What kind of resource provides summary data on how given kind of aluminum yields to machining? Are there norms, or such?
Different kinds of metals yield to machining differently; e.g. MO-59 brass has a small addition of lead, which makes it leave a clean, smooth cut; in contrast pure copper will pull, crease, drag into threads; where the milled surface of brass left a mirror shine, copper left a fleece-like mess of metal turned into myriads of tiny wires.
The data for a few materials I worked with, I got through word-on-mouth, or own experimentation. I know resources exist, from which professionals learn this in an organized manner, but I don't even know what keywords to look for.
