ickeädelmetaller

Ickeädelmetaller, also known as base metals, are a category of metals that are more reactive and readily corrode or oxidize than precious metals. This group includes common elements like iron, copper, lead, zinc, and tin. Unlike precious metals such as gold, silver, and platinum, which are found in a relatively pure state in nature and have high economic value due to their rarity and resistance to corrosion, base metals are typically more abundant and less valuable.

The term "base" refers to their historical association with alchemy, where they were considered impure or fundamental substances that could potentially be transmuted into noble metals. In modern chemistry, their reactivity is a key characteristic. For example, iron rusts when exposed to oxygen and moisture, copper forms a green patina, and lead is susceptible to oxidation.

Despite their lower value compared to precious metals, ickeädelmetaller are crucial in industrial applications and everyday life. Iron is the primary component of steel, used in construction and manufacturing. Copper is essential for electrical wiring and plumbing. Zinc is used for galvanizing steel to prevent corrosion, and lead has historically been used in batteries and piping, though its use is now restricted due to toxicity concerns. Tin is often used as a coating for other metals to prevent corrosion. Their widespread availability and versatile properties make them indispensable materials in the global economy.
