 My sister insists that her wooden Alphorn is a brass instrument, but
 that a brass saxophone is NOT a brass instrument. 
Of course--it all depends on the sound-making mechanism.  A plastic
cornet is still a brass instrument, as is an ophicleide or a serpent
being labrosones.   The actual construction material doesn't really
matter.   A metal clarinet is still a woodwind as is a saxophone or a
flute or bassoon.   So a contrabass tuba fitted with a contrabassoon
bocal is technically, not a brass instrument; neither is a tromboon.
