Soft magnetic composites are used in a wide range of applications working in different environmental conditions, between others, in different temperatures. Nowadays, devices often work in cryogenic temperatures. The paper shows influence of liquid nitrogen temperature on mechanical properties of soft magnetic composites prepared from ABC100.30 powder bonded by epoxy resin. Mechanical properties of samples were measured in room and liquid nitrogen temperatures. Compressive strength and transverse rapture strength increase with decreasing temperature. This type of soft magnetic composite can be applied in magnetic circuits of devices working in cryogenic temperatures. The results of measurement show that new devices, especially electric machines, working in these temperatures can be designed with higher mechanical loadings than devices working at room temperature.
