What are the differences between zinc and iron? - Quora

Since zinc is more reactive than iron, when we galvanize iron with zinc, zinc react with oxygen to form a thin layer of oxide which prevents metal to further corrosion. That thin layer of zinc oxide will protect iron from rusting. In case, if the zinc gets break it will not let iron to get rusted as zinc is more reactive than it, so first zinc undergo corrosion and protect iron for a long time. But if break is bigger then iron may

About 98% of world iron ore production is used to make iron in the form of steel. Iron in cast form has many specific uses (e.g. pipes, fittings, engine blocks) but pure iron is quite soft. Adding a small amount of carbon (usually less than 1%) makes iron into steel which is significantly harder and extremely versatile. There are many different ...
