1) Iron. Far and away, the most useful. The amount of iron and steel produced in the world each year is far more than all other metals combined.

2) Aluminum. Many people don't realize that, when first discovered, aluminum metal was thought to be extremely rare. The French crown jewels have bars of aluminum metal, thought to be a newly-discovered rarity. Later, it was discovered that in various ores and compounds, aluminum is one of the most common metals on Earth. Today, it is used for automotive and aircraft parts, containers, and a thousand other applications.

3) Copper. The most ancient of engineering metals, and the primary ingredient for both brass and bronze. Also, a magnificent conductor of electricity. Although aluminum is actually used for cross-country high-voltage electric power transmission, because its much cheaper and lighter than copper, still copper is the preferred material for housing and electrical and electronic devices.

4) Lead. Roundly disparaged today because of its notorious toxicity, lead is nonetheless a valuable material for rechargable batteries. So much of it is used for that application, and the alternatives for replacing it are so expensive, that one cannot overlook lead's continued contribution to our society. Almost every vehicle in the world has a lead battery in it, as do many rechargable devices.

5) Zinc and tin. But zinc and tin are both extremely beneficial, as alloy additives and as corrosion-resistant coating materials. A great deal of steel used in the automotive industry is zinc-coated for rust prevention, and tin is still the coating of choice for steel to make the famous "tin can" for food storage. Both metals, though seldom used in pure form, are used in huge quantities in conjunction with other materials to provide improved properties and durability.

Tonnages used per year drop off rapidly after these six. Nickel is similar in many ways to copper, with which it often occurs in nature. It is the basis for nickel-based alloys that have certain special applications, but it is fairly rare and more expensive than copper.

Titanium is making inroads as an engineering material in high-tech / high-performance machinery... especially aircraft and the aerospace industry, where its great strength and lower density than steel make up for its high cost. However, titanium remains very expensive to produce, and workable deposits of it are not equally distributed around the globe.

Manganese, chromium, molybdenum, niobium and vanadium all serve mainly as alloying elements in steel.

Gold and silver, of course, are 'precious metals' known since ancient times, and thus rare and very expensive, though they do have some unusual industrial applications that make them worth the extra cost. But on a tonnage basis, they are extremely rare as compared to iron and aluminum.

Chewing it over a bit, having listed many other metals, I'll have to stick with my original list in that order: Iron, Aluminum, Copper, Lead and Tin... plus Zinc. These make up the huge stock of working metals that have sustained human industry for thousands of years, right up to the present day.
