percent.
- Their magnetic ability is strong and therefore it is not easy to demagnetize them using external sources.
- They are aesthetically pleasing due to their coatings. N38 magnets may feature a gold, silver, or nickel finish giving them a shiny appearance.
- They have an increased ability to magnetize on the surface of the magnet
- Different compositions have increased resistance to high temperatures. They can operate at temperatures of up to 230 degrees.
Estimated N38 Magnet Strength
There are different strengths of n38 depending on the composition of the magnet. Strength of a magnet can be measured in various ways.
- Remanence is the ability of a material to preserve its magnetic ability. N38 has 1220- 1250Br
- Coercive force is the ability of a magnet to resist demagnetization from an external source. It has 889hcb.
- Intrinsic coercive force is the ability of a magnet to resist demagnetization in a closed circuit. N38 has 995hcj.
Composition of N38 Neodymium Magnets
N38 is made up of alloys of iron and nickel fused with neodymium. The alloyed magnet is plated with two layers of nickel at the top and bottom and a layer of copper in the middle.
This process utilizes electrolytic which help boost its resistance against oxidation and corrosion.
Features of N38 Neo Magnet
Features such as coating may differ from one magnet to the next. However, the standard features for n38 are
- They are strong and durable
- Has an increased resistance against corrosion.
- N38 magnet has a high precision attributed to its low tolerance
- N38 has a Remanence of 1220 to 1250Br
- Coercive force of n38 is 889hcb.
- It has an Intrinsic coercive force of 995hcj
- The maximum energy of the product ranges from 227 to 310bh
- Its maximum operating temperature is 80 degrees
How Magnet N35 vs N38 Compare
- N35 is made up of boron and iron alloyed with neodymium whereas n38 is composed of iron and nickel.
- N35 is relatively weaker than N38 magnet.
- N35 has a Remanence 1170 to 1220br while n38 has of 1220 to 1250Br
- Coercive force of n35 868 while that of n38 is 889hcb.
- The Intrinsic coercive force of both n38 and n35 995hcj
- The maximum energy of product for n35 is 263-287 while that of n38 ranges from 227 to 310bh
- N35 and N38 both have a maximum operating temperature of 80 degrees
Comparing N38 vs N52
The alloys of neodymium are numbered according to their strengths starting from N 35 and ending with N52. N35 is the weakest and N52 is the strongest.
- N38 is weaker than N52 which is the strongest alloy in this category.
- N38 has a remanence ranging from 1220 to 1250Br while N52’s remanence ranges from 1430 to 1480br.
- The coercive force of N52 is 786hcb while that of n38 is 889hcb.
- The Intrinsic coercive force of N52 is 876 while that of N38 995hcj.
- The maximum energy of product for N52 ranges from 398 to 422bh while that of N38 ranges from 227 to 310bh.
- N52 and N38, as all the alloys in this category, have a maximum operating temperature of 80 degrees.
Recommended N38 Magnet Price
N38 magnet price ranges from as low as 4 dollars to as high as 2000 dollars. The size, design, and type of finish all factor in the pricing.
For example, for a gold finish nickel, copper, and gold are used. For a copper finish, you need nickel and copper it will therefore be cheaper than the gold coating and plastic coating will be even cheaper.
Adding gold to the raw materials will make the price go higher using some cheaper like rubber will make the price go down. Disks of the same shape that vary in size and thickness also vary in price. The energy cost of producing the piece may also be considered.
