Benefits of Nitric Passivation
AMS 2700, AMS-QQ-P-35, ASTM A967
Nitric passivation refers to a process in which a metal surface, particularly stainless steel, is treated with a nitric acid solution to remove contaminants and promote the formation of a protective oxide layer. This oxide layer enhances the corrosion resistance of the metal and offers several benefits. Paramount Metal Finishing offers nitric passivation of large and small parts to the following specifications AMS 2700, AMS-QQ-P-35 and ASTM A967.
Here are some of the key benefits of nitric passivation:

Anodize is an oxide coating that is a highly effective corrosion protection for aluminum alloys and cast aluminum alloys. Anodizing is an excellent bonding base for paint, powder, and adhesives. The oxide is a hard electrically dielectric coating that can be dyed to different colors for decorative and none decorative purposes. Hard coat anodizing often referred to as MIL-PRF-8625 Type III is a thicker coating with a high degree of abrasion resistance. Types II and III are the most common types of anodizing.
MIL-PRF-8625 is the military specification that applies to anodizing aluminum. It has several types and two classes. Paramount Metal Finishing applies two types of MIL-A-8625 and two classes. Paramount Metal Finishing applies MIL-A-8625 Type II and Type III with class l and ll. Class I is the natural color that comes from anodizing the alloy. The natural colors span from clear, grey, olive green and black and are determined by several factors such as the alloy, process parameters and coating thickness. Class II relates to a dying process that can produce a wide spectrum of colors by soaking in a dye solution prior to sealing the surface.
Anodizing capabilities applied by Paramount Metal Finishing:
Note: MIL-PRF-8625 replaces MIL-A-8625. Both are still commonly used on drawings.

MIL-DTL-5541 chemical film is a conversion coating to stop aluminum from oxidizing. It is an excellent pretreatment for primer and paints to adhere to. Chemical film increases corrosion protection and adhesion on machinable aluminum alloys and aluminum casting alloys. Chemical film is a cost effective solution for corrosion and a paint base that in many cases eliminates the need for a primer or topcoats such as wet paint or powder coating. It is also used as an adhesion enhancing coating for bonding with adhesives and form in place gaskets.
There are 2 Types of MIL-DTL-5541 and two classes:
MIL-C-5541 is similar to MIL-DTL-5541 in Type and Class with the exception that MIL-C-5541 is always a hexavalent chromium coating. Other similar chemical film specifications are MIL-DTL-81706, ASTM B449, ASTM B921, AMS 2473 and AMS 2474.
