Key parts for the miniaturization and efficiency of various industrial equipment! Neodymium magnets, which possess overwhelming magnetic strength among permanent magnets.
"Neodymium magnets" are rare earth sintered magnets (anisotropic) primarily composed of iron, neodymium, and boron. After processes such as melting and grinding, the powder is refined to micron-sized particles and then compressed and molded using magnetic field pressing (molding in a magnetic field). This is followed by sintering to produce the magnet base material (in rectangular or cylindrical shapes). Next, the magnet base material is machined into dimensions such as round, square, ring, or tile shapes, and further surface treatment (typically nickel plating) is applied to create the final product. Leveraging their high performance, they are increasingly being used as key components to promote miniaturization and efficiency in devices. [Features] - The maximum energy product (BH) max can exceed 48 MGOe. - Excellent cost performance with no concerns regarding supply. - Materials with enhanced coercivity and heat resistance have been developed. - Nickel electroplating is standard for rust prevention. *Please feel free to contact us for more details.

basic information
【Manufacturing Process】 1. Mix each raw material. 2. Dissolve the mixed raw materials at high temperatures to create an alloy. 3. Turn the alloy into a fine powder. 4. When pressing the fine powder, apply a magnetic field to align the magnetization direction and create molded powder products. 5. After sintering at approximately 1100°C, perform heat treatment at around 600°C to enhance magnetic properties. 6. Process the manufactured magnetic base material to finish it into the product shape. 7. Perform surface treatment for rust prevention. 8. Apply a magnetic field to create a magnet with magnetic force. *For more details, please feel free to contact us.
