Not if the pellets are solid. Aluminum will sink in water because its density (2.7g per cc) is greater than water (1.0g per cc).
yes
A thin aluminum foil can float on water if placed carefully flat on the surface because of the surface tension of water. If you were to submerge it, the foil will sink.

A thin aluminum foil, (which is denser than water) could float on the surface if carefully placed, by virtue of the surface tension of water. But if submerged, the foil would sink due to its higher density. 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. (An aluminum boat would float because it displaces a greater mass of water than its own weight.)
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.
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.

Aluminum.
Just fill a container with water. The aluminum is light, and less dense than the water, so it will float to the top of the container. The lead is heavy, and more dense than the water, so it will sink to the bottom of the container. You can then separate the two easily.
Answer #1: float.==========================Answer #2:The density of aluminum is 2.7 gm/cm3.So, just like steel, if you shape a piece of it just right so that it displacesenough water, you can make it float. But a lump of it will sink in water.
The aluminum foil is less dense than the water which makesit float. Aluminum foil is not less dense than water. It is more dense. The reason that aluminum foil floats is that the surface tension of the water will hold the sheet of foil. If you still think that the aluminum foil is less dense than water, try floating a roll of foil in a bucket.
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.
