NdFeB

NdFeB alloy flake

Neodymium-iron-boron alloy flake is an essential intermediate material for manufacturing high-performance permanent magnets. Produced at Independence, our fully integrated magnetics facility in Fort Worth, Texas, MP Materials is the only scaled North American source for this vital material.

Product details

Our alloy flake is precision engineered for superior magnetic performance, making it an essential intermediate material for magnet manufacturing.

Tight Microstructure Tolerances

Our advanced manufacturing processes enable us to achieve precise chemical and microstructural control, which is critical for the performance of finished NdFeB magnets. This ensures uniformity and precision, allowing magnet manufacturers to produce magnets with exceptional magnetic properties tailored to specific applications.

High-Performance Applications

We collaborate closely with customers to engineer NdFeB alloy flake compositions optimized for specific downstream magnet compositions. Our flake is particularly suited for high-performance applications, enabling the creation of magnets that perform reliably under extreme temperatures and demanding conditions.

Locally Sourced & Traceable Supply

Our NdFeB alloy flake is produced from domestically-sourced materials tracing back to Mountain Pass in California. This local sourcing enhances supply chain resilience and guarantees the provenance and quality of raw materials, supporting our mission to build a diverse and resilient U.S. supply chain for magnet manufacturing.

Integrated Analytical Capabilities

Our Independence facility houses an 8,000 square foot pilot plant and an integrated analytical laboratory equipped to perform Inductively Coupled Plasma (ICP) spectroscopy, combustion analysis, inert gas fusion analysis, profilometry for surface measurements, optical microscopy for detailed structural inspection, and Scanning Electron Microscopy (SEM) for high-resolution imaging. These comprehensive analytical capabilities ensure tight quality control, allowing us to consistently meet and exceed customer specifications.
