Sintered NdFeB grades specified to exclude heavy rare earth elements, with composition and performance reviewed against application requirements.
Motors, sensors, automotive, export-sensitive programs
Sintered HRE-Free NdFeB magnets are sintered NdFeB grades specified without restricted heavy rare earth materials and reviewed against the same application performance targets.
Useful for programs where dysprosium, terbium, or Dy/Tb content creates export licensing exposure, sourcing friction, or disclosure concerns.
Performance targets stay the same: magnetic output, temperature rating, coating, magnetization, validation, and reliability are still selected around the application.
Axis Magnetics has broad access to Sintered HRE-Free NdFeB, dysprosium-free, and terbium-free options and can propose suitable alternatives for your application.
HRE-Free and HREE-Free refer to heavy rare earth-free specifications. Dysprosium-free excludes Dy, while terbium-free excludes Tb; either term alone does not establish that all heavy rare earth elements are excluded. Confirm the required composition and supporting documentation, then compare the proposed NdFeB grade against the application's output and reliability target.
An HRE-Free option should be reviewed against the same magnetic output, intrinsic coercivity, temperature rating, geometry, coating, magnetization direction, and inspection method as the current specification.
Removing restricted heavy rare earth content can reduce license-related bottlenecks, disclosure pressure, and shipment uncertainty when a qualified alternate can meet the application target. The sourcing review should also confirm origin, documentation, end-use constraints, and customer flow-down requirements.
The practical path usually compares sample output, thermal margin, coating performance, dimensional fit, magnetization fixture feasibility, and any customer-specific origin or documentation requirement.
Review material options, custom specifications, and qualification guidance for the next step in your sourcing program.
It refers to neodymium iron boron magnet options specified without restricted heavy rare earth elements such as dysprosium and terbium.
It can be, depending on the application and industry requirements. Factories can often provide extensive comparison data between HRE-containing and HRE-Free grades in advance, including magnetic output, temperature behavior, coercivity margin, geometry, coating, magnetization, and validation requirements.
