I hear global warming is causing the aluminum trees to die. Really sucks. Last year, a 5-day heatwave resulted in an aluminum farmer losing his entire crop.
What are you paying for 6061 in your area? Here in northern CA, where metal suppliers are few and far between, we get shafted at about $5/lb. I can order it online have it shipped, but it still ends up costing around $4.something.
I got a quote from some Chinese supplier a few months back. They wanted $2/lb in 10,000lb qty.
