Base metals are non-ferrous metals. To you belong:

Bauxite, aluminum, copper, lead, nickel, tin and zinc

These metals are very commonly used in the industry and are accordingly traded on the LME (London Metal Exchange) as futures.

The following list contains the most important metals and alloy components, no compounds:

• Aluminium: Light metal; Aluminum foil, container, conductor material (electrical engineering)
• lead: Alloys, lead-acid battery, solders, corrosion protection, weight
• Iron: most important metallic material (steel, cast iron), many alloys
• Copper: Electrical engineering (second highest conductivity after silver), bronze, brass
• Nickel: Alloys (nickel-iron, nickel-chromium, nickel-copper, etc.), alloy component (chrome-nickel steel), magnets
• Zinc: Alloy component (brass), zinc die castings (zamak alloy), galvanizing of steel parts (hot dip galvanizing, strip galvanizing)
• tin: Alloy component (bronze), solders (solder), tinplate, pewter figures
