Somehow I've been tagged to repair/build a new grille and insert for a Fiat going to Pebble Beach. I need to bend some .045 brass sheet. On a test piece on the inside bend it split. Does it need to be annealed? Didn't have time to try before leaving the shop today. Will post pics if it helps.
I would PM Mindover he will know. There might be some info on his thread here: http://www.jalopyjournal.com/forum/showthread.php?t=637003
I do many projects with annealed brass and copper, a dull red is what your looking for (difficult to see in daylight). You wont get many cycles (2-3 bends) out of it before it work hardens on you. At .045" though, it will warp, so prepare to do some flattening.
very much agreed also, remember non-ferrus metals tend to react opposite from steel and iron when quenching "...alloys of copper, aluminum, or nickel, and some high alloy steels such as austenitic stainless steel (304, 316), produce an opposite effect when these are quenched: they soften."
