Nickel alloy:

An alloy of other elements is added based on nickel. About 30% of the Monel alloy containing copper, which was produced around 1905, is an earlier nickel alloy. Nickel has good mechanical, physical and chemical properties. Adding suitable elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve certain physical properties. Nickel alloys can be used as materials for electron tubes, precision alloys (magnetic alloys, precision resistance alloys, electrothermal alloys, etc.), nickel-based superalloys, nickel-based corrosion-resistant alloys, and shape memory alloys. Nickel alloys are used in a wide range of applications in the energy development, chemical, electronics, marine, aerospace and aerospace sectors.
Iron-nickel can be combined with copper, iron, manganese, chromium, silicon and magnesium. Among them, nickel-copper alloy is a famous Monel alloy. It has high strength and good plasticity. It has stable chemical properties in the atmosphere below 750 °C. Widely used in electrical industry, vacuum tube, chemical industry, medical equipment and marine shipbuilding industry.

Application and classification of nickel alloys:

1 Nickel based superalloy. The main alloying elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium and the like. Among them, chromium acts as an antioxidant and anti-corrosion, and other elements act as strengthening. It has high strength and resistance to oxidation and gas corrosion at 650~1000 °C. It is the most widely used alloy with high temperature strength and high temperature strength. The scarcity of talents in this area is mainly concentrated in the steel talent network. Used in the manufacture of high temperature components on aerospace engine blades and rocket engines, nuclear reactors, and energy conversion equipment.

2 nickel-based corrosion resistant alloy. The main alloying elements are copper, chromium and molybdenum. Has a good overall performance, resistant to a variety of acid corrosion and stress corrosion. The earliest application is nickel-copper alloy, also known as Monel alloy; in addition, nickel-chromium alloy, nickel-molybdenum alloy, nickel-chromium-molybdenum alloy and the like. Used in the manufacture of various corrosion resistant parts.

3 nickel-based wear-resistant alloy. The main alloying elements are chromium, molybdenum, tungsten, and also a small amount of antimony, bismuth and indium. In addition to its wear resistance, it is also resistant to oxidation, corrosion and welding. It can be used to manufacture wear-resistant parts or as a coating material, which can be coated on the surface of other base materials by surfacing and spraying processes.

4 nickel based precision alloy. Including nickel-based soft magnetic alloy, nickel-based precision resistance alloy and nickel-based electrothermal alloy. The most commonly used soft magnetic alloy is a permalloy containing about 80% nickel, which has a high maximum magnetic permeability and initial magnetic permeability and a low coercive force, and is an important core material in the electronics industry. The main alloying elements of nickel-based precision resistance alloys are chromium, aluminum, and copper. These alloys have high resistivity, low resistivity temperature coefficient, and good corrosion resistance for making resistors. Nickel-based electrothermal alloy is a nickel alloy containing 20% chromium. It has good oxidation and corrosion resistance and can be used for a long time at 1000~1100 °C.

5 nickel-based shape memory alloy. A nickel alloy containing 50% (at)% of titanium. Its recovery temperature is 70 ° C, shape memory

The effect is good. A small change in the proportion of nickel to titanium components can change the recovery temperature in the range of 30 to 100 °C. It is mostly used to manufacture self-expanding structural parts used in spacecraft, self-exciting fasteners for the aerospace industry, artificial heart motors used in biomedical applications, and the like.

can be applied to the following industries:

1. Heat treatment industry. Such as furnace rolls, bell furnaces and annealing furnaces.

2. Calciner. For example, it is used for calcination to produce high-performance corundum, calcined chromite ore to produce ferrochrome alloy, and to recover nickel used as a catalyst in petrochemical industry.

3. Chemical and petrochemical industries, using it to prepare a new steam cracking crude gasoline furnace to produce hydrogen.

4. Automation device. Such as catalytic support systems, spark plugs.

5. Nuclear industry cleaning equipment, such as nuclear waste removal.

6. Steel industry. Such as direct reduction of iron ore technology, the production of titanium sponge.
