Gadolinium-Based Alloys

Gadolinium (Gd) is a silvery-white, malleable, and ductile rare-earth metal. Gadolinium is one of the more abundant rare-earth elements. It is never found as free element in nature, but it is contained in many rare minerals. Gadolinium does not tarnish in dry air, but it can be oxidized in moist air. Gadolinium reacts slowly with water and dissolves in acids. Gadolinium becomes superconductive below 1083 K, and it is strongly magnetic at room temperature.

Gadolinium-based alloys are compounds that combine gadolinium with other metal elements. For example, gadolinium has useful properties in alloys. As little as 1% gadolinium can improve the workability of iron and chromium alloys, and their resistance to high temperatures and oxidation. It is also used in alloys for making magnets, electronic components and data storage disks.

Alfa Chemistry provides high-quality rare earth alloys at a competitive price. Gadolinium-based alloys we can supply including gadolinium-iron (Gd-Fe) alloys, gadolinium-germanium-silicide (Gd-Si-Ge) alloys, gadolinium-magnesium (Gd-Mg) alloys, gadolinium-cobalt (Gd-Co) alloys. We can customize various shapes of gadolinium-based alloys according to your requirements or drawings.

Applications

Gadolinium-based alloys have various applications, for instance:

• Gadolinium-iron (Ga-Fe) alloy is mainly used in grain refining, hardening, improving alloy performance, in Nd-Fe-B permanent magnet materials.
• Magnesium-gadolinium, as a master alloy, can be used for grain refining, hardening, and improving alloy performance by enhancing properties such as ductility and machinability.
