Any applications in F1? Could this technology carry over into the camera field? I do notice use of magnesium castings now on some digital cameras. Looks like a good materials application as that stuff is light and much easier to cast than Ti. Regards, Dennis PS: right about the thermal coefficient for Ti in cookware. I think Ag has the best coefficient but a bit expensive compared to Cu. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
