Professional export nickel products

Nickel can be used to make money, and on top of other metal plating to prevent rust.

Nickel process is found in 1751, the Swedish cronstadt, he used his copper nickel surface weathering grain together with hot charcoal, which made of nickel.

As a kind of metal elements, the density of nickel in the 8.9 g/cm3, melting point at 1455 degrees Celsius, the boiling point of 2730 degrees Celsius. The ionization energy is 7.635 electron volts. Material is hard, can have magnetic and good plasticity, protective film formed in air oxidation, protect and prevent continue to oxidation, nickel and alkali corrosion resistance at the same time, and can slow dissolve in the dilute acid. Due to nickel and doesn't react and nitric acid oxidation solution, so the nickel is often used as a reducing agent of moderate intensity.

With the gradual development of industry, the application of nickel is widely promoted.

Except for electroplating industry, let things beautiful, and to prevent rust, and be used as catalysts in chemical industry, nickel was used in the manufacture of alloy in larger amounts.

Add nickel to steel, for example, can improve the mechanical strength, nickel steel mainly in manufacturing and its impact under high pressure, and the load of parts, such as turbine blades, connecting rod or the crankshaft, and so on. By adjusting the ratio of nickel and carbon, I do not know can get the biggest play of nickel also to have the good effect to industry, such as nickel 36% and 0.3 0.5% carbon, the expansion coefficient is very small, can be used to manufacture a variety of precision machinery and gauge. Has a high nickel steel, known as the "platinum" its 0.15% carbon, nickel, 46% of the high nickel steel can be welded to the glass, for the great contribution on the bulb production.

In addition, it is worth mentioning a nickel alloy, nickel titanium alloy is, the material has the very strong "memory". Because it can remember its original shape, won "shape memory alloy," said. Its principle is because this kind of memory alloy has a characteristic of transition temperature, under and above the transition temperature and phase transition temperature and memory alloys have different organizational structure. Its structure, performance is also different. We often by adjusting the temperature, make it into the tools we need, and when finished by temperature, let it recover.
