I remember in the late 60’s when aluminum prices went to the moon. Municipal street lamp posts started disappearing in the wee hours.



I’ve lived long enough that I’ve tried forecasting the price of nearly everything at one time or the other. Generally I’ve been wrong. Something unexpected in the market happens.
For example. I’m the 60’s they started using alum for soda cans as I recall. Mid 70’s it was introduced in beer cans.
Now the metal is so cheap that will spark a new massive use of one kind or the other. For example, Ford’s f150 and Range Rover bodies are alum and considered superior bringing higher $. They will likely vastly expand the use. I guess the big question is, how much will China flood the market !
