Advanced Technology & Materials Co., Ltd. (AT&M), also known as Antai Technology, is proud to announce its participation in CWIEME Berlin 2026, the world's leading exhibition for coil winding, electric motor, and transformer manufacturing. Under the theme "Where Power Meets Progress," this premier industry event takes place from May 19–21, 2026 at the Messe Berlin in Germany. AT&M's Functional Materials Division will be showcasing its comprehensive range of advanced magnetic materials and magnetoelectric solutions at Booth 32B34 in the Magnets & Magnetic Materials category.
As a significant enterprise in China's magnetic materials sector, AT&M brings decades of research, development, and production expertise to the global stage. The company's product portfolio spans sintered NdFeB permanent magnets, bonded NdFeB magnets, amorphous and nanocrystalline materials, and customized magnetic components, serving industries from automotive electrification to industrial automation.
Sintered NdFeB Magnets for High-Performance Applications
AT&M's sintered NdFeB permanent magnets are engineered for demanding applications requiring high magnetic energy product and excellent magnetic properties. The following table outlines the key performance parameters across available grades:
| Grade Series | Remanence Br (T) | Coercivity Hcj (kA/m) | (BH)max (kJ/m³) | Max Operating Temp (°C) | Target Applications |
|---|---|---|---|---|---|
| N Series (N35–N52) | 1.18–1.48 | ≥ 876 | 263–422 | 80 | Consumer electronics, speakers, sensors |
| H Series (N38H–N48H) | 1.26–1.42 | ≥ 1353 | 287–390 | 120 | Industrial motors, servo drives |
| SH Series (N35SH–N45SH) | 1.18–1.37 | ≥ 1592 | 263–366 | 150 | EV traction motors, generators |
| UH Series (N35UH–N40UH) | 1.18–1.32 | ≥ 1990 | 263–326 | 180 | High-temperature motors, wind turbines |
| EH Series (N35EH–N38EH) | 1.18–1.28 | ≥ 2387 | 263–310 | 200 | Aerospace, high-power density systems |
AT&M's sintered NdFeB magnets deliver the magnetic performance required for the latest generation of high-efficiency electric machines, including electric vehicle traction motors, industrial servo systems, and direct-drive generators for renewable energy.
Bonded NdFeB Magnets for Complex Geometries
In addition to sintered magnets, AT&M manufactures bonded NdFeB magnets using compression and injection molding processes. These magnets offer unique advantages for applications where complex shapes, tight tolerances, and multi-pole magnetization are required:
| Process Type | Remanence Br (T) | Max Operating Temp (°C) | Dimensional Tolerance | Typical Applications | Production Volume |
|---|---|---|---|---|---|
| Compression Bonded | 0.65–0.85 | 150 | IT7–IT9 | Sensors, automotive actuators, stepper motors | 10k–1M units |
| Injection Bonded | 0.50–0.70 | 120 | IT6–IT8 | Small motors, encoders, pump impellers | 100k–10M units |
Bonded NdFeB magnets provide excellent corrosion resistance without additional coating, as the polymer matrix encapsulates the magnetic powder particles. This makes them particularly suitable for applications in humid or chemically aggressive environments.
Amorphous and Nanocrystalline Materials
AT&M is also a leading producer of amorphous and nanocrystalline soft magnetic materials, which are critical components in modern power electronics and transformer applications:
| Material Type | Saturation Induction Bs (T) | Permeability µ (×10³) | Core Loss (W/kg @ 20kHz, 0.2T) | Strip Thickness (µm) | Key Applications |
|---|---|---|---|---|---|
| Amorphous (Fe-based) | 1.56 | 1–3 | < 3.5 | 22–28 | Distribution transformers, PFC inductors |
| Nanocrystalline (Fe-based) | 1.25 | 20–80 | < 1.5 | 14–22 | Common mode chokes, current transformers, EMI filters |
| Nanocrystalline (Co-based) | 0.75 | 80–150 | < 0.5 | 14–20 | High-frequency transformers, saturable reactors |
These advanced soft magnetic materials offer significant advantages over conventional silicon steel, including drastically reduced core losses at high frequencies, higher permeability, and thinner strip profiles, enabling more compact and energy-efficient transformer and inductor designs.
Magnetoelectric Solutions and Customization Capabilities
AT&M provides end-to-end magnetoelectric solutions, from material selection and design optimization through prototyping and mass production. The company's engineering team works closely with OEMs to develop customized magnetic components that meet specific performance, dimensional, and cost targets.
