the aluminum cans don't attract and and steel attracts because its is made of iron and aluminum is not.
A 'tin can' is actually made of steel, which is a magnetic alloy of iron. There is sometimes a layer of tin (or zinc), electroplated onto the surface, so the name is misleading. It is more properly a 'tinned' can as it is a steel can which has been 'tinned' to stop it from corroding.
Magnets will pick up steel cans, lifting them away from a solid waste stream. Additionally, rapidly changing magnetic fields can be used to "pop" other metals out of a solid waste stream, through current induced in those metals.
A magnet can sort the ferrousmetalse.g., iron and steel, from the feed stream.

They are made of several different metals, including steel, copper, aluminum and silver. Many are made of some sort of core (steel, copper, gut, or various plastics) and then wrapped with aluminum or silver.

Try different types of strings to find the sound and feel you like best.
