My theory is that's caused by alkaline perspiration, but I have no formal data to backup my asumption.I have a MVI Bb bari in all perfect condition except for corrosion marks from the first owner (I'm #2) due to high acidic content in his persperation I would guess.
He can turn a silver flute black quickly and had to have and his MVI alto refinished as a result. Perhaps this is covered in earlier or other places on the site.
Any comments on individual player effect on the lacquer and brass after years of player other than normal dings, etc. from lots of playing.
the density is about the same. the rockwell hardness is a little harder but generally 302 stainless elongates more before breaking than brass. tensile strengthe and yield are higher for 302. sounds pretty cllose to me. now cost i believe. it cant be more costly than sterling.Formability, mass, cost, high flow stress necessitating different manufacturing methods...
I've worked on a brass flute - a very old one...can't remember who the maker was though. I think it's the only one I've ever seen.Uebel made a very decent aluminum flute. Matit makes a pro-grade carbon fiber flute using magnets instead of springs. The feel is quite nice. The Guo Bros. grenaditte (basically plastic) flute has been getting a lot of rave reviews from professional players. Funny thing, though--I've never seen a brass flute...
Thanks for the derail. How 'bout starting a thread on alternate materials?i still want a stainless steel sax. maybe passivated. if i recollect right, pitting of stainless is really only in salt environments.
I wonder about an aluminum sax that is anodized. they are great even in salt environs. form it all anealed then heat treat to get it good and hard. it will be lighter than brass ( about 1/3 the weight) and more corossion resistant. hard anodize can be done in colors too. its not as shiny though.
Oddly enough, a stainless steel sax would weigh slightly less than one made of brass. 7400 kg/cu. meter vs. 8400kg/cu. meter.Steel would make a very heavy sax. I think they tried making saxes out of different material in the past and brass wins for being the best for its ease fo use and cheapness.
If you read the stuff on brass it is also good hygenically, so I think brass is one of the best choices.
