Arnold Magnetic Technologies Our Highest Performing SmCo Material Arnold Magnetic Technologies’ Samarium Cobalt (SmCo) materials break the performance barriers of other magnetic components. Offering several operational advantages, our topof-the-line RECOMA Sm2Co17 alloys are the material of choice for demanding rare-earth magnet applications. Key Benefits Performance at temperature extremes – RECOMA 33E SmCo magnetic materials offer high stability and magnetic output at elevated temperatures. Broad-based source of supply – Unlike neodymium (Nd) magnets, which need high levels of rare dysprosium (Dy) to function at higher temperatures, SmCo magnets use materials that are more widely available. This makes SmCo pricing more stable and less prone to market changes. Corrosion resistance – Arnold’s high-technology coating facilities offer protective coating options that improve resistance to damage in extreme temperatures and other harsh environments. Breadth of Applications Use Arnold’s RECOMA 33E to achieve higher performance and efficiency in your automotive, motorsports, aerospace, defense, industrial, or utility application. RECOMA 33E is most useful: UNDER THE HOOD For Hall sensors, drive components, and energy recovery systems that demand stability and consistent performance over a high temperature range. IN THE AIR For rotor applications that are subject to high temperatures under full operation. IN HARSH ENVIRONMENTS Where other materials are subject to degradation and even failure under extreme operational conditions.
