What Is Anodizing? Anodizing is an electrochemical technique that involves coating the surface of a metal in a decorative anodic oxide finish. This finish is achieved by changing the surface of the metal. The anodic oxide structure consists of a layer of aluminium oxide that has been produced on the surface of the aluminium. This layer makes up the anodic oxide structure. Because of this, there is a very slight increase in the overall thickness of the metal.

Aluminum oxide does not attach to the surface in the same way as paint or plating does. This makes it impossible to use any of those methods. The fact that it is fully bonded with the aluminium substrate that lies underneath it makes it resistant to chipping and flaking. As a result of the porous nature of its structure, it lends itself well to a wide range of secondary treatments, such as colouring and sealing.

The process of anodizing aluminium begins with the metal being immersed in a solution of acidic electrolyte, which is followed by the application of an electric current to the metal. The interior of the anodizing tank is outfitted with a cathode, and the aluminium itself functions as the anode during the process. This arrangement makes it possible for oxygen ions to be released from the electrolyte and mix with atoms of aluminium that are already present on the surface of the component that is being anodized. In practise, anodizing is nothing more than a form of oxidation that is subject to extremely precise control.

It is not a simple process to learn due to the fact that you want specialised expertise in addition to a specific quality of metal in order to acquire the result that you want, but once you do, you will be glad that you did it! Because of this, a substantial number of manufacturers avoid utilising this process and instead only offer plated finishes; this is the case despite the fact that the number of finishes that can be obtained using this method is significantly decreased.

At Hjyhardware, we have the benefit of many years of experience on our side, which enables us to harness the craft and apply it to our lighting line. As a result of this advantage, we are able to apply it to our lighting line. As a direct result of this, we are able to provide you with the highest-quality products that are currently available.

Let check out What Are The Advantages Of anodizing?

  • Because anodizing is a part of the aluminium, it enables total bonding and unparalleled adhesion. Durability: The vast majority of anodized parts do not experience any wear as a result of handling, installation, usage, or maintenance. Adherence: Because anodizing is a part of the aluminium, it enables total bonding.
  • Parts that have been color-anodized maintain their good colour stability even when they are exposed to ultraviolet radiation; they do not have an applied coating that is prone to chipping or peeling; and the colouring procedure can be performed multiple times on the same part.
  • The anodizing process does not leave any marks on the components, which ensures that the finish will be of the same high quality as it was when it was first applied.
  • When it comes to upkeep, an anodized profile normally only requires a quick washing with some soap and water to be restored to its original beauty.
  • Extruded aluminium can be anodized to provide a wide range of sheens and colours, but the intrinsic metallic sheen of the material is not obscured by the process. This contributes to the overall aesthetic quality of the material.
  • When compared to other methods of finishing, anodizing offers a very cost-effective value, especially in terms of the cost. The longevity of the product, in addition to the minimal costs associated with its production and maintenance, contributes to the product’s replacement costs being kept to a minimum.
  • The fact that anodizing is one of the industrial processes that is least harmful to human health and has the lowest impact on the environment makes it a strong candidate for compliance with the most recent environmental regulations. In addition to this, it is one of the safest techniques that can be followed by workers as well as members of the general public. 
  • An anodized surface has a non-toxic composition, is chemically stable, will not decay, and can tolerate heat up to the point where aluminium will melt. Additionally, it will not degrade over time. Because the anodizing process is nothing more than the continuation of a naturally occurring oxide reaction, it is perfectly safe and does not result in the development of any potentially harmful by-products. 
  • This is one of the reasons why the anodizing process is so widely used. The chemical baths that are used in the anodizing process are often reclaimed, recycled, and reused as part of standard operating procedure.
