Abundant element alloy enables rare earth free cryogenic cooling
Tokyo, Japan (SPX) Feb 04, 2026
In collaboration with the National Institute of Technology (KOSEN), Oshima College, the National Institute for Materials Science (NIMS) has developed a new regenerator material composed solely of abundant elements such as copper, iron and aluminum that can achieve cryogenic temperatures around 4 K (minus 269 degrees Celsius) without using any rare earth metals or liquid helium. The work targets
