anneal AL?
I'm preparing to machine several AL 7075 T6 forgings...
"The Kid" (my son) tells me I should anneal before machining because there will be hard brittle spots. Easy enough to do at the anneal temp of 775 (not sure how long). But, then I haven't got T6 grade 7075 AL anymore. How would I get it back to T6 grade? Or, am I better off with plan "A"? Don't anneal. Karl |
