An introduction to matte and gloss anodising

When we think of surface finishes, we likely think of the slick coats of glossy paint on a sports car – but there’s so much more to the process than aesthetics alone.

For aluminium especially, anodising can host plenty of benefits beyond visual finesse. Depending on the intended use, the process can turn standard metals into sturdy and aesthetically sharp surfaces.

Matte anodising

Perhaps the most understated version, and highly functional, matte anodising provides the opposite of gloss anodising’s shiny surface, through its non-reflective coat. If you’re after glare reduction, or want a more subtly charming design, this is the choice for you.

You’ll see this approach most commonly used for consumer electronics, aerospace components, or architectural trim, where the functionality is prioritised over the form. That’s not to say they’re not aesthetic, rather, they prioritise efficiency.

The procedure consists of an etching on the aluminium’s surface, followed by the anodising process. The process is also perfect for reducing distractions – essential for, say, a control panel.

Gloss anodising

At the opposite end of the anodising spectrum, gloss produces the reflective, polished surfaces that really shine. The pre-treatment is a little different, using a mechanical polishing method or a bright dipping process to create a smoother surface for anodisation.

As mentioned earlier, these are the finishes you’d picture on a flashy sports car, but they’re also common on consumer products and electronics – anything that can benefit from an attractive, attention-grabbing appearance.

Added benefits and the choice to make

Anodised surfaces are often used to add additional strengths to the metal, such as durability, corrosion resistance, or wear resistance. Depending on your industry, you may want a greater focus on these aspects rather than aesthetics.

Regardless of the process you favour, providers will make sure to point you in the right direction, such as the experts at https://www.poeton.co.uk/surface-treatments/anodising. Strength or style, you’ll get the guidance you need.

Technical performance and a less conspicuous design would point towards a matte finish being your best choice. If aesthetic qualities are your main focus, nothing hits quite like a glossy, anodised finish.
