Anodized Aluminum Anodized aluminum has undergone an electrolytic process in order to gain increased corrosion and wear-resistance, amongst many other benefits, due to the high susceptibility of untreated aluminum alloys to corrosion. Anodized aluminum products are important throughout industry and commerce.

What is Anodized Aluminum?

Anodized aluminum is, simply, aluminum that has undergone a process to create a highly-durable finish. To create anodized aluminum, the metal is immersed in a series of tanks where it undergoes an electrochemical process and an anodic layer is grown from the metal itself. Due to the fact that this anodized layer is created from the aluminum itself, rather than being painted on or applied, this anodized aluminum will never chip, flake, or peel, and, compared to other similar materials on the market, it is significantly more durable. In comparison to other metals like copper and stainless steel, anodized aluminum is 60% lighter and three times tougher than the raw material.

What Makes Anodized-Aluminum Coil Unique?

During the coil anodized-aluminum process, unwound coils of raw aluminum are pulled through a series of tanks where they are cleaned, colored, anodized, sealed, and then wound back up again. Anodized coil aluminum of the highest quality is created after this process is complete; it is strong, adaptable, and offers consistent color matching in accordance with the specific requirements of clients. Since the anodized metal is rolled, it is already prepared for transport.

A number of steps from the more-conventional, batch aluminum-anodizing process that increase costs and result in inconsistent finishes are removed in the coil anodized-aluminum process. An electrical contact point must be made during the batch aluminum-anodizing process in order for the electrical current to help the anodic layer expand. This is accomplished by fastening each item to be anodized with a metal hook, or rack, which frequently leaves burn marks on the material that must be trimmed off, increasing waste and cost.

What are the Benefits of Anodized Aluminum?

Durability

Aluminum is already a tough substance, but after the anodization procedure, the surface gets even stronger than the original aluminum. Once anodized, this material develops a surface that is three times tougher than regular aluminum and will not chip, flake, or peel, even after being colored. This product won't ever rust, tarnish, or weather because the anodization process is controlled by aluminum oxidation. Anodized aluminum is one of the strongest and most useful metal goods on the market.

Custom Color Options

Due to the open pore structure of the anodic layer before sealing, anodized aluminum can be processed to match almost any brand color or Pantone® swatch. Due to anodized aluminum’s adaptability, it can also be manufactured to mimic the appearance of other metals such as gold, bronze, copper, stainless steel, brass, and more without the worry of deterioration from the elements. There are various weathered-appearance finish options to pick from, though, if a worn-in appearance is required. Again, due to the properties of anodized aluminum, the color selected will not chip, peel, or flake over the course of the product's lifespan. Additionally, the UV-stable colors generated are guaranteed to last a long time.

Light in Weight

A lightweight metal, anodized aluminum weighs around 60% less than stainless steel, copper, or brass. This greatly reduces the cost of shipping this material that can be employed to address a variety of design problems. Anodized aluminum provides a flexible alternative whenever a light, strong, and appealing material is required, from architecture to consumer product design.

Where is Anodized Aluminum Used?

Any application that currently uses another metal material can use anodized aluminum. Manufactured anodized aluminum serves the following sectors:

Architecture

SInce aluminum does not rust, anodized aluminum is used for a variety of outdoor purposes like the framework for outdoor furniture, roofing systems, and storefront exteriors. It also provides an interesting exterior option for stunning, contemporary building rusts, patinas, or weathered effects. Anodized aluminum is a beautiful, lightweight, and cost-effective solution for interior finishes like ceiling panels, retail signage, and elevator panels because it can be manufactured to order in any color, finish, or texture.

Transportation

Aluminum that has been anodized is three times as durable as aluminum that has not been anodized. Anodized aluminum gives the durability and weather resistance vehicles need, as well as the great elegance customers demand. This is true of the interiors of commercial aircraft, rail car panels, and the brilliant, external trim of sports automobiles.

Consumer Goods

Customers seek out durable goods that are aesthetically pleasing and fit their way of life. Any appearance, texture, or color can be achieved with anodized aluminum. Anodized aluminum gives the adaptability and quality that your customers want in microwaves, coffee makers, and other consumer goods. Anodized aluminum can be a stunning component of any project or product, whether you're making eye-catching skyscrapers and structures, artwork, the newest line of luxury vehicles, or high-end appliances. The environmentally-friendly anodizing technique results in a finished material with unmatched and dynamic beauty, longevity, and durability.
