Nickel (Ni)

About Nickel. Despite being extremely common, nickel spent centuries of human history narrowly escaping recognition as a unique metal. As a component of the meteorites that were the only source of iron before its extraction from ore was commonplace, nickel was found in every iron object produced prior to the iron age. As early as 1700 BCE, metalworkers from one Chinese province were highly Get price
