Nickel was used industrially as an alloying metal almost 2,000 years before it was isolated and recognized as a new element. As early as 200 bce the Chinese made substantial amounts of a white alloy from zinc and a copper-nickel ore found in Yunnan province. The alloy, known as pai-t'ung, was exported to the Middle East and even to Europe.
