The properties of permanent magnets and magnetic powder generally, include a rare-earth metal, as well as Iron (Fe) and Boron (B). More commonly used rare-earth metal is Neodymium (Nd). These materials are derived from the strong magnetocrystalline anisotropy and high saturation magnetization of the compound E2Fe14B1.
Newland powders areeasily ready for making bonded permanent magnets. We make our powders using a process known as “Jet Casting”. It involves melting an ingot of NdFeB, and then shooting the metalunder high pressure onto the surface of a rotating metal wheel that is kept at cool temperatures while the molten metal is cooled.
The material solidifies into a small metal ribbon that is about 35 µm (micrometers) thick and 13 mm wide. By controlling variables such as the flow rate of the metal, the wheels rotating speed, the cooling rate; we can achieve optimum magnetic properties.
The product range of our magnets covers three kinds of magnetic powder, and all kind of bonded magnets. They can be used in the automobile industry, office automation, electric toys and magnetic curing products,etc. because they have high quality and high strength and they can be made into complicated shapes.
The types of magnetic powders we can offer are:
– Bonded neodymium magnetic powder
– Neodymium powder with adhesive
– Magnetic Plastic Particles
Bonded neodymium magnetic powder is a kind of powder material commonly used in the preparation of magnetic materials, and its main components include neodymium-iron-boron (NdFeB) magnetic powder and binder. Bonded Nd magnetic powder is usually made of fine NdFeB magnetic powder particles mixed with binder and processed through molding, pressing and sintering. The bonded NdFeB magnetic powder is characterized by strong magnetic properties, strong bonding and good molding properties, and is widely used in the preparation of various magnetic parts.
