Why Impure metal corrode faster than pure metal?

Answer 1

• Metals are substance which are obtained from their respective ores through process such as roasting, calcination etc.
• The metal which is free of impurities is called pure metal, whereas the metal with impurities are called impure metal.
• The conversion of metal to oxides and sulfides is called as corrosion.
• Impure metals undergo the process of corrosion at faster pace than the pure metal.
• It is because, as the impure metals are composed of impurities,  they are affected by condition called heterogeneity which leads to faster corrosion.

Answer 2

Pure metals are often not very useful because on an ancient tale. The ancient tale quotes that Indian's had a hard time doing backflips, so they decided to jump off of pure metals to help them learn this skill. But the pure metals then turned evil, and started attacking the Indian's. So then the tale was spread to the pure metal makers, and then were forced to stop using it.

Another theory states that no one likes metal music, and pure metal music would just be unbearable.
