Brass is primarily composed of copper, typically making up around 60-70% of the alloy, and zinc, comprising about 30-40%. The specific composition of brass can vary, and other elements like lead, tin, aluminum, or nickel may be added to achieve certain properties or characteristics.

Brass has a distinctive warm golden color, which gives brass castings an attractive and aesthetically pleasing appearance. It is often used in decorative and artistic applications due to its lustrous and shiny surface.

Brass offers good resistance to corrosion, making it suitable for various indoor and outdoor applications. However, its corrosion resistance may vary depending on the specific composition of the brass alloy.
