Question

How do alloys brass and bronze differ in composition?

Answer 1

A mixture formed by the mixing of two or more metals, or metal and a non-metal is referred to as an alloy. Combinations of metals and other elements can also be used to create alloys. The properties of alloys are frequently dissimilar to the qualities of their constituent components. When compared to pure metals, alloys frequently have greater strength and hardness. Red gold, which is made by combining Copper $\left(\mathrm{Cu}\right)$ and Gold $\left(\mathrm{Au}\right)$, is an example of an alloy. White gold, which is made by combining Silver $\left(\mathrm{Ag}\right)$ and Gold $\left(\mathrm{Au}\right)$, is another major gold alloy.

Both Brass and Bronze are made up of Copper $\left(\mathrm{Cu}\right)$ but in brass the alloying element is Zinc $\left(\mathrm{Zn}\right)$ while in bronze the alloying element is Tin $\left(\mathrm{Sn}\right)$.

Composition of brass and bronze are as follows:

1. Brass - 60% Copper $\left(\mathrm{Cu}\right)$ and 40% Zinc $\left(\mathrm{Zn}\right)$
2. Bronze - 85% Copper $\left(\mathrm{Cu}\right)$ and 15% Tin $\left(\mathrm{Sn}\right)$
