Nickel alloy tubes mainly have the following applications:
Monel400 is a corrosion-resistant alloy with the largest amount, the most versatile and excellent comprehensive performance. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas media, and also has excellent corrosion resistance to hot concentrated lye. At the same time, it is resistant to corrosion from neutral solutions, water, seawater, air, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracks and has good cutting performance.

Nickel alloys can be used as materials for electronic tubes, precision alloys (magnetic alloys, precision resistance alloys, electric heating alloys, etc.), nickel-based high-temperature alloys, nickel-based corrosion-resistant alloys, and shape memory alloys. Nickel alloys are widely used in energy development, chemical industry, electronics, navigation, aviation, aerospace and other sectors.

A heavy nonferrous metal material based on nickel and composed of other alloying elements. In order to further improve the physical and chemical properties of nickel and meet the requirements of scientific and technological and industrial development, it is necessary to add an appropriate amount of alloying elements to nickel.

Nickel alloy ingots or castings are mainly produced by vacuum melting and casting. The ingots are first hot rolled, extruded or forged, then rolled or stretched after intermediate heat treatment, and finally processed into the desired finished product. Some nickel-based high-temperature alloys are directly cast or made into the required parts by powder metallurgy.

Nickel-based wear-resistant alloy. The main alloying elements are chromium, molybdenum, tungsten, and also contain a small amount of niobium, tantalum and indium. In addition to wear resistance, it also has good oxidation resistance, corrosion resistance and welding properties. It can be used to manufacture wear-resistant parts, and can also be used as a coating material, which can be coated on the surface of other base materials through surfacing and spraying processes.

Trace elements are added to the alloy to eliminate the adverse effects of harmful impurities on the alloy properties, to give the alloy some special physical properties, or to strengthen the alloy grain boundaries, thereby ensuring that the alloy products have better use effects and longer service life.

Nickel alloys can be used in the following industries:
1. Calcination furnaces. For example, they are used to calcine and produce high-performance corundum, calcine chromite to produce ferrochrome, and recover nickel used as a catalyst in petrochemicals.
2. Chemical and petrochemical industries, using them to prepare new steam cracking crude gasoline furnaces to produce hydrogen, etc.
3. Automation devices. Such as catalytic support systems and spark plugs.
