In response to yet another frame materials question, I thought it might be useful to start with a more answerable question. One answer per material please, with an example of a bicycle frame using that material.
Please use the format I've used in my answer(s) to make it easy to compare materials.
I see no harm in having all 400+ steel alloys listed if someone wants to do that, but "steel" must specifically be low-grade mild steel rather than a specific alloy. Likewise for aluminium, titanium, magnesium and other metals.
For composites, including metal composites, I would again prefer specific examples with details (there's a big difference between steel reinforced concrete and kevlar/polyester composites). I would also love to see weird and wonderful bikes included.
