Aluminum is the most
abundant of all the metals. It is a light
metal-approximately 1/3 the weight of copper and 1/4 the
weight of silver.
Aluminum is a good conductor of electricity. It can be cast,
forged, hammered or weld, soldered spun. It is resistant to
sulfuric or nitric acid while hydrochloric acid and strong alkalis
will dissolve it. For craft purposes commercially
pure aluminum with slight impurities of iron and silicon is
used.
