Are you curious about surface finishing options for your aluminium products? Look no further than aluminium anodizing! It is a process of surface finishing that puts a layer of aluminium oxide on the surface of an aluminium substrate. The importance of aluminium anodising is to prolong the lifespan of aluminium products, enhance their corrosion resistance, prevent scratches and wear, and improve their visual aesthetics. During the process, the product to be coated functions as an anode in an electrolytic cell.
Advantages of Aluminium Anodizing
- Aesthetically pleasing
Anodising preserves the inherent metallic gleam of aluminium. In addition, optimal surface coverage can be guaranteed as an immersion process. Unlike other finishing processes, some non-visible surfaces are not coated. Most metal forms and textured surfaces, such as perforated sheets and mesh material can obtain a highly consistent and regular finish through aluminium anodizing. - High corrosion and wear resistance
Anodising forms a strong, wear-resistant coating layer that sufficiently protects the underlying aluminium. In fact, neither aluminium nor anodized aluminium will rust easily. However, there is still a possibility when they are exposed to high humidity, moisture or corrosive environments. Therefore, anodized aluminium is way more resistant when there is a thicker layer of oxide protecting the aluminium. This, in turn, benefits aluminium’s durability, making it an incredibly robust material in the construction industry. - Ease of maintenance
Aluminium anodizing has many benefits beyond surface finishing. Unlike other operations like fabrication and installation, anodizing doesn’t leave scars or unexpected wear on products. It’s also easy to clean with just a damp cloth or mild acid cleansers. Plus, the oxide layer is integral with the metal itself, so it won’t peel or crack like ordinary coatings. This makes anodized aluminium very low maintenance.
Summary
Other than wet spray painting, aluminium anodizing is another option for surface finishing that you may want to consider. This innovative process adds a layer of aluminium oxide to your aluminium substrate, resulting in a stunning, long-lasting finish that’s both aesthetically pleasing and highly durable.
