The High-Temperature Magnet Master

While Neodymium provides the raw “muscle” for general applications, Samarium is the heavy-duty hero of the permanent magnet world. When environments reach searing temperatures, such as inside a jet engine or a high-speed motorsport motor, standard magnets fail. SamariumCobalt (SmCo) magnets, however, maintain their incredible magnetic strength and refuse to degrade.As a trusted UK manufacturer, Less Common Metals (LCM) is a recognised expert in the highly specialised permanent magnet sector. From our facility in Ellesmere Port, we supply the premium-grade Samarium alloys that global defense and aerospace industries rely on as a mission-critical “insurance policy” against thermal demagnetisation.

Samarium Capabilities & Technical Grades

At LCM, we utilise Vacuum Induction Melting (VIM) to master the complex chemistry of Samarium. Our expertise focuses on:

  • High-Curie Point Grades: SmCo alloys (1/5 and 2/17) that can withstand temperatures above 700°C without losing magnetic properties.
  • Corrosion-Resistant Intermetallics: Specialised multi-component systems designed for harsh environments where chemical stability is as vital as magnetic strength.

High-Purity Deposition Targets: Pure or alloyed Samarium targets for thin-film sputtering in electronics and magnetic storage media.
