● please write your Question clearly. I am unable to understand your Question.

Answer 2

• Copper, brass, and bronze are part of a category of metals known as “red metals”, which are characterized by their reddish tint. While copper is a pure metal, brass and bronze are copper alloys (brass is a combination of copper and zinc; bronze is a combination of copper and tin).

• Perhaps the best way to distinguish between brass and bronze is through their color. Brass usually has a muted yellow shade, much like dull gold, which makes it a good material for furniture and fixtures. Bronze, on the other hand, looks almost always a reddish brown.
