The default material library leaves a lot to be desired and unfortunately it always has. You would think by now at least one dev would be in charge of making sure most, if not all, of the standard industry materials were in the default package from the get-go rather than relying on it's customers to 'fill in the gaps' so to speak. We're not talking about custom kevlar or anything else like that Autodesk. We're talking about regular, everyday, run-of-the-mill raw materials such as the common aluminum, steel and stainless steel grades. It would take a dev less than a day or two to create most of them. But hey, as long as we have thousands of Appearances to choose from..... 
I have been on materials today... We have a set of generic materials which have stupid numbers on the shear modulus, concequently inventor stress analysis will reject them so you have to put a true material in. The problem is there are so many variations and different sources of information. S275J2 steel plate has different properties depending on thickness so we need a material for 1 to 16mm thick, another for 17 to 40mm thick etc
Agreed the autodesk material library is poor, just understand that and create your own, (this used to be a lot easier in previous releases) its a PITA but worth it in the long term and if you decide to build a bridge out of cheese, when the bridge falls down, you know its your fault, not some underpaid, overworked data inputter putting the wrong values in for said material...

timdown73,
There are two methods to provide feedback to the Product Management team responsible for selecting the enhancements made in future version of Autodesk Inventor.
- Leverage the power of the community by adding a feature request as an Idea in the Inventor IdeaStation. Adding Kudos to an idea will increase the likelihood that an Idea will be included in a future release.
- Send feedback directly to the Product Management team via the portal below.
Does anyone want to share their custom material library to get him started?

I have the following, but now I'm worried about the liability issues that timdown73 mentions: 
- Roquefort
- Cotija
- Chèvre
- Feta
- Mozzarella
- Cheddar
- Gouda
- Monterrey Jack
I hope this helps. (forgive me it's Firday afternoon at the end of a looong week!)
Best of luck to you in all of your Inventor cheese related pursuits,
Curtis

What do you mean, most designers are not content with mild steel, we only need three materials, bronze, iron and steel.

Oooo! Fancy-schmantzy will all the modern conveniences, what? We're still having to get by with rock, wood, leather, and clay. ... and the occasional lump of cheddar. 
Mmmm I love cheese
Bob, the only issue with asking someone outside of Autodesk to provide a material library is that Autodesk would still be responsible for checking and correcting any typos in the material properties. So it just seems logical that they do this on their own from the start so they can manage the data and know exactly what is being entered. I agree the best way to get exposure to the devs for improvement is using the Idea Station. I voted on this one submitted last year and it's marked "Under Review" http://forums.autodesk.com/t5/Inventor-IdeaStation/Materials-Materials-Materials/idi-p/3920608. How long under review means you got me. Same goes for "Accepted".
