Material Comparison

Material Comparison

Material Comparison

(OP)
Hello;

I would like to ask that you know any material comparison resource.

I need to compare some metal material.

Such as;
A743 CA6NM vs A743 Gr. CA-15
AlSl 420 vs A182 F6a Class 3 etc.

Thank you

Do you have the standards with you. If yes,read them and ask your doubt.

Hello;

I would like to ask not standard, I am asking specs of materials which means strength, contents etc..

Thanks

RE: Material Comparison

You can find composition by looking up the UNS numbers.
And the UNS listing also gives all of the specification that cover that composition.
Buy the UNS book.

The properties will have to come from product specs (ASTM and such). This is because the properties are dependent on the product form and processing.

RE: Material Comparison

1. Materials typically used in Aerospace... we have four [4] great documents for mechanical and physical properties...

1.1 MIL-HDBK-5J DEPARTMENT OF DEFENSE HANDBOOK METALLIC MATERIALS AND ELEMENTS FOR AEROSPACE VEHICLE STRUCTURES
MIL-HDBK-5J was last version before release of superseding MMPDS-01 [both issued in 2003]
http://quicksearch.dla.mil/ [search Document ID 'mil-hdbk-5j']


1.2 MMPDS-xx [now up to version -11, 2016] METALLIC MATERIALS PROPERTIES DEVELOPMENT AND STANDARDIZATION
Subscription to IHS Standards Expert or purchase from Battelle Memorial Institute

1.3 AEROSPACE STRUCTURAL METALS DATABASE [formerly known as AEROSPACE METALS HANDBOOKS – ASMH]
https://cindasdata.com/products/asmd

1.4 ESDU: Metallic Materials Data Handbook [SI units, alloys specific to EU and rest-of-the-world]
https://www.esdu.com/cgi-bin/ps.pl?sess=boeing99_1...

2. For more conventional [construction and mechanical] grade metallic materials I suggest...

STRUCTURAL ALLOYS HANDBOOKS [SAH]

3. NOTEs

3.1 Only the MIL-HDBK-5J is free and is obviously +13-years old. Copies of the other documents should be some available thru company or university libraries or by subscription or by direct purchase.

3.2 These references are invaluable for being ‘authoritative’, IE: having material-specific properties that are generally accepted as statistically suitable for design without further ‘proof’ [FAA, JAA, etc].

3.3 CAUTION: welding and other processes that can metallurgically alter these materials [such as platings/aggressive-coatings/etc] especially on very high strength materials... or unique operation environments [seacoast, arctic, space, etc]... always require process verification and validation testing for ‘project-specific allowables’.

RE: Material Comparison

Material comparison resource? Use ASTM A743 and A182 material specifications.
