We are Committed to Pioneering Magnetic Technologies

Quadrant takes the lead in the industry and delivers cutting-edge magnetic technologies that boost the world’s development. It is our mission to ensure our customer’s requirements are met each and every time. 

With a 20+ year foundation in magnetic solutions, Quadrant is a vital force in applied industrial technology. We are deeply rooted in the development of magnetic materials, and have also taken the initiative to elevate our technological level by absorbing innovation challenges, advanced manufacturing, and capabilities for magnetizing, testing, and assembling. We are now enthusiastically moving towards developing enhanced comprehensive magnetic technologies.

Your Pipeline to Innovative Products and Services

Through technology transfer, we have partnered with customers to cut time and allocate resources in the R&D process, bringing new products and services to market with speed and efficiency.

Technological Advancements

Sintered NdFeB

Grain Boundary Diffusion (GBD)

Chemical optimization and process enhancements have  allowed Quadrant to achieve higher coercivity (HcJ) without reduction of remanence (Br). Quadrant developed a Rotary GBD technique that has enabled greater progress in this quest, while keeping the efficient HRE usage of Dy/Tb for cost benefit. It is a significant enhancement for small piece parts of Nd-Fe-B magnets.

AI & Automation

Quadrant’s machine learning systems use modeling with iterative process control and measurement-data analysis to guide our lean manufacturing. Automated manipulators and conveyors move product through assembly, magnetization, and packaging operations with fool-proofing fixtures and processes. CCD, laser optical inspection tools work with our inline magnetic inspection systems to provide large quantities of quality products.

Soft Magnetic Materials

Amorphous, Nanocrystalline Alloys

The never-ending advancement of sophisticated electronic products requires the continuous development of increasingly complex materials. Quadrant develops in mass production of customizable, ultra-thin, nanocrystalline strip materials. These polycrystalline materials exhibit Js>1.7T even with the extremely low Hc of 1A/m.

Sintered NdFeB

Coating / Plating

Quadrant’s various coatings lines offer solutions such as electro, electroless and vacuum platings, as well as thermal sprays and chemical treatment. We supply parts with thin or thick coatings with materials from Platinum & Parylene to Nickel & Epoxy. These surface treatments improve wear and corrosion resistance of vulnerable metals as well as enhancing the appearance. 

Quadrant is committed to the sustainability and environmental coating solutions, we enjoy opportunities to develop innovative coatings that passed the Environmental Protection Policy. 

Haptic Motors

Haptic Technology

Haptic uses a vibrating component which is driven by an electronic circuit. Quadrant’s motor portfolio includes Coin (“Pancake”) Vibration Motors, Linear Resonant Actuator (LRA) Motors (Z-axis), ERM Cylinder Motors, and Sonic Motors. We are emerging haptic technologies to simulate improved tactile sensations and make the interaction more precise.  


Drone Technology

Quadrant has been working with many Drone motor applications for craft both in the air and under water. We design and manufacture brushless motors and components to meet customer requirements for greater torque, speed, and energy efficiency.

Material & Manufacturing

Efficiency in Material Fabrication

It is our mission to increase efficiency and reduce cost in fabrication equipment and operations. Material wire saw cutting is an integral process for most of our products, we slice magnet size down to a 25μm thickness with optimized wire saw equipment and processes. Quadrant continuously improves our state of the art ID cutting, WEDM, laser, waterjet and other cutting processes.

Clean Energy

Solar Solutions

Quadrant launched our clean energy program in 2017. Since then, we have installed 130,000 square meters of solar arrays and systems across the rooftops of our Hangzhou, Changde facilities. While some facilities have already achieved 100 percent energy efficiency, our aim is to have a global zero-carbon footprint.

Rare Earth Recycling

In addition to our clean energy programs, Quadrant leads in magnetic material recycling in China. Rare earth elements are required materials in many consumer products, and we currently have established programs for recycling rare-earth-containing magnets and magnet-processing scrap.

Quadrant helps our suppliers with rare earth material conservation by setting up recycling processes, and  transition towards the energy efficiency.

Cobalt free & Cobalt Recycling

Cobalt is one of the most frequently used metals for both magnetic and physical strength. While not scarce in the earth’s crust, geopolitical actions along with rapidly increasing demand have caused rising prices and metal shortages. Quadrant continues our extensive work on metal injection molded (MIM) to reduce the cost of fabricating components from Cobalt Chromium, Iron Cobalt, and other Co-containing alloys. We require green Cobalt suppliers for some products and continually push for it in more. Our requirements of key suppliers have led to advancements in Cobalt recycling both in material integrity and in market demand.
