We provide different types of magnetic materials, for example, hard and soft magnets, bonded magnetic compounds, ferromagnetic compounds to meet the diverse application requirements for our customers, including hard magnetic bonded compounds and soft magnetic bonded 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.
High-density plastic has a density of up to 13g/cm3 by adding high gravity compounds to the plastic matrix, which is higher than that of ordinary metal. It can be used as a shielding enclosure for high-energy rays, counterweight material, substitute material for lead, etc.
Properties of Soft Magnetic Bonded Compounds
Less production process and suitable for automatic production
The product is energy-efficient and harmless to the environment
Applications of Soft Magnetic Bonded Compounds
Counterweight material (counterweight of automobile, imitation gun, golf equipment, etc.); Medical industry.
