Product Information

Magnetic materials for cryogenic regenerator matrices

Magnetic materials for cryogenic regenerator matrices

Advantages

  • Our material is an environmentally friendly product because it is a substitute for lead.
  • Our material has a large change in specific heat that is produced by magnetic phase transformation under 15 K.
  • Our material is spherical-shaped powder, whose diameter is 100 to 300 µm on average, which reduces loss in gas pressure.
  • Our spherical-shaped powder material is free from deformation or disintegration even after a long period of service.
Comparison of specific heat of various magnetic regenerator materials

Applications

  • Ultra-low-temperature devices (Superconductive devices)
  • Gifford McMahon (GM) refrigerator
  • Pulse-tube refrigerator

The standard diameter of our spherical-shaped magnetic regenerator material is 150–300 µm. We can offer other-sized spherical powders as per your request.
