ergal ta 65 + hard oxidation

[rory_the_king]

Hello everyone!
ergal is the commercial series of aluminum alloys having the best mechanical characteristics!
I found in literature that they match the 7000 series of the astm standard!
someone would tell me:
characteristics of hardness (hb) achieved with oxidation treatment for ta 65? corresponding astm?
170-180 hb? Major?
Is it for remediation?
Thank you.
Lorenzo

can be the 7075 ergal series?
oxidation treatment lasts better wear resistance and abrasion!
but what values of hardness (hv think) are achieved?
oxidation thickness?
Thank you.
Lorenzo

Hello, I've never heard of aluminum bonificato.
Are you sure that ta 65 is not a commercial theme?

Maybe here you can find something that suits you....http://www.aviometal.com/serie7000.phpgreetings

I must have written a big cable!
I don't know if it's a commercial theme.
could be en-aw-7075 t6 (soluble, tempered and artificially aged), but I miss the certainty of what I wrote!

7000 series aluminum alloy identifies the ergal family. respond to heat treatment, they have high traction load (400/500mpa), do not resist much to corrosion and for this reason they must be treated with anodization or coating in seridall (hard anodic oxidation) + teflonatura (treatment of teflonatura to make the pieces smooth). have good workability and resist very well to compssion.

the alloy en aw 7075 that according to the one has acronym alzn5,5mgcu can be supplied according to the en515 various states and in the specific t6 = tempering and surface aging.
rs = 390/490 mpa
rm = 480/540 mpa
hardness brinnel = 30/160 hbAfter coating with hard anodic oxidation + teflonatura, 400/500 vickers of superficial microhardness can be reached for a thickness from 30 to 50 microns of coating.

alzn7,8mgcu: is this the ergal ta 65 possible according to one?

alzn5.5mgcu does not correspond to hergal ta 65!
Right?

But you're the baldassini himself? :biggrin:

hahhaaha pressapoco... Let's say I have my notes of the various years, so I have enough material to survive. then with the ergal I have made some experience, also of treatments and coatings and subsequent processing.

@roy_the_king: I know that it is a state of supply but it is not that of the en 515 but it is something that dates back to old nomenclatures perhaps of the uni 8278.

Why don't you ask your supplier or what's compelling you to use this material if you know what it is?

However if you need a t6 is a t6...they know can also call "pippo" but you need to know what you want.

incorrect courier: brinnel hardness = 130/160 hbI got my finger on the 1...

Right?

is all the same ergal material!!!! supply status is another thing apart.
