Bright Dip

Overview

Bright dip is a chemical polishing process that brightens and enables bold coloring of aluminum primarily for cosmetic applications. This is accomplished by leveling the microscopic roughness of the aluminum surface and increasing its specularity, leaving no deposits on the surface of the part and protecting the anodized product from metal corrosion, fading and scratching.

The solution used for bright dip is a mixture of phosphoric and nitric acids, that requires frequent chemical analysis to keep the proper operating range.

Bright dip anodized products can be clear or dyed in a wide variety of colors. Some industries that use the bright dip process to enhance their products are the aftermarket automotive parts, light reflectors and frames, appliances, architectural trims, safety and recreational goods, sporting goods, and industrial and military products.
