20mm neodymium magnets have a magnetic field approximately 10 times stronger than conventional magnets and are used in a variety of industries, including automotive, aerospace, manufacturing, and electronics. They are used in Magnetic toys, MRI machines, and even headphones and speakers. One of the main advantages of neodymium magnets is their compact, lightweight design, which allows them to deliver powerful magnetic fields in a small size. This makes them ideal for electronic devices and products where size and weight are important factors.

One of the main parameters of Magnetic lacquer 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 1.3 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 841 and 1109 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.

11.Are there any restrictions on the production or use of 20mm neodymium magnets?

Yes, there are restrictions on the production and use of neodymium magnets. Neodymium magnets are subject to the European Union's Restriction of Hazardous Substances (RoHS) directive, which restricts the use of certain hazardous materials in electrical and electronic equipment. Additionally, neodymium magnets are subject to the International Maritime Organization's (IMO) International Maritime Dangerous Goods (IMDG) Code, which regulates the transport of hazardous materials by sea. Finally, neodymium magnets are subject to the United Nations' International Atomic Energy Agency (IAEA) regulations, which regulate the use of radioactive materials.

12.About the development history of 20mm neodymium magnets factory

Neodymium magnets were first developed in the early 1980s by General Motors and Sumitomo Special Metals. The magnets were made from an alloy of neodymium, iron, and boron. This alloy was found to be much stronger than traditional ferrite magnets, and could be used to create much smaller and more powerful magnets. Since then, neodymium magnets have become increasingly popular and are now used in a wide variety of applications, from consumer electronics to industrial machinery. The development of neodymium magnets has also led to the development of specialized factories that produce these magnets. These factories use a variety of processes to create the magnets, including sintering, hot pressing, and injection molding. The magnets are then tested for quality and strength before being shipped to customers.

13.What is the manufacturing process for 20mm neodymium magnets?

Our 20mm neodymium magnets products undergo strict quality control to ensure customer satisfaction. 1. Raw Material Preparation: Neodymium magnets are made from an alloy of neodymium, iron, and boron. The raw materials are melted together in a vacuum induction furnace to create a homogenous alloy. 2. Compacting: The molten alloy is then poured into a die and compacted under high pressure to form a solid block. 3. Sintering: The compacted block is then heated in a vacuum furnace to sinter the material, which increases its strength and magnetic properties. 4. Machining: The sintered block is then machined into the desired shape and size. 5. Magnetizing: The machined magnet is then magnetized by exposing it to a strong magnetic field. This process aligns the magnetic domains within the material, creating a permanent magnet.

14.About 20mm neodymium magnets R&D capabilities

Neodymium magnets are a type of rare earth magnet that is composed of an alloy of neodymium, iron, and boron. They are the strongest type of permanent magnet available and are used in a wide range of applications, from consumer electronics to industrial machinery. Neodymium magnets are highly resistant to demagnetization and have a high coercivity, making them ideal for applications that require a strong magnetic field. Neodymium magnets are typically produced through a process of powder metallurgy, which involves mixing the alloy components together and then pressing them into a mold. The resulting magnets are then heat-treated to increase their coercivity and strength. Research and development of neodymium magnets is ongoing, with new alloys and manufacturing processes being developed to improve the performance of these magnets.
