STATIC OR BARREL TREATMENTS WITH OILING OR A DRY
This treatment is a black surface oxidation, used on ferrous metals with the sole exception of stainless steels. The color and finish depend on the type of salts and the preparation of the piece.
Burnishing is not a coating therefore it does not cover defects. As a result, if the item is scratched it will remain so even after the treatment. To obtain uniform burnishing, it is advisable to first sandblast the items.
To maintain it over time, the item must be oiled and stored in a dry place protected from atmospheric agents.
Our burnishing complies with DIN 50938 and MIL-C-13924.
