Gadolinium Ferrum Alloy, also known as Gadolinium Iron Alloy or GdFe alloy, is a metal alloy primarily composed of gadolinium (Gd) and iron (Fe). Its chemical formula is expressed as Gd-Fe. The total rare earth metal (TREM) content in commercial grades ranges from 69% to 75%, with a minimum gadolinium purity of 99.5% relative to TREM. Standard products are available as silver grey ingots or lumps, with alternative forms and dimensions available upon request. This alloy is used across multiple industrial sectors due to its specific physical and chemical characteristics.

Gadolinium Ferrum Alloy is used in the production of electronic devices and magnetic materials. It serves as an additive in the manufacturing of neodymium iron boron permanent magnets, and is also a raw material for super magnetostrictive alloys. These components are integrated into various industrial equipment and consumer electronic products.
In the optical sector, the alloy is used in components for laser technology systems. In medical applications, it is utilized in devices that require biocompatible magnetic materials, supporting specific diagnostic and therapeutic equipment production.
Gadolinium Ferrum Alloy is a key material in the production of optical magnetic recording media, leveraging its specific magneto-optical properties for data storage applications.
Standard Gadolinium Ferrum Alloy products are supplied as silver grey ingots or lumps. For industrial production requirements that deviate from standard forms, customized sizes and shapes are available. All batches undergo strict composition testing to ensure compliance with the specified grade parameters, maintaining consistency for large-scale commercial procurement orders.
All commercial grades of Gadolinium Ferrum Alloy have a TREM content tolerance of ±1.0%. For example, GdFe72 grade has a TREM content range of 71% to 73%.
Rare earth impurities are limited to a maximum total of 0.5% across all grades. Non-rare earth impurities are controlled to the specific maximum values listed in the technical specifications table, ensuring compatibility with various industrial manufacturing processes.
Yes, custom sizes and forms are available in addition to standard ingots and lumps. Please provide your specific requirements when requesting a quote for commercial procurement.
The minimum order quantity starts at 1 unit. Flexible volume options are available for both small-batch testing and large-scale industrial production needs.
