Anodizing is a process which includes metal finishing given to the material which uses oxidation to change the surface into a ceramic state from a metallic. It is generally being used when the plating of aluminum done, anodizing is also well-matched with various other nonferrous metals like magnesium,  titanium, stainless steel, copper alloys, zinc and more.

  1. Definition of Steel

Steel is derived from the alloy of iron and various other elements. Steel are of four types. They are carbon steel (it is an alloy of carbon and iron), the other is alloy steel (it contains the alloying elements which doesn’t have carbon, such as copper, silicon, titanium, manganese, aluminum), the tool steel (is has high hardness), stainless steel (it is corrosion resistant steel).

The Anodized aluminum is used as:

  • Safeguarding the satellites in the space.
  • Increasing the life of the roofs, ceilings, and walls.
  • Making up computer hardware and household appliances.
  • Gives a new look to the appliances.
  • Enables more life for the component.
  1. Advantages of Anodizing

Anodized finishing gives a lot of benefits which includes:

  • Improved resistance next to the negative forces of corrosion.
  • Better resistance towards the wear and tear which occurs while using the metal.
  • Creating a harder, stronger, and better surface for the metallic.
  • Making a good appealing finish.
  • Making the brighter and more lasting color of the finish.

Anodizing the metal – the following steps are followed:

  • The first thing you have to do is turn on the power. Don’t increase the power too much as it can burn the metal.
  • Oxidation will start to keep the power supply regular.
  • As the anodizing process takes place to mix it with dye.
  • After 45mins switch off the power. You should wear protective gloves.
  • Now put the metal in the dye bath.
  • Put the boiling water on the plate.
  • Now just remove the metal.

The plating can be done on various types of materials and on different components, which also includes steel. The various parts which are made up of steel and the different grades of steel which has to be plated? This article will help you to know about plating on steel which will help you take the decision in your organization.

  1. Anodizing Process of Steel

Plating on steel is done in a similar way as on other materials.

  • The moment you start electroplating the steel, it should be cleaned.
  • Then put it in an electrolytic solution where it is being introduced with the plating material.
  • Switch on the electricity.
  • The engineer will fix it to rack the steel which is electroplating.
  • Thereafter being introduced to an electrolytic solution.
  • Then place it inside a closed barrel along with the solution.

Steel is a part of electroless plating. Here the steel is put inside an aqueous solution and chemically the engineer will put the plating material over the steel, with no an outer electrical power source which can induce the reaction.

  1. Aluminum is Having a Great Business

Every day we come in contact with so many sources which are made up of aluminum.

  • It is a soft, durable and a  light weighted metal which is found everywhere be in aircraft or any vehicle parts and even you can find it in components to food, windows, doors and foil wrap and much more.
  • The report by Aluminum Association, says that the aluminum’s straight economic impact counts to be more than $75 billion per year.
  • If taking into consideration all the aluminum-related industries it goes by $186 billion which is a huge number.
  1. How to do Plating on Aluminum

Many manufacturing Industries feel it important to put an additional coating over an aluminum part for the reason of improving the corrosion protection, giving more resistance towards wear or sometimes even improving the look of the product.

  • Electroplating is the method which is used.
  • This process starts with immersing the aluminum components inside the electrolytic solution.
  • Then putting up an electric current so that the dissolved ions will be deposited of the other metal over the surface.
  • Another option is electroless plating, where there is no need for electricity. Rather deposition takes place through an autocatalytic reaction.


  • Anodizing is best for metals.
  • You should follow the methods to safeguard the metals.
  • It increases the lifespan of the metal.

The metals are great in demand in the market thus require proper care.

Can you anodize any metal?

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized.

Can I anodize aluminum at home?

Anodizing works particularly well with aluminum, so, if careful, you can do it at home. You can find small aluminum parts for this purpose relatively affordably from most home improvement stores, as well as online. During this process, the part that you are anodizing will function as your anode.

How do you anodize steel?

What materials can you anodize?

What Metals Can Be Anodized?
  • Aluminum. Aluminum and aluminum alloys are the most commonly anodized materials.
  • Magnesium. The most common purpose for anodizing magnesium is as a paint primer, with thin films (as little as 5 μm) being sufficient for this use.
  • Titanium. Anodized titanium is commonly used in dental and orthopedic implants.

Can you hard anodize steel?

The oxide layer that forms on iron or carbon steel is commonly known as rust, which readily flakes off and actually promotes the corrosion of the underlying material. So an anodising process for steel would not be terribly useful.

Can I anodize stainless steel?

Stainless steel cannot be anodized in the true sense of the word unless a hot caustic solution is used. There are, however, a few alternative ways to achieve some similarish results to anodizing, like what you would expect with titanium and aluminum.

What colors can you anodize steel?

adv. Yes, we can anodize stainless steel to different colors, including black. However in comparison to titanium anodizing, stainless steel colors are not so durable and require some type of protective coating to become durable. A.

Can stainless steel turn black?

The act of turning stainless steel black is called “bluing.” Bluing chemicals used to require a heat source to work. Because heating these chemicals was bad for the environment, new chemicals have been developed to turn stainless steel black or brown.

What is the color code for stainless steel?

What does metallic look like?

A metallic color is a color that appears to be that of a polished metal. The visual sensation usually associated with metals is its metallic shine. This cannot be reproduced by a simple solid color, because the shiny effect is due to the material’s brightness varying with the surface angle to the light source.
