Company
LingDa was established in 1998, which is the leading manufacturer of the high quality Sr.Ferrite magnet in southwest of China, located at TongLiang industrial district, ChongQing, China.
LingDa is the expert to design, research and produce any application of segment ceramic magnet. There is 10 years experience to produce the different dimensions and the different styles magnet for motor using in automobile, motorcycle, and other Industrial motor. LingDa produces the top grade arc Sr. ferrite permanent magnet over 5000 tons and the turn over is 25 million USD per year. We have the advanced producing equipment and exact measure instrument to keep the quality and performance of the products steady. With the technology support from China magnet institute, Denso and the technology university, we trust the magnet would be better with our innovation. Main market of us is in ChongQing and other regions of China for 10 years, and we are bringing the Lingda magnet into the world and drive the motor better all.
LingDa had passed the international quality assurance of ISO/TS16949 in 2005, ISO9001:2000 and QS9000. Supply to 32 domectic electric-motor manufacture customers and Japan Denso Corporation of China,Brazil and India, we believe that our magnet are the best choice fo your motor application and Lingda is worthy for your depending.
Upon the advanced technology, the upstanding producing management and Ecology-minded, we have been decreasing cost of us, including the labor cost, source cost and producing cost. With these effective acting, lingda has been being successful in domestic arc magnet market and abroad. For the future business, we will pay more attention on the technology innovation, energy saving and environmental awareness.
Jointing venture with the second largest magnet material company, let us own the self material company known as Kunming Hualing Gaoheng Magnetic Co., Ltd. and BGRIMM Magnetic Material & Technology Co., Ltd., to make the material cost lower. And established plant in Chongqing, which is the southwest China machine manufacture district, the labor cost of us is far less.

Ferrite magnet sometimes called as ceramics are electrically non-conductive magnets which is manufactured since 1954. It consists of iron oxides such as Hematite (Fe2O3) or Magnetite (Fe3O4) with traits of other metal (strontium) oxides. Though with respect to other magnets they provide less energy they are very stable and high resistance to demagnetization. They have high permeability and in saturated state they conduct a magnetic flux which allows them to store stronger magnetic fields than iron.
Properties
- The strontium ferrite ceramic magnets are resistant to demagnetization.
- These sintered permanent magnets are categorized into two parts on the basis of the applications- electromagnets and permanent magnets.
- These sintered permanent magnets show less coercive force.
- The ferrite ceramic magnets are brittle and are prone to breakage and rupture. Due to their brittle nature they cannot be drilled or machined.
- strontium ferrite with well resistant to corrosion.
- strontium ferrite with very good temperature stability ( high working temperature).
Lingda ferrite magnets have following applications:
- Electronic inductors
- Transformers
- In radar as absorbing particles
- Industrial automation
- Conveyor belts
- Electric motors for all solution in auto industry, home application and other DC/AC motors.
- Magnetic separators
- Magnetic resonance imaging
Lingda ferrite magnets are manufactured by using one process:
Through wet process, anisotropic strontium ferrite magnets can be produced. Anisotropic ferrite magnets can be magnetized in the direction of orientation as they are all oriented in the manufacturing direction.
