The chemical polishing of aluminum, also known as “Bright Dip,” is widely used to produce specular finishes on aluminum alloys for various modern applications. This method is gaining popularity because of its low-cost method of increasing the value of aluminum products. The finish is comparable to the luster normally obtained by electropolishing, and bright dipped aluminum is replacing many electro-polished or electro-plated parts for specialty items such as automotive trims, picture frames, cosmetic containers, and many others.

​

Fang Chemicals has developed two proprietary formulations for the polishing of aluminum and aluminum alloys: 80FC and Fangbrite 15.  Both formulations have been successfully used in the bright dip anodizing industry.​

 

• Polishing Solution 80FC is a light greenish solution with specific gravity at 1.64 (60 F) minimum.  It is formulated with high quality PPA plus fume suppressant and copper additives.

• Fangbrite 15 is a greenish solution with an improved formulation based on 80FC.  It contains high quality PPA plus sulfuric acid, fume suppressant, and copper additives. We provide Fangbrite 15 with 4 different specific gravities: 1.70, 1.72, 1.74 and 1.76 (60 F).

 

Fang Brite Dip, a subsidiary of Fang Phos, has been created in 2026 to focus on our mission of providing the best products and services within the aluminum anodizing market.
