scrap is made of. If the magnet sticks to the scrap, it is probably a

a nonferrous material.
This is a test for the machinist type, but if you have a grinder you can

steel and if there are no sparks it is make of aluminium. Experienced
machinists can actually tell what type of material it is from the type of
