Copper and copper alloys retain a high degree of ductility and toughness at subzero temperatures. In fact, copper alloys become stronger and more ductile as the temperature goes down, retaining excellent impact resistance to 20 K (-253 C or -424 F).
In this section you'll find charts and graphs detailing copper's properties at a variety of extremely low temperatures. They compliment the Mechanical Properties of Copper and Copper Alloys at Low Temperatures (Publication #104/5).
