It just goes to show that the pollies have no concept of reality.

Except aluminum, especially in the 5xxx series of alloys. Aluminum alloys have no ductile-to-brittle transition at low temperature. Their performance at low temperatures is so good that they are categorically exempt from ASTM and ASME low-temperature testing protocols. Tensile and yield strengths in aluminum actually increase at cryogenic temperatures, from 10% to 40%. Ooooh, I love it when you talk dirty! (Sorry, but I couldn't resist. As a non-engineer, tech-speak sometimes goes right over my head...)
