Finishes You Can Depend On

An alternative to caustic etching, acid etching uses fluoride-based ions to modify the surface of aluminum. This method creates a finished product that has a more consistent matte finish and offers better corrosion resistance. Additionally, because this process produces less waste, it is the more environmentally-friendly etching option.

Also called two step or two stage colouring, anodized aluminum parts are immersed in an electrolyte bath. This electrolyte bath contains metal salts which are deposited into the coating.  An electrical current is then passed through the solution which causes the metal salts to change from a champagne-coloured finish to standard bronze, all the way through to black – and everything in between.

Following the electrolytic colouring process, the resulting oxide layer is corrosion resistant and is extremely hard; it will not chip, flake or peel, providing the utmost in durability. Due to these properties, anodizing continues to be a popular finishing choice for a range of applications including architectural and marine products, office furniture, lighting, electronics – and more.
