Emissivity Of Flexinol

  1. Apr 11, 2016 #1
    I searched all over the internet, but I couldn't find it. Does anyone know the emissivity of 70 degrees C and the emissivity of 90 degrees C Flexinol wire?

    Have you contacted the manufacturer?
    I'd make an educated guess based on similar materials.
    I'm guessing from this thread that you're interested in improving contraction rates of Nitinol? There's been quite a lot of research in this area. Convective heat transfer rates don't dramatically alter contraction times so I doubt you'd get a noticeable improvement by going to a vacuum.
