What's the difference between a yellow copper plate and an oxidized copper plate?
Brass, an alloy of copper and zinc, has a hard texture, high strength, corrosion resistance, and oxidation resistance. If you want to choose, brass will be better.
Not resistant to oxidation, rust, rust green (copper) or black (copper oxide).
The so-called pure copper, copper, basically can be regarded as the same concept, the main components are copper elements, conductivity, thermal conductivity are relatively high, on time, soft texture.
