Depends on what they're dropped into.
Water - no.
But drop them into something that's denser than aluminium and they will float.
Blocks made of materials like wood or plastic would typically float in water, while blocks made of materials like metal or concrete would sink. The density and composition of the block determine whether it will sink or float in water.
Aluminum powder will sink in water because it is denser than water.
Shape the aluminum to look like a boat, so it displaces enough water to float. The force supporting the aluminum is the buoyant force. It is equal to the weight of the volume of water displaced.
Yes, wooden blocks typically float in water because wood is less dense than water. This means that the buoyant force acting on the wooden block is greater than its weight, causing it to float.
The 1-kg block of wood will float on water, while the 1-kg block of aluminum will sink. This is because wood is less dense than water and has a greater buoyant force acting on it, causing it to float. Aluminum is denser than water and will sink when placed in water.

Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. A thin aluminum foil could float by virtue of the surface tension on water (but if submerged, will sink). An aluminum boat would float because it displaces a greater mass of water than its own weight. An aluminum block could also float on a liquid of higher density.

Some have aluminum engine blocks and/or cylinder heads, many of the sensors, intake manifolds
A solid bar of aluminum would not float, since its density (almost 3 grams per cc) is greater than that of water (1 gram per cubic centimeter). For an object to float in water, its density would have to be less than 1.0.
