an alloy that fights germs, makes music, and outlives the empires that cast it
means A yellowish metal alloy of copper and zinc, prized for its durability, antimicrobial surface, and bright musical tone — also slang for nerve, money, or high-ranking officers.
from From Old English 'bræs,' a word for a hard metal whose deeper roots are genuinely murky — it has no clear cousins in the other Germanic languages, which is unusual and has long puzzled etymologists. The many figurative senses came later: 'brass' as cheek or audacity (as in 'brazen,' literally 'made of brass') from the metal's hard, unblushing face; 'top brass' for senior officers from the gleaming insignia and buttons on their uniforms; and 'brass' for money in British slang, perhaps echoing the old proverb 'where there's muck there's brass.'
