What is Bright Dip Anodizing?

Bright Dip Anodizing is a process for enhancing the specularity or brightness of aluminum. This is achieved by leveling the microscopic imperfections or roughness on the surface of the aluminum. The degree of brightness is determined by the type of alloy in addition to the surface finish of the part. Bright Dip Anodizing is a chemical process that ultimately brightens aluminum without leaving any deposits on the finish.

There are numerous ideal bright dip aluminum alloys that are most suitable for bright dip anodizing. Typically, 5000 and 6000 series aluminums are capable of producing higher lusters compared to 2000 and 7000 series due to the fact that they are harder tempered.

The following aluminum alloys have proven to be most suitable for bright dip anodizing:

5357, 7016, 7029, 5457, 5557, 6063 & 6463
Thickness: .0001-.0007”
100-700 uin.
Max Part Size: 152” x 52” x 28”



What are the Benefits of Bright Dip Anodizing?

Bright dip anodizing is a Type 2 Anodize finish which enhances the glossy appearance of aluminum and provides pristine corrosion and wear resistance. The aluminum goes through the anodizing process as a pretreatment to prevent scratching or fading on the alloy while achieving a mirror like shine on your precision machined parts.



Why Does Aerospace Metals Stand Out?

While you may see many companies offering anodizing services – few companies are able to produce quality bright dip anodizing services due to the involvement of the complex process required. This process requires a solution of phosphoric-nitric acid operating at a minimum of 200 degrees Fahrenheit, which must be contained in a double walled type 316L SST tank. Ventilation is a key component in this process. The solution then releases substantial amounts of mustard-colored noxious nitric oxide from the bright dip tank as well as the rinse tank. Consequently, a garage type exhaust system is necessary for this part of the process. Nox fumes can be strenuous to scrub during bright dipping because they are soluble. Rocker type agitation is essential. Furthermore, there is a level of high skill required in racking and agitating the parts to ensure there are no spots where gasses may accumulate – which could potentially result in poor brightening.
