Copper corrosion

Copper corrosion occurs when copper reacts with elements like oxygen, moisture, or acids in the environment. This reaction causes the copper surface to change, forming substances such as copper oxide, carbonate, or sulfate. Over time, these forms can give copper a greenish or bluish patina, like the Statue of Liberty's surface. While this coating can protect the underlying metal from further corrosion, excessive deterioration can weaken the material. Factors like weather, pollution, and water exposure influence how quickly copper corrodes. Proper maintenance helps prevent or slow down corrosion, ensuring the metal's longevity and structural integrity.
