Research and application of low temperature cold storage material holmium copper alloy

With the continuous development of the refrigeration industry, conventional cold storage material lead is gradually unable to meet the requirements for use in low temperature areas. Among various types of magnetic cold storage materials, Holmium copper alloy (Ho-Cu) is the most valuable magnetic cold storage material in the industry because of its magnetic phase transition specific heat of 4~10K.

Rare earth alloys are high-quality magnetic cold storage materials that are widely used in the medical and military industries. They have high quality requirements and high added value, which are in line with the national policy requirements for the deep processing of rare earth resources. In this context, magnetic cold storage materials such as Erbium nickel alloy, erbium dysprosium nickel alloy, and holmium copper alloy have been continuously developed.

At present, the main method for producing high-quality holmium copper alloy for magnetic refrigeration in the industry is to use raw material holmium and oxygen-free copper for vacuum induction melting. The quality of the high-quality holmium copper alloy for magnetic refrigeration produced meets the requirements (oxygen content does not exceed 200ppm).
