RECOMA® 33E
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.
