Material with high strength-to-weight ration

[sarar]

I am looking for a comparison of materials with high strength-to-weight ratios, is there a website or otehr publication that may help me find and compare materials that fit my criteria?

You can perform property searches using matweb. MIL-HDBK-5H is a great source of information on high strength materials. The following links should get you started:

If you have any access to Ashby charts or any of his (Ashby's) texts on materials selection you might find them really useful.

While you're at it, probe strength to wt at various oper temps. At certain temps the advantage crosses over from material to material. GE had a chart that showed strength to wt vs. temp, which is enlightening.
