Which material has the higher density, aluminum or steel?

Steel has a density of ~8g/cc, whereas Aluminum would be 2.7g/cc, so Steel has a density thrice as much as of Aluminum. This also answers why your iPhone is made out of Aluminum rather than Steel! read more

The Mean Density of aluminum varies a little based on the type of aluminum, but it’s generally around 2,800 kilograms per cubic meter. The Mean Density of steel also varies a bit based on the type, but it’s much more dense at 7,850 kilograms per cubic meter. read more

Aluminum is a good reflector of light and heat, making it ideal to use in the manufacturing of reflectors. This material is ductile with a low melting point and density. An advantage that steel has over aluminum is its surface hardness, which is much harder than aluminum. read more
