Alusmetallit, also known as base metals, are common metallic elements that are readily oxidized or corroded. In contrast to precious metals, they are generally more abundant and less valuable. Historically, the term "base metal" referred to metals that could be transmuted into noble metals by alchemists, though this understanding has been superseded by modern chemistry.

Common examples of alusmetallit include iron, copper, lead, zinc, nickel, and tin. These metals are widely used in various industries due to their availability, relative affordability, and diverse properties. Iron, for instance, is the backbone of construction and manufacturing, often alloyed to create steel. Copper is crucial for electrical wiring and plumbing due to its excellent conductivity. Lead has applications in batteries and radiation shielding, though its use is increasingly restricted due to toxicity. Zinc is used for galvanizing steel to prevent corrosion and in alloys like brass. Nickel is used in stainless steel and various alloys for its corrosion resistance. Tin is employed in solders and as a protective coating for steel cans.

Alusmetallit play a significant role in the global economy and technological advancement. Their extraction, processing, and recycling are major industrial activities. While less intrinsically valuable than precious metals like gold or silver, their widespread application and necessity in modern life make them indispensable.
