These four metal cylinders have equal volume but different mass to demonstrate variations in density and specific gravity. The cylinders are 1/2" diameter and x 2" long. You get one each made of aluminum, steel, brass, and copper. These are also called specific gravity cylinders or equal volume cylinders.
The true densities for these density cylinders are:
Aluminum - 2,700 kg/m3
Brass - 8,600 kg/m3
Steel - 7,874 kg/m3
Copper - 8,960 kg/m3.
