I would recommend looking at Michael Modest book on Radiation Heat Transfer to assist you with your design. Composition Notes: Aluminum content reported is calculated as remainder.Composition information provided by the Aluminum Association and is not for design. Machining is not considered forming. Hey, I'm looking for a good rule of thumb for normalized emissivity of 6061-T6 Aluminum at 300K that is as-machined. This is the right answer, especially for preliminary calculations-- use both edge cases and see what you get. Aluminum 6063-T5 (UNS A96063). So that is why I would not expect to find values for as machined. Press question mark to learn the rest of the keyboard shortcuts, Aerospace - Spacecraft I&T/Remote Sensing. I'm also interested in finding the normalized emissivity of the same aluminum, but black anodized. I'm sure there are pdf versions online. The thermal conductivity of 6061 aluminium alloy is 150 W/(m.K). You can either adjust the emissivity on the ir, or do math if it's not adjustable. endobj Also, values are often given as a range depending on if the material is oxidized when heated. If you have any questions or good suggestions on our products and site, or if you want to know more information about our products, please write them and send to us, we will contact you within one business day. He wrote the book, literally, on radiation heat transfer and in the appendix he has averaged IR values vs. wavelength for various materials. Thermal Conductivity of Aluminium Alloy – 6061. Typically it is pretty rare to not have some kind of surface treatment on machined aluminum parts that are going to space. New comments cannot be posted and votes cannot be cast, More posts from the engineering community. But everything degrades over time and there's precious little data on the IR properties of paints and metals degrading over the course of 5+ years. The emissivity coefficient - ε - indicates the radiation of heat from a 'grey body' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal 'black body' with the emissivity coefficient ε = 1. 1 0 obj Looks like you're using new Reddit on an old browser.

The emissivity is such a wide range partly because of the surface roughness. We guarantee that your information will not be divulged to the third party.

Aluminum 1100 (UNS A91100). I highly recommend checking out the research from Dr. John Howell. I doubt it will oxidize in an orbital application, but I could be wrong.
