Cryogenic Properties of 90-10 and 70-30 Cu-Ni alloys


Cu-Ni alloys Flange and Pipe Fittings


Copper and copper alloys were the first metals used in the fabrication of low-temperature equipment for the liquefaction and storage of cryogenic fluids. Copper and many copper alloys retain ductility at low temperatures. Their unusual properties of retaining ductility at low temperatures and exhibiting good thermal conductivity is advantageous for heat exchangers and other components in cryogenic plants and in low-temperature processing and storage equipment.


The table below shows that 90-10 and 70-30 Cu-Ni alloys become stronger while still retaining good ductility as temperatures decline. They also retain excellent impact properties.
