Flute crowns have been made out of titanium, vanadium, copper, zirconium, niobium, nickel,sterling silver, tunsten, tungsten 75%/copper 25%, hafnium & tantalum.
A guided tour of 6 to 8 selected metals (preferably using your favourite flute) would take about 2 hours and demonstrate the surprising power of these materials to effect the performance of your head piece in different ways. There is no obligation attached;I am primarily interested in your reaction.
