1. Mixing:
A magnetic material is mixed with a binder to create a slurry or a molten mixture.
2. Pressing:
The slurry or molten mixture is pressed into a mold to form the desired shape.
3. Heating:
The mold is heated to cure the binder and harden the magnet.
4. Cooling:
The mold is cooled, and the button magnet is removed.
5. Finishing:
The button magnet may undergo additional finishing processes, such as polishing or coating, to improve its surface finish or protect it from corrosion.
There are many grades of neodymium button magnets available, and the appropriate grade will depend on the specific application. The most common grades for neodymium button magnets are:
N35: :
This is a medium-strength grade, with a maximum energy product (BHmax) of 35 MGOe (Mega Gauss Oersteds). N35 magnets are commonly used in consumer products and industrial applications.
N38:
This is a higher-strength grade, with a BHmax of 38 MGOe. N38 magnets are often used in applications where a stronger magnetic force is required.
N52:
This is the highest-strength grade commonly available in button magnets, with a BHmax of 53 MGOe. N52 magnets are used in applications where the highest possible magnetic force is required.
Other grades, such as N42, N45, N48, N50, N55, also be available. The specific grade of a button magnet will depend on the material and manufacturing process used to produce it.
