QD Magnet specializes in high-coercivity ferrite magnets (HcJ 320-400kA/m) for critical applications requiring long-term stability. Our R&D team collaborates with clients to refine magnetic circuits, reduce eddy current losses, and enhance energy efficiency. Equipped with a 20,000㎡ production base and automated inspection systems, we guarantee 100% batch consistency. Explore our portfolio of rings, arcs, and blocks – all backed by a 3-year performance warranty.
As electric vehicle production surges, QD Magnet delivers automotive-grade ferrite magnets meeting IATF 16949 standards. Our corrosion-resistant zinc-coated magnets excel in EV traction motors, battery sensors, and charging systems, offering:
• High coercivity (HcJ ≥320kA/m) for vibration resistance
• Thermal stability across -40°C to +180°C operating ranges
• Custom multipole magnetization for compact motor designs
With 80% of components produced in-house, we ensure supply chain transparency and 45-day lead times for Tier 1 suppliers. Leverage our material test reports (MTRs) and PPAP documentation to accelerate your qualification process.
QD Magnet supplies biocompatible ferrite magnets for MRI equipment, surgical robots, and drug delivery systems. Compliant with ISO 13485 medical device standards, our magnets offer:
• Non-toxic epoxy coatings validated for skin contact
• Ultra-low magnetic decay (<0.5% over 10 years)
• Micro-tolerance grinding (±0.05mm) for miniature assemblies
With Class 1000 cleanroom production and 100% eddy current testing, we meet critical healthcare industry requirements. Download our medical-grade material certifications or request sterile-packaged samples today.
QD Magnet’s ferrite magnets drive efficiency in wind turbine generators and solar tracking systems. Engineered for harsh environments, our Y35-grade magnets feature:
• Anti-demagnetization stability at 150°C continuous operation
• Epoxy/nickel coatings for salt spray resistance (500+ hours)
• Custom radial magnetization for torque optimization
Our vertically integrated facility enables large-diameter ring production (up to 300mm) with 0.2mm axial parallelism tolerance. Backed by 12 R&D engineers, we help renewable energy providers reduce LCOE (Levelized Cost of Energy) through durable magnetic solutions.
QD Magnet’s ferrite magnets deliver unmatched stability in motor applications. Engineered for high coercivity and temperature resistance (up to 250°C), our magnets reduce energy loss in automotive starters, pumps, and HVAC systems. With ISO 9001-certified manufacturing, we ensure ±1% tolerance consistency across batches. Customize dimensions, magnetization patterns, and epoxy coatings to match your design requirements. Partner with QD Magnet for magnets that outperform industry lifespan benchmarks.
