SUMMARY

The emissivity of Flexinol wire at 70°C and 90°C has not been definitively established in available literature. Users in the discussion suggest contacting the manufacturer for precise values. Additionally, the conversation touches on the relationship between emissivity and contraction rates of Nitinol, indicating that changes in convective heat transfer rates do not significantly affect contraction times, even in a vacuum environment.

PREREQUISITES
  • Understanding of emissivity and its impact on thermal properties
  • Knowledge of Flexinol wire and its applications
  • Familiarity with Nitinol and its contraction mechanisms
  • Basic principles of heat transfer, including convective heat transfer
NEXT STEPS
  • Research the emissivity values of similar materials to estimate Flexinol wire properties
  • Investigate the thermal properties of Nitinol and its applications in robotics
  • Learn about the effects of environmental conditions on material contraction rates
  • Explore manufacturer resources for detailed specifications on Flexinol wire
USEFUL FOR

Engineers, material scientists, and researchers involved in robotics and thermal management applications who require precise thermal property data for Flexinol and Nitinol materials.

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.
