QD MAGNET’s marine-grade materials withstand salt spray (ASTM B117, 3000hrs) and humidity (95% RH). Featuring alnico alloys with TiN coatings and ferrites with IP68 encapsulation, our solutions power underwater robotics and offshore energy systems. Download ASTM G85 test certificates.
Alnico 5 and 8 grades from QD MAGNET operate from -270°C to +600°C, ideal for oil/gas downhole tools. With 1.3T residual induction and 0.5%/decade aging rate, our materials ensure decade-long stability in hostile environments.
QD MAGNET’s N48EH-grade NdFeB achieves 52MGOe energy product for EV traction motors. Our proprietary dysprosium diffusion process enhances Hcj to 25kOe at 180°C while reducing heavy rare earth usage by 30%. Partner with our APQP team for material substitution strategies and PPAP documentation.
Our Somaloy®-based soft magnetic composites achieve 3D flux paths, reducing motor weight by 40% vs. laminated steel. With 800MPa transverse rupture strength, QD MAGNET materials withstand 20,000G centrifugal forces. Request torque-density comparison charts.
Our Mu-metal shielding (0.2mm thickness) reduces stray fields to <0.5mT in MRI suites. Featuring 80% cold-rolled nickel-iron, QD MAGNET materials achieve 90dB attenuation at 50Hz. Compliant with IEC 60601-2-33. Request RF shielding effectiveness reports.
