While it's true that you can find mechanical property data by searching Google, often you can find better property data by searching in vetted databases accessed via the library. These databases contain information on a wide variety of materials and properties, but you may still need to search more than one to find what you're looking for.
Below you'll find suggested databases for starting your properties search. If you can't find what you're looking for, email me!
Not all of the items in our collection are available online, and that includes our books on materials properties.
Properties for many alloys can be found in the Library's Standards Center (Room 161), in the Aerospace Structural Metals Handbook. We also have a print copy of the ASM Handbook in the Standards Center.
You can also find materials property information in our reference collection on Tier 2, in the call number range TA459-483. If you need help navigating the collection, let me know!
