No video, only audio. Nickel, Monel = nickel + copper, Memory metal = nitinol = nickel + titanium, inconel = nickel + chromium = very hard, nickel catalyst used for hydrogenating margarine.

Steel alloy in jet engine, fails above 500C. Tungsten too heavy. Best balance of properties from single crystal nickel + chromium + 9 other elements (Co, Mb or W for high temperature strength, Al, Mg, Ta, Re). Gas stream 1750 C, cooled by 650 C air within the blades, covered by white ceramic coating.

Rhenium, one part per billion in the Earth’s crust. 75% of mined rhenium goes into turbine blades like those in jet engines. Rhenium reduces(?) creep at high temperatures.

Front of jet engine is titanium, tip of nosecone is rubber for de-icing.

yeah I think you are correct buffy, very clever.

In terms of actual information, Meet The Elements by They Might Be Giants is better. Also the clip is great. It’s been among my lad’s favourite songs for three years.

LOL. Reminds me of Peter Weatherall’s song I had stuck in my head for weeks after someone gave Speedy Jnr an educational DVD as a gift.

The polygon and photosynthesis songs got stuck too :/

Just looking at his other videos on youtube; I’m not sure why a young child needs to know the value of a mole.

Moles have a perfect right to play a part in our movement.

Moles & cules, can’t live without them.

Includes for instance five separate episodes on carbon, the one above plus one each on diamonds, materials, energy and plastics. Also includes for instance Chromium, Gold, Helium, two on Iron, Iron-Manganese, Mercury.

Thanks for going to the trouble to write a precis of the episode and backgrounding the other episodes, Moll.
