Aeronautic materials equivalence 3

[jokerbenj]

Dear forum members,

I am looking for a good reference (book, website or else) to define the alternate materials to the ones classically used in aviation and using US norms:
- aluminum 2024
- aluminum 7075
- aluminum 6061
- stainless steel 301-304
- steel 4130-4140
- ...

I have found two books on the market, but it seems they are quite old:

http://www.normas.com/ASM/pages/05192G.html

Do you have any idea where I can find a reference (from a well-known and trusted organization) where I can find the equivalence between US/French/German/Japanese/... norms?

Thanks for your help!

The two ASM books in your link are considered some of the best available for your purposes. Funny that you think 8 years makes them old. The civil aviation industry barely moves in 8 years regarding new materials.

Other references include Stahlschlussel and Aluminium Schlussel:

In truth you need to identify the relevant specifications and BUY them, and READ them.
Then you will know.
I would never trust someone elses evaluation of a spec if I was going to be responsible for any of it.

jokerbenj-

2024, 6061 and 7075 aluminum alloys that are currently used in the US aircraft industry are covered by AMS specifications. The custodian of these specifications is the SAE. 4130 and 4140 alloy steels are not used much in the US aerospace industry, nor are 301-304 cres alloys.

You can purchase the AMS material specification for any particular aerospace metal alloy from the SAE. If you want to know what the accepted industry material properties are for these metals, in various forms such as sheet, bar, forging, etc, you can look them up in MMPDS-01. If you want to know what the foreign equivalent is to any AMS-spec material, you will need to compare the properties published in MMPDS-01 to the similar foreign standard.

Hope that helps.

There are fair amounts of 4130/4140 used, as well as 304, 316, 321, 347, and 21-6-9 stainless steel.
The vast majority of these alloys are used in the form of tubing.

Dear all,

Thanks for your feedback.
The goal of this question is to find other suppliers of metals whatever the shape is (sheet, plate, tube, bar, extrusion, etc).

My company being in Europe, it is much more convenient to buy French/German/English standards.

I have now two solutions: either buy single datasheets and compare or find an approved document containing it. Because most of those EU standards (3.1363, 3.4363...) have been used on old Airbus (A320 series for example), the alternates are defined in the SRM.

But finally, I think I will have to buy some non-official books at least to find some other standards which I will have to prove by comparison of datasheets.

Thanks for your help!

EdStainless,

Thanks for the correction. I should have been more specific in my post. What I meant by "metal alloys used in the US aerospace industry" are those used for structural applications, and which require controlled composition and well defined mechanical properties. As you noted, 300 series cres alloys are commonly used for non-structural applications such as tubing, fluid fittings, ducts, brackets, clamps, etc. Because they are not used for structural applications, MMPDS-01 does not contain mechanical properties for most 300 series cres alloys.

21-6-9 stainless used for hydraulic lines.
17-7PH, 17-4PH, 13-8PH all used for structural parts.
300 series no so much, just in some very old designs.
