Base metals
The base metals include metals that are produced in relatively high tonnage and are often used as the main component in alloys . These include iron , aluminum , copper , zinc , lead and nickel (see Figure 1).
Current classifications of metals, which are based on the application areas of the metals, differentiate between base metals, technology metals and accompanying metals . The terms main metals or carrier metals are also used as synonyms for base metals .
Base metals are elementary components of a functioning circular economy . The metal wheel illustrates how the base metals relate to the other metals in nature and in recycling , and what significance they have for the circular economy.
