Anodising is an electrochemical process that helps to improve the surface properties of a metal, to make it look better, last longer or resist corrosion. Not all metals can be anodised, but the following can:
Aluminium
This is the most commonly chosen metal for anodising as it reacts very well to the surface treatment to make a strong layer of protective oxides that make it harder to scratch. Anodising treatments from companies like //www.poeton.co.uk/surface-treatments/anodising/ also allow colour finishes like red, black, blue or clear for vibrant or high shine finishes.
Titanium
Anodising on titanium creates naturally occurring colours by adjusting the oxide layer’s thickness. This can result in fantastic bright blues, purples and golds just by changing the surface. These surfaces, which are also corrosion resistant, are used heavily in jewellery, medical tools, aerospace and high-performance purposes.
Magnesium
Magnesium is incredibly light, so it’s great for cars and aircraft. However, it is prone to corrosion. Anodising makes it more resistant to moisture and wear. It is commonly used in drones, electronics and medical devices.
Niobium and Zirconium
Like titanium, niobium and zirconium are anodised to create natural and bright colours without needing any dye. They’re usually used to make decorative items in jewellery or special inserts in medical devices. The layers are biocompatible.
Copper
Copper is harder to anodise, but it can be, with a thin decorative layer or special electronics where the focus is on the visual finish, not durability.
As you can see, anodising can be used in many ways to achieve functional and aesthetic benefits.
