1. What is metallic nickel?
Nickel is a hard and ductile ferromagnetic metal with high polishing and corrosion resistance. Nickel is an iron-loving element. The inner core is mainly composed of iron and nickel. In the crust, mafic rocks contain more nickel than aluminosilicate rocks. For example, the nickel content of peridotite is 1000 times that of granite, and gabbro is 80 times that of granite. 20 17, 17,1October 27th, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted out for reference.

To sum up, the price of metallic nickel in 202 1 year is only about 12000 yuan, which is far from the psychological standard of investors. I suggest you pay attention to it when using it, and don't invest blindly.
