Nickel 200 Machinability

The alloy can be easily worked and fabricated using any machining technique. Its characteristics make it easier to machine than other nickel alloys. Nickel alloy 200 has low work hardening rate. Work hardening occurs when a metal becomes harder and less malleable as it is deformed during machining. 

However, Nickel 200 resists work hardening, allowing it to be machined with ease and reducing the risk of tool wear. Another factor contributing to its machinability is its high ductility. Ductility refers to a material’s ability to undergo plastic deformation without fracturing. Nickel 200 can be stretched, bent, or shaped without breaking, making it suitable for various machining processes.

In addition, 200 Nickel alloy easily dissipates heat generated during machining, reducing the risk of overheating and maintaining dimensional stability. The combination of low work hardening, high ductility, and good thermal conductivity makes Nickel 200 suitable for machining operations such as turning, milling, drilling, and tapping.

Nickel 200 Magnetic Permeability

Magnetic permeability measures a material’s ability to establish and sustain a magnetic field. At room temperature, Nickel 200 displays ferromagnetic behavior, which can be magnetized and retain its magnetism. This characteristic makes it useful in applications requiring magnetic properties, such as magnetic shielding and storage devices.

Nickel 200 Magnetic Permeability

Nickel 200’s high magnetic permeability allows it to effectively redirect and absorb magnetic fields. This creates shields or barriers to protect sensitive electronic components from external magnetic interference. It can be used in electronic devices, scientific instruments, and even telecommunications to shield equipment from unwanted magnetic influences.

However, Nickel 200 magnetic permeability can be affected by temperature, stress, and composition. Nickel 200 undergoes a transition at elevated temperatures and loses its ferromagnetic properties, becoming paramagnetic instead. This transition is known as the Curie temperature, and for Nickel 200, it occurs at approximately 358°C (676°F).

1. Nickel 200 Vs Nickel 201

When comparing Nickel 200 vs. Nickel 201; the first is best for applications with resistance to deformation and high mechanical strength as a strict condition, such as aircraft components, and power distribution. 

On the other hand, Nickel 201, is particularly suitable for applications involving strong reducing agents, such as sulfuric acid, hydrochloric acid, and alkaline salt solutions, due to its 0.02 percentage of carbon.

2. Nickel 200 Vs 205

The presence of copper in Nickel 205 enhances its resistance to deformation in certain environments, particularly in reducing acids. On the other hand, Nickel 200 does not easily lose electrons to oxygen, hence its application in workspaces concerned about corrosion.

3. Nickel 200 Vs 718

Nickel 718 is a precipitation-hardening alloy metal. Nickel 200 and Nickel 718 have different mechanical properties and applications. Nickel 200 is resistant to oxide formation and is a good thermal energy conductor.

On the flip side, it is commonly used in demanding applications that require high strength and resistance to extreme environments, such as gas turbines, jet engines, and oil and gas industry components.

Nickel 200 Weldability

The low carbon content of this alloy reduces the risk of carbide precipitation and sensitization during welding, which can cause the alloy to become susceptible to corrosion and reduce mechanical properties. This makes Nickel 200 less prone to weld-related issues and ensures the integrity of the welded joints. 

Welding Nickel 200 to Carbon Steel

Manufacturers who want to control their welding process normally incorporate the tungsten inert gas method.  On the flip side, MIG welding uses a consumable wire electrode and an inert gas shield to protect the weld pool during the process. It offers higher deposition rates than TIG welding and is commonly used for larger and thicker weldments. 

Welding Nickel 200 to Carbon Steel

You can weld Nickel 200 to carbon steel. However, certain challenges may be incurred, and some factors must be addressed to ensure a successful and reliable weld. One challenge when welding Nickel 200 to carbon steel is the difference in their thermal expansion coefficients, Nickel 200 has a lower co. of thermal expansion. 

Therefore, they will expand and contrast different rates, which isn’t much of a problem. It can only lead to residual stresses and potential cracking of the fabrication interface. To mitigate this, you must use proper joint design, preheat them, and carry out an intricate post-weld heat treatment.

When welding Nickel 200 to carbon steel, it is common practice to use intermediate filler materials to bridge the gap between the two dissimilar base metals. These filler materials, often nickel-based alloys, help to accommodate the differences in thermal expansion, provide a compatible weld pool, and enhance the mechanical properties of the joint. 

Another crucial part of this process is deciding what welding technique will achieve the desired result. It is common to use TIG or MIG (metal inert gas) welding with appropriate shielding gases. 

These methods provide precise control over the welding process and allow for the adjustment of parameters to accommodate dissimilar base materials. Pre-weld and post-weld cleaning processes, such as mechanical cleaning, solvent cleaning, or wire brushing, are also necessary to ensure proper fusion and improve the weld quality.


1. What Is Nickel 200 Price?

The Nickel 200 price varies depending on the manufacturer, location, customization options, and other factors. However, the Nickel 200 material sells for an average of $35-$80 per kg. Also, remember that the product, wire, flanges, bars, plates, or sheet will also determine the price of the Nickel 200 material.

2. What Is the Recommended Annealing Temperature for Nickel 200?

For Nickel 200, the recommended annealing temperature is between 705°C to 875°C. This ensures that the material reaches its critical temperature, restoring its grain structure and eliminating any work-hardening effects or other defects that may have occurred during fabrication or use.

Annealing Nickel 200 or other materials refers to the fabrication process where the alloy is subject to heating and cooling rounds to improve its mechanical properties. During this process, the Nickel 200 material is heated to the target temperature and held there for a long time to allow the desired changes to occur. 

After the annealing, Nickel 200 is slowly cooled to room temperature to avoid any rapid temperature changes that could induce additional stresses or cause distortion. This slow cooling process is often called “furnace cooling” and ensures the material retains its desired properties.

Applications and Industries

Nickel 200 is used to manufacture electronic parts (high-power infrared emitters and radio valves) electrical components (battery connections, and terminals) heating element wirings, welding consumables, and more.

This alloy also serves the food processing industry, aerospace, chemical industry, missile components, synthetic fiber processing, and more.
