Permanent Magnets

Samarium Cobalt Magnets

Samarium Cobalt magnets are the ultimate choice for demanding applications due to their high resistance to demagnetization, corrosion resistance and excellent thermal stability at elevated temperatures.

KEY BENEFITS

  • Best performance at high temperature for designs with wide operating temperatures
  • Avoids additional coating costs; SmCo has the highest resistance to corrosion
  • Stable performance with high resistance to demagnetization

Samarium Cobalt Magnets (Ultra-High Temperature)

Ultra-High Temperature Samarium Cobalt magnets (first developed by EEC in 2000) are capable of operating at temperatures ranging from 400°C to 550°C.

KEY BENEFITS

  • Performance at extreme temperatures 400°C to 550°C
  • Most applications > 400° should be plated
  • Stable performance stability with high resistance to demagnetization

Samarium Cobalt Magnets (Temperature Compensated)

Temperature Compensated Samarium Cobalt magnets (also first developed by EEC) provide a constant magnetic field strength over a temperature range of interest specified by customers.

KEY BENEFITS

  • Consistent performance over specified temperature range (customizable to requirement)
  • Stable performance with high resistance to demagnetization
