There are many answers for this question. I am basing it from how these metals are used by humans. Steel is a major building material, it is extremely strong and sturdy, welded easily, and the most common metal used by humans today. Aluminum is a very light, medium-soft metal, commonly used in car bumpers, especially in the "Mini Cooper." Gold is both very valuable for its looks, but for its uses too. Gold is commonly used in jewelry, but is even more commonly now days used in high grade electronics. The electric conductivity is extremely useful in these electronics. Copper is a common metal used in heaters due to its amazingly powerful heat conductivity. Zinc is commonly used to cover the corrosive properties and ultimately protect steels and other metals from corrosion. Iron is almost as hard as steel, but not as malleable and tough as it. It is commonly used for building anvils.
