RE: Was there really an aluminum "breakthrough in processes?

Both aluminum and steel use heat treating to make the materials stronger.
As mentioned in an earlier post, wider tubing and shapes allowed thinner tubing and lighter frames.

There is also diff mixes added to the steels to improve characteristics such as tenacity, fatigue resistance, workability and insensitivity to overheating. https://gravelcycling.wordpress.com/...n-bike-frames/

I can for sure tell the diff between my Italian racer with Dedacci 7003 Heat Treated Aluminum vs my bikes with diff types of steel, TI & carbon. The major diffs are stiffness and road feel (vibration dampening)

YMMV
