Pohjametallin

Pohjametallin is a Finnish term that translates to "base metal" or "nonferrous metal." It refers to a group of metals that do not contain iron, distinguishing them from ferrous metals like iron and steel. This category encompasses a wide range of elements that possess distinct physical and chemical properties, making them valuable in various industrial and commercial applications.

Common examples of pohjametallit include copper, aluminum, lead, zinc, tin, nickel, and precious metals like gold, silver, and platinum, although the latter are sometimes categorized separately due to their high value. These metals are known for their conductivity, malleability, ductility, and resistance to corrosion, among other characteristics.

The extraction and processing of pohjametallit involve mining ores and then employing various metallurgical techniques such as smelting, refining, and electrolysis to obtain the pure metals. Their diverse applications range from electrical wiring (copper and aluminum) and construction (aluminum) to plumbing (lead and copper), batteries (lead and nickel), and coinage (various alloys). The global trade and market dynamics of pohjametallit are significant, influencing economies and technological advancements worldwide. Understanding the properties and uses of these metals is crucial in many scientific and engineering disciplines.
