Base metals

from Wikipedia, the free encyclopedia

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).

Simplified and robust grouping of the elements in the “metals network future” paradigm

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.
