Note that brass can blacken after being used for a long time, which is a normal phenomenon. Brass has a certain degree of corrosion resistance. Once it comes into contact with electrolytes such as sweat, it will accelerate the chemical reaction between brass and oxygen in the air, generating black copper oxide, and brass will become black.
