Brass is a pale-gold alloy of copper and zinc. It is harder than copper alone, takes a good polish and is easier to shape than many structural metals. It resists ordinary corrosion well enough for fittings, containers and decorative work, though its softness makes it a poor choice for blades.
Smiths and founders use brass for sword hilts, buckles, lamps, locks, picture-frame plating and other visible hardware. Instrument makers value its workability and clear resonance when producing horns and other wind instruments. For storage and trade it is commonly cast as a brass ingot.
