An aluminum brick, aluminum wire, and aluminum foil have the same density because density is a property of the material itself rather than its shape or form. Density is defined as mass per unit volume; since all three objects are made of pure aluminum, their mass-to-volume ratio remains constant regardless of their physical dimensions. Thus, despite differences in size and shape, they all exhibit the same density characteristic of aluminum.
Malleable, brittle, ductile
Standard aluminum foil is typically around 0.016 mm thick.
A brick wrapped in foil is a cooking technique where a brick covered in aluminum foil is placed on top of a food item, such as a chicken or sandwich, while cooking. The weight and heat conductivity of the brick help to press and cook the food evenly, resulting in a crispy and tender texture.
The density of the foils is the same. They are both pure aluminum, and they each have the same weight per unit volume (density). But the thicker "heavy duty" foil will weigh more for a given area of foil removed from a roll. This makes sense because the heavy duty foil is thicher, and something like, say, as square foot of this heavy duty foil will outweigh a square foot of "regular" foil.
A piece of aluminum foil typically exhibits a metallic luster. This shiny, reflective surface is characteristic of metals, allowing it to reflect light effectively. The smooth texture of the foil enhances its luster, making it appear bright and silvery.
Malleable, brittle, ductile
A piece of aluminum foil has a fixed mass and volume, it is flexible, and it is a metal that can conduct electricity.
The aluminum foil is smoother.
Standard aluminum foil is typically around 0.016 mm thick.
When you fold aluminum foil into a small piece, it can be used to charge a dead battery. The electrical charge is present when it is folded up.

When a small piece of aluminum foil reacts with sulfuric acid, it will produce hydrogen gas and aluminum sulfate as products. The reaction is exothermic, so heat may be observed. Additionally, the aluminum foil will dissolve as it reacts with the sulfuric acid.
Crumpling aluminum foil into a ball would not change the mass of the foil, as the amount of material remains the same. However, the volume would decrease as the foil is compressed into a smaller shape, leading to a higher density due to the same mass being packed into a smaller space. The weight of the foil would remain the same regardless of its shape.
We can't tell that from the density. All we know is that however much aluminum foil you have ... whether it's a tiny scrap or a truckload ... each cm3 of it has 2.7g of mass.
an element. its made entirely out of aluminum
