In nature, the main metal nickel ore is red metal nickel ore and austenitic metal nickel ore. Cuba is the most famous country in the world for depositing nickel ore. There are also a large number of metallic nickel deposits in Dominica.

The use of metallic nickel is manifested in the electroplating industry. Nickel-plated metallic articles are beautiful, clean, and not easily rusted. Very fine metallic nickel powder is often used as a catalyst in the chemical industry.
Nickel metal is used in large quantities to make alloys. Adding metallic nickel to steel can increase the mechanical strength. Metal nickel steel is used to make parts of the machine subjected to high pressure, shock and reciprocating loads, such as turbine blades, crankshafts, connecting rods, etc. Nickel metal containing 36% nickel, carbon 0.3-0.5% of the nickel steel, its expansion coefficient is very small, almost no thermal expansion and contraction, used to create a variety of precision machinery, precision gauges and so on. High-metal nickel steel containing 46% metallic nickel and 0.15% carbon is called "platinum-like" because its expansion coefficient is similar to that of platinum and glass. Such high metallic nickel steel can be welded into glass. It is very important in the production of light bulbs and can be used as a substitute for platinum wire. Some precision lens frames are also made of this type of platinum steel, and the lens does not fall out of the box due to thermal expansion and contraction. An alloy composed of 67.5% metallic nickel, 16% iron, 15% chromium, and 1.5% manganese has a large electrical resistance and is used to make various varistors and electric heaters.
In addition, metallic nickel is magnetic and can be attracted by magnets. Alloys made of aluminum, cobalt, and metallic nickel are more magnetic. When this alloy is attracted by an electromagnet, it will not only be sucked by itself, but also hangs something 60 times heavier than it will not fall off. In this way, it can be used to make electromagnetic cranes
