EnglishNeodymium magnets, also known as NdFeB magnets, are made through a process called powder metallurgy. Here are the steps involved in making neodymium magnets:
1.Raw materials: The raw materials used to make neodymium magnets are neodymium, iron, and boron. These materials are combined in the right proportions to form a powder mixture.
2.Melting: The powder mixture is melted in a furnace to form a molten alloy.
3.Milling: The molten alloy is cooled and then milled into a fine powder.
4.Pressing: The powder is then pressed into the desired shape using a die.
5.Sintering: The pressed powder is heated in a furnace at high temperatures to form a solid material. This process is called sintering.
6.Machining: The sintered material is then machined to the final shape and size of the magnet.
7.Coating: The magnet is coated with a protective layer to prevent corrosion and damage.
8.Magnetizing: The magnet is then magnetized using a strong magnetic field.
The neodymium magnet is now ready for use. It is a very strong magnet and has a wide range of applications in industries such as electronics, automotive, and medical devices.
