Nickel200/N02200/Ni200/N6 Tube Bar Rod Sheet/ Strip
Overview
Nickel 200, also known as N6, is a solid solution strengthened pure nickel alloy consisting primarily of 99.5% pure nickel, one of the first metals to be discovered and used in human history. Its low carbon content (less than 0.15%) gives it good mechanical properties and high temperature oxidation resistance. Nickel content in Nickel 200 accounts for about 63% of the entire alloy and is the main element constituting the alloy. In addition, the alloy also contains a small amount of iron to increase strength and hardness, while the addition of chromium and molybdenum elements improve the corrosion resistance and high temperature strength, respectively.
Nickel 200 has a number of significant features and benefits. First of all, it shows excellent corrosion resistance, whether in a dry environment or in a variety of acidic, alkaline or salt solutions, showing excellent corrosion resistance. Especially in acidic environments, Nickel 200 can withstand the attack of strong acids such as nitric, sulfuric and hydrochloric acid. Second, Nickel 200 maintains stable mechanical properties and oxidation resistance at high temperatures, giving it high strength and heat resistance in the temperature range below 1000 ° C.
The physical properties of Nickel 200 are also excellent, with excellent ductility, weldability and fatigue resistance. At room temperature, Nickel 200 can be cold worked and stretched, and its weldability allows it to be joined by a variety of welding methods. Nickel 200 is also an important electrical and thermal conductive material with excellent thermal and electrical conductivity.
Because of these excellent properties, Nickel 200 is widely used in many fields. In the chemical industry, Nickel 200 is used to manufacture a wide range of corrosion-resistant equipment and components. In the energy and electronics industries, it is used to manufacture components such as battery airtight containers, vacuum tubes, magnetic parts, semiconductors, resistors and capacitors. Nickel 200 plays an important role in the aerospace industry, where it is used to make components for aircraft engines, such as turbine blades, as well as structures and fuel rods for ships..

Corrosion Resistance
Pure nickel has good corrosion resistance, which makes it widely used in aviation, chemical, Marine and nuclear industries, which is a major advantage of its use as a metal material. Pure nickel is particularly resistant to alkali corrosion, whether at high temperature or molten alkali is relatively stable, therefore, pure nickel has been widely used in the alkali industry. At the same time, pure nickel also shows high stability at room temperature for seawater, salt solutions and organic media (such as fatty acids, phenols, alcohols, etc.).
Pure nickel is not resistant to inorganic acids, such as acetic acid and formic acid is unstable. However, please note that the corrosion resistance of pure nickel is not limited to these conditions, it has excellent corrosion resistance in most media, and its alkali corrosion resistance is second only to silver. The high strength and plasticity of pure nickel, as well as its excellent thermal stability and thermal strength at high temperatures (especially above 800 ° C), further enhance its application value in a variety of harsh corrosive environments.
The surface of pure nickel forms an extremely dense and strong protective film under open air conditions, further improving its corrosion resistance. This allows pure nickel to generally maintain a bright metallic luster in the indoor atmosphere, even in the outdoor atmosphere, ocean and rural atmosphere, its corrosion rate is relatively low.
