I welded ends on an aluminum square tube to make an air cleaner box. Quenched the material after welding. Went soft and sticky, horrible to machine. Guess I annealed it, copper anneals if you quench it, does aluminum as well, is it better to let it cool slowly or does it matter. The 1/2 plate I used machines fine not welded.
Free advice is worth exactly what you payed for it.
