- Steel is typically a silvery-gray color, while brass is a yellow or golden color due to the presence of copper.

2. Density:

- Steel is denser than brass. The density of steel is around 7.8 g/cm³, while the density of brass is around 8.5 g/cm³.

3. Hardness:

- Steel is harder than brass. The hardness of steel is around 5-6 on the Mohs scale, while the hardness of brass is around 3-4 on the Mohs scale.

4. Malleability:

- Brass is more malleable than steel. Brass can be easily shaped and worked, while steel is more rigid.

5. Ductility:

- Brass is more ductile than steel. Brass can be drawn into thin wires, while steel is less ductile and tends to break when stretched.

6. Magnetic Properties:

- Steel is magnetic, while brass is not magnetic. This difference is due to the presence of iron in steel.

7. Spark Test:

- When a piece of steel is held against a grinding wheel, it produces bright, white sparks. On the other hand, brass produces reddish-brown sparks.
