What is Bright dipping anodizing and its production process?

What is bright dipping anodizing?

Bright dip anodizing is a process where aluminum is chemically polished to bring out more brightness and bold colors in cosmetics applications.

It also will help protect the aluminum against scratching, fading and corrosion.

Chemical polishing of aluminum, often by treatment with a mixture of nitric acid and phosphoric acid, yields a mirror-shiny (specular), highly reflective surface.

It is almost always followed by anodizing to protect the surface and provide some choice of colors.

Bright dipping anodizing involves two consecutive finishing processes:

The first one is bright dipping, which gives your extrusions a bright specular (or mirror) finish.

The second process, anodizing, adds extra corrosion protection.

Aluminum profiles are bright dipped, which means they’re bathed in a solution of phosphoric and nitric acid.

This smoothes out the microscopic, rough peaks and valleys on the aluminum surface and makes it very shiny.

After bright dipping, the extrusions are anodized

Anodization is a process that thickens the aluminum’s naturally occurring oxide layer.

This layer protects the aluminum from corrosion. The anodized extrusions will have added corrosion resistance.

The enhanced oxide layer has lots of tiny pores on its surface, which makes it ideal for dying.

Different colored dyes can go into those tiny pores before the oxide layer gets sealed. Once it’s sealed, the color is locked in and it is extremely resistant to fading.

Bright dipped anodized aluminum profiles features will be the following:

It will be a very shiny and mirror-like look;

Will be corrosion resistant;

Can be dyed in different colors

Bright dipping provides a very shiny, mirror-like look for aluminum extrusion.

Bright Dip anodizing enhances the glossy appearance of aluminum for cosmetic applications and achieves a highly reflective surface finish similar to mechanical polishing, but more than mechanical polishing.
