Browning stains for the brassing of brass, copper and bronze are used in model building as well as in many other areas in order to obtain anthracite to black metal surfaces depending on the duration of exposure and metal type. Furthermore, the metal is given a slight corrosion protection by browning Oiling can be significantly improved.
Due to the small thickness of the black oxide layer of approx. 1 μm, the workpiece remains extremely dimensionally stable. Nevertheless, this layer is extremely abrasion and flexed and can withstand temperatures up to 300 ° C. The pickling process is therefore ideally suited for technical modeling. Especially in this area, metals such as brass, copper and bronze are treated with bronze pickling to achieve an antique appearance of the workpiece. As a result, the pickling is also suitable for browning flue gas emitters. After the browning, you can paint, treat or grease the treated parts without problems.
In the case of the non-ferrous metal baler Balistol Nerofor offered by us, the workpiece does not need to be heated before application. You only have to degrease the workpieces with acetone and hang them in the Brünierbeize.
Nerofor Black Stain is suitable for the following applications:
- To preserve an antique look by pickling
- To color the work piece a dark one
- To make a component indispensable against corrosion
