What is the composition of Brass?

Part one: Introduction to Brass

• Brass is an alloy.
• These alloys' main constituents are copper$\left(Cu\right)$ and zinc$\left(Zn\right)$.
• Brass is used in musical instruments, cartridges and screws.

Part two: Composition of Brass

• Brass has a higher composition of copper$\left(Cu\right)$ and lower composition of zinc$\left(Zn\right)$.
• The composition is $80\%Copper\left(Cu\right),20\%\hspace{0.17em}Zinc\left(Zn\right)$.

The composition of Brass is $80\%Copper\left(Cu\right),20\%\hspace{0.17em}Zinc\left(Zn\right)$.
