For example, a high zinc content leads to increased strength and ductility, while the inclusion of manganese results in enhanced corrosionCorrosion is defined as a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air. This reaction causes damage and... More resistance.
