Corrosion prevention is the practice of reducing corrosion in basic metals such as copper, brass, steel, cast iron, and others. Corrosion, the gradual rusting or wearing down of metal, is an important problem for products made of metal and alloys during storage and transit. Corrosion occurs when moisture and temperature reach a level that begins an electrochemical process that can damage metal products. It is estimated that United States companies spend $300 billion dollars every year to combat corrosion
