Ronatec C2C makes as well as distributes multiple blacking chemicals for all types of metals. With new and innovative formulations created each year, we are able to stay on top of the market with the most up to date antiquing & black oxide products.
If you look around at items used in our everyday lives, most often you will come across steel or stainless steel components that have a black appearance. A portion of these black finishes you will find are produced from black oxide process baths.
A black oxide process bath produces non-dimensional, conversion type coating on the surface of the part. For steel alloys, the complex can be either a copper-selenium complex or a magnetite coating depending on the process bath used. For stainless steel alloys, the most common process bath used is an elevated temperature, caustic soda sodium nitrate process bath. This process bath will produce a magnetite complex resulting in a black finish on stainless steel.
Black oxide finishes on steel alloys, while providing an attractive black color, will not provide any corrosion resistance. These finishes must be treated with some type of post treatment so that the part will not corrode in the environment. The post treatment technologies can be petroleum based oils, water soluble or synthetic, and waxes. For a listing of post treatments available, please see our Post Treatment section.

ENE BLACK IMMERSION D 6
This composition formulated to produce colored finishes on copper based alloys by simple immersion at room temperature. By varying the operating concentration of the is a concentrated, mildly acidic non-sulfide containing liquidENE®BLACK IMMERSION D 6and by varying the immersion time, a range of color tones from light brown to brown and to black can be obtained. The finish produced in the ENE®BLACK IMMERSION D 6 with steel wool, scratch brushing, lea wheeling or by other mechanical means to produce a variety of “highlighted” or “antiqued” finishes. Coloring with a soft wheel of burnishing the parts in sawdust, corn meal or wood shells may allow for the production of uniformly toned finish. Application of the lacquer or oil coating on the finish will deepen and enhance the tones produced with the can be readily relievedENE®BLACK IMMERSION D 6 system.
