20mm disc neodymium magnets is made from an alloy of neodymium, iron and boron, hence the name NIB magnets. The alloy is then heated and formed into the desired shape and then magnetized. The resulting magnet has high resistance to demagnetization and can maintain its magnetism for a long time. Due to their high strength, neodymium magnets are used in a wide range of applications, including Magnetic resonance therapy. They are also commonly found in everyday items such as headphones, speakers, and even magnetic jewelry clasps.

One of the main parameters of Rust-resistant paint is remanence, which is a measure of the strength of the magnetic field that remains after a magnet has been magnetized. This is also called magnetic flux density and is usually measured in Teslas (T). Neodymium magnets have very high remanence values, typically in the 1.1 to 2 T range, making them ideal for applications requiring strong magnetic fields. Another important parameter is coercivity, which is the material's ability to resist demagnetization. Neodymium magnets have a high coercivity, typically between 812 and 1222 kA/m, which means that once they are magnetized they are difficult to demagnetize. This makes them suitable for use in applications with high operating temperatures or strong magnetic fields. At Honesun, we offer a wide range of neodymium magnets in various sizes, shapes, and grades to meet the diverse needs of our customers. Our neodymium magnets are carefully produced and tested to ensure the highest quality and performance.

12.About 20mm disc neodymium magnets production equipment

Neodymium magnets are a type of rare earth magnet that is made from an alloy of neodymium, iron, and boron. They are the strongest type of permanent magnet available and are used in a variety of applications, including motors, generators, and loudspeakers. The production of neodymium magnets requires specialized equipment, such as a vacuum furnace, a press, and a sintering furnace. The process begins with the mixing of the neodymium, iron, and boron powders in the correct proportions. The mixture is then placed in a vacuum furnace and heated to a high temperature. This causes the powders to melt and form a homogenous alloy. The alloy is then placed in a press and formed into the desired shape. Finally, the formed alloy is placed in a sintering furnace and heated to a high temperature, which causes the alloy to become a permanent magnet.
