High-Quality Dysprosium Iron Alloy (commonly called DyFe Alloy, formulDy-Fe) is a specialized rare earth metal alloy composed of dysprosium (a lanthanide element) and iron. It features a silver-gray appearance in ingot or lump form, with a mechanically polished surface for enhanced handling. Our alloy meets strict composition standards: total rare earth metal (TREM) content of 75%-85% and dysprosium purity (Dy/TREM) of ≥99.5%. Highly reactive in air (prone to oxidation), it requires proper storage to maintain performance. As a leading Dysprosium Iron Alloy supplier, we offer three core grades (DyFe75, DyFe80, DyFe85) to cater to diverse industrial needs, from magnet manufacturing to nuclear energy.
The high dysprosium content in DyFe Alloy ensures superior magnetic and magnetostrictive properties, critical for enhancing the performance of neodymium iron boron (NdFeB) magnets and giant magnetostrictive alloys.
Our Dysprosium Iron Alloy is available in three TREM grades (75±1.0%, 80±1.0%, 85±1.0%), allowing precise customization for applications like nuclear fuel dilution (higher TREM) and optical recording (moderate TREM).
Non-rare earth impurities (e.g., C ≤0.05%, Si ≤0.05%, O ≤0.1%) and total rare earth impurities (≤0.5%) are strictly limited, preventing performance degradation in end products like high-precision magnets.
Supplied as silver-gray ingots or lumps with mechanical polishing, DyFe Alloy is easy to cut, grind, and integrate into manufacturing processes. Its stable structure resists fragmentation during handling, reducing material loss.

As a key additive in neodymium iron boron permanent magnets, Dysprosium Iron Alloy improves the magnets’ coercivity (resistance to demagnetization), making them suitable for electric vehicle motors and wind turbine generators.
DyFe Alloy is a core material for giant magnetostrictive alloys—materials that change shape under magnetic fields. These alloys are used in sensors, actuators, and ultrasonic transducers for industrial non-destructive testing.
It enhances the storage density and stability of optical magnetic recording materials (e.g., hard disk drives, optical discs), enabling higher-capacity data storage for consumer electronics and enterprise servers.
In nuclear energy, Dysprosium Iron Alloy acts as a nuclear fuel diluent, regulating neutron flux to improve the efficiency and safety of nuclear fission reactions in reactors.
We provide three grades: DyFe75 (TREM 75±1.0%), DyFe80 (TREM 80±1.0%), and DyFe85 (TREM 85±1.0%). Choose based on your application (e.g., DyFe85 for nuclear fuel, DyFe75 for magnets).
Store Dysprosium Iron Alloy in airtight containers with desiccants or under inert gas (e.g., nitrogen). Avoid prolonged exposure to humid air to prevent surface oxidation.
Yes, its iron component provides thermal stability, making DyFe Alloy suitable for high-temperature environments like electric vehicle motors (operating at 80-150°C) and industrial actuators.
Absolutely—we issue certificates of analysis (CoA) for each batch, verifying TREM content, Dy/TREM purity, and impurity levels, ensuring compliance with your quality standards.
