Can Copper Corrode?
Generally no-even after centuries under soil-but there are some underground situations where it can, including: abnormally aggressive soils localized and long-line-type concentration cells created by differences in soil composition the action of stray direct currents (DC) flowing in the ground faulty design and workmanship certain conditions created by alternating currents (AC) thermogaivanic effects galvanic action […]
