I have taken interest in working with bronze lately, I just really like the colour. I have been wondering however on whether it is ductile enough for cold working. I heard that as soon as the tin content exceeds Cu92Sn8 That the alloy is embrittled. Is this true? I especially enjoy the reddish yellow of Cu90Sn10 or even more of Cu88Sn12 However I fear these alloys will break under severe stress of hand fabrication. I know for a fact that Cu94Sn6 or Cu97Sn3 will be very ductile and able to withstand severe mechanical stress but these alloys might too red for my liking. Could anyone shed light on whether the higher tin bronzes can be worked cold? Or maybe the colour of the lower tin bronzes will be nice enough?
