We provide types of magnetic materials and their properties, for example, bonded magnetic compounds to meet the diverse application requirements for our customers, material of permanent magnet has include soft magnet and hard magnet bonded compounds and ferromagnetic compounds. If you are looking for a lightweight, reliable, mass-produced, and customized product, bonded magnetic compounds are an ideal alternative.In addition to bonded magnetic compounds, we can also cooperate with customers to develop customized functional composite materials, such as high-density compounds and metal bonded plastic. We are committed to providing customers with new user experience and different design inspiration.
Bonded Neodymium Magnetic Compounds Introductions
Bonded neodymium magnets (bonded NdFeB magnet) have high mechanical performance and no need for surface coating and other processes, which can effectively avoid the shortcomings of brittle and poor corrosion resistance of sintered NdFeB magnet.
Isotropic bonded magnet with complex shapes can be obtained through injection molding and subsequent magnetization process, there is no need to apply the magnetic field into an injection mold. Yet, it is necessary for anisotropic bonding neodymium magnets to apply the magnetic field into injection mold to magnetize magnets in a variety of patterns.
A bonded neodymium magnet can be magnetized in the axial, radial, multi-poles, or local direction, which is difficult for bonded NdFeB magnet.
Bonded NdFeB Magnet Material Properties
Several times stronger magnetic property than ferrite bonded magnet contributes to miniaturization and lightweight of parts.
High dimensional precision makes it suitable for precision parts.
The bonded neodymium/NdFeB magnet material can be wholly, partially magnetized, or demagnetized.
We will offer the neodymium iron boron magnet properties and ndfeb material properties as will as ndfeb magnet density to you.
Applications of Bonded Neodymium Magnetic Compounds
Motor rotor; micro-sensor; micro-motor; electronic expansion valve; etc.
