Which metal was once called about a copper that is known about him?

291
Pure copper and metal with a controversial title can not be confused. But the ore of these metals are similar, like twins. Therefore, the Swedish scientist Cronstedt (sometimes written Kronstad) called this metal "false copper". \r\n\r\n\r\n\r\pmetal that almost half a century after its discovery, was called a "false copper" - NICKLE.
