When we decide to purchase brushed NICKEL plate, we will consider several factors, such as the raw materials , specifications and prices of brushed NICKEL plate, so as to select a supplierswith good factors in all aspects.BaoJi Yuan Da Metal Materials Co., Ltd is your best choose，we share NICKEL knowledge，  that is the development history of nickel .

       Nickel is a member of the eighth group of metal elements in the Mendeleev Periodic Table of the Elements and is a member of the Fe, Co, and Ni-iron tri-elements. Nickel's Latin name is Niccolum (Ni).

       （1）The origin of nickel

       The naming history of nickel is similar to that of cobalt. The miners of the Middle Ages called Nickel the devil of the miners. This is the “Kingfernickel” (copper devil)—false copper.

        This ore is similar to copper on the surface. At that time the glass manufacturing industry tried to use it for glass coloring (green), and the copper in the ore but failed, because there was no such copper at all.In 1751, Axel Cronstedt, a Swedish mineralogist, studied the red copper-nickel crystals (red nickel pyrite NiAs) of this kind of ore, and separated them from it. A new kind of metal occured, he called it nickel.

       （3）The exploitation of nickel in the world

       As early as 235 BC, China began to use nickel minerals to make coins ，including 78% of copper and 20% of nickel.In Europe, similar minerals were discovered in 1094, but because they did not recover nickel from the minerals, so be called "red nickel mines," also known as "copper devils."Nickel is widely used as a precious metal-containing currency and is also used in electroplating to manufacture anti-corrosion layers.The main minerals of nickel - red nickel ore (red arsenic nickel ore) NiAs, austenitic nickel ore NiS, and sulfurous nickel ore (FeNi) 9S - all contain arsenic, iron and sulfur, of course, in the ferromagnetic pyrite Sulphurite also exists.Other ores that mine nickel generally contain impurities such as Co, Cu, Fe, and Mg.Nickel is generally the main product of the refining process but is recycled as a by-product in the production of other metals.The world’s largest producer of nickel is Russia, Canada, Australia, Cuba, New Caledonia and Indonesia.
