aluminium a380

[vale61]

Hello everyone
I am looking for the thermal characteristics of the a380 alloy, in particular I would like to know the k (thermal conductivity) (on the web I couldn't find it).

It is that I also have the doubt that the alloy indicated to design is not correct, the piece is in fact milled from the full, while the a380 seems to be from foundry.

However, I would like to see if it is really so advantageous (in terms of heat dissipation) compared to the most available anti-rodal.

Thank you 1000.

hi on a text I used for the examination of metal materials I found the following data, are you sure of the alloy? I have never seen it mentioned in any slide book I have on the topic . I leave the data hoping to be useful to you

thermal conductivity (science and engineering of materials - an introduction - w.d. callister)

aluminium alloys
1100 (remember) 222
2024 (remember) 190
6061 (remember) 180
7075 - t6 130
356.0 - t6 151

Are you sure about the league? I've never seen her mentioned in any slide book I have on the subject.

Did you see the document I linked just above?

greetings

try also here: http://www.matweb.com/However to the eye the coefficient of transmission of the heat is lower.

Hi.

 

[vale61]

Okay, I read everything.

problem solved, as I thought it was put a wrong drawing theme.

I'm going with the anti-rodal.

Thank you 1000.

I think we responded almost at the same time, just because vale61 seemed doubtful.

ps interesting that site:finger:

hi, since you eventually oriented with anti-rodal, I would propose the 6082 alloy... is perfect for machine tool processing, has k =175, and is much more resistant to corrosion than 6060.

I needed it for nautical applications (of course not in direct contact with water) and it was a success!

Thanks for the advice, I think I can serve in the future.

I apologize if I break the boxes but since you are on nautical applications you have or are aware of some relationship/site/document/text that say something about corrosion resistance maybe even in aluminum alloys salt mist and possibly the effectiveness of surface treatments (surtek, anodization, epoxy powder check...)?

we say that the corrosion problem for this piece should and must be the last of the problems, is inserted in an ip67 box (o-ring etc.).

hello, unfortunately are not aware of norms or technical documentation on corrosion resistance of aluminum alloys. You could see in the "naval" forum. ..but you're gonna throw something out between the old posts.

returning to aluminum alloy take a look at the various technical cards of the site:
http://www.comefimetalli.it/html/le_leghe.htmps: I am not specialized in nautical applications, it is only a job that happened to me randomly.

try to find din 50021 or uni iso 9227 (test in saline fog)

Thank you.
