impurities in metals

Impurities in metals are unwanted elements or substances that are mixed in with the pure metal during its extraction or processing. These impurities can originate from sources such as ore material, the environment, or manufacturing processes. They can affect the metal's strength, durability, and appearance, sometimes making it weaker or less resistant to corrosion. Purity levels are important in industries like electronics or aerospace, where high-quality, clean metals are essential. Removing impurities through refining processes helps ensure the metal performs as expected in its specific applications.
