Supply of High-Purity Rare Earth Alloys for MRI Equipment – California, USA

Client Background

A U.S.-based multinational manufacturer of diagnostic imaging equipment, with a strong presence in North America, Europe, and Asia. The company specializes in MRI (Magnetic Resonance Imaging) systems for hospitals, research institutions, and outpatient clinics. In 2022, the client initiated a supplier evaluation process to identify qualified partners for long-term sourcing of critical magnetic materials.

Project Scope

Hongbang Technology was selected to supply high-purity rare earth metal alloys used in the fabrication of MRI gradient and RF components. The client’s core requirement was stable magnetic performance and material purity for systems operating under precise electromagnetic field configurations.

Technical Deliverables

Material Supplied: Praseodymium-Neodymium (PrNd) alloy with ≥99.999% purity, certified under IC
Product Form: Vacuum-cast ingots and semi-finished blocks, machined to client specifications for internal coil systems.
Magnetic Properties: Designed to minimize hysteresis and ensure consistent field linearity throughout the MRI’s bore section.
Compliance: Supplied with complete documentation for traceability, RoHS compliance, and U.S. FDA-compatible material declaration.

Implementation Timeline

Q3 2022: Small-batch sampling and client-side testing of alloy under simulated load
Q4 2022: Initial order of 500 kg for integration into 50 prototype MRI units
2023–2024: Annual volume increased to 2.5 tons following positive operational feedback and internal certification

Outcome & Impact

The material was successfully integrated into the client’s new MRI model line, reducing magnetic field deviation by 18% in preliminary testing.
No impurities or field inconsistencies were detected during 12-month endurance testing under hospital operating conditions.
Hongbang was formally included in the client’s global procurement system as an approved supplier for rare earth alloy components.
