Copper is generally known as a metal which is excellent in workability and resistant to corrosion. Copper tube has been used in a wide range of heat transfer field.
However, when ant's-nest corrosion occurs on copper tube, the progression rate of corrosion is enough fast to penetrate the tube in the early. In recent years, phosphorus which is added to the copper has been found to have an influence on progression of ant's-nest corrosion.
Test of ant's-nest corrosion on various low-phosphorus content in the copper was clarified the influence of low-phosphorus content in copper for ant's-nest corrosion.
