This is why i created this thread was to see some different composites and alloys.

I think he might have been referring to "chrome-moly," which is a steel alloy of iron, molybdenum, chromium, and sometimes manganese. It's a common material in high-end bicycle frames, especially in Italian or custom-made bikes. It is heavier than aluminum, per unit volume, but has better ductility, and can be brazed or welded. The lightest bicycle frames now are composites, but right behind those are aluminum and chrome-moly. It's been a few years, but a favorite chrome-moly tubing around 1970 was Reynolds 531.
Most carbon fiber composite parts are mind-bogglingly expensive. I would be interested in hearing more about how you are thinking of fabricating composite components.
