Quality Is Engineered From the Source — Not Inspected at the End.

At JH Amorphous, we design and manufacture high-performance nanocrystalline cores and magnetic components for power electronics, renewable energy, EV/charging, industrial automation, and EMC applications.

To ensure the performance and reliability our customers depend on, we implement a rigorous incoming material inspection system tailored specifically for nanocrystalline ribbon and magnetic materials.

Our Incoming Inspection Framework Includes:

• Surface Quality Examination
Detection of micro-defects such as scratches, oxidation, edge burrs, and surface irregularities that may impact magnetic properties or winding performance.

• Dimensional & Physical Verification
Precision measurement of ribbon width, thickness, and uniformity using calibrated metrology tools to ensure compliance with core design requirements.

• Material Consistency & Traceability
Each batch of material is recorded, labeled, and tracked through our digital QMS to maintain full traceability from raw ribbon to finished core.

• Specification Alignment
Cross-checking supplier material certifications, magnetic performance indicators, and mechanical characteristics to ensure alignment with critical application standards.

Why It Matters

Nanocrystalline magnetic cores are central to high-frequency, high-efficiency power conversion. Even minor deviations in material characteristics can affect:

• Core losses
• Saturation behavior
• EMC suppression capability
• Thermal stability
• Long-term reliability

By establishing strict quality control at the start of the value chain, we ensure that every magnetic core and component we deliver maintains consistent performance under demanding operating conditions.

Our Commitment

We do more than manufacture magnetic components —
we engineer reliability into every product, beginning with the materials themselves.

If you are looking for a partner that prioritizes quality, precision, and long-term performance in nanocrystalline magnetic solutions, we’re ready to collaborate.
