Forms a uniform thin anti-corrosion film! Since there is almost no dimensional change, it is suitable for high-precision parts.
"Black dyeing treatment" is a method that forms a black ferric oxide film on the surface of metals to prevent rust. It results in a black film with a metallic luster, giving it a beautiful appearance. A uniform thin rust-proof film is formed through chemical treatment, with a thickness of about 1μm, resulting in minimal dimensional changes, making it suitable for high-precision components such as precision machine parts, cutting tools, and other high-accuracy parts. Our company typically applies oil after black dyeing to protect the film. If you want to enhance the corrosion resistance of the black dye film, a "black dyeing + top coat" option is also available. 【Specifications】 ■Applicable materials: Iron, SUS ■Tank dimensions: H350×W450×D450 ■Processable size: H300×W350×D350 *For more details, please download the PDF or feel free to contact us.

basic information
Features of Black Oxidation Treatment ■ Product dimensions do not change significantly. ■ Unlike plating or painting, it does not peel off. ■ Compared to plating, corrosion resistance is inferior. It may discolor to red over time. ■ Typically, oil is applied after black oxidation for oxidation prevention. ■ Achieve even higher corrosion resistance with "black oxidation + top coat"!
