It is a technology characterized by corrosion resistance, heat resistance, and rust prevention in black plating treatment.
"Black chrome plating" is a surface treatment that coats the surface of a metal with a thin film of black chrome (approximately 0.1 to 1.0 μm). It is considered a treatment that requires advanced technology due to the tendency for processing unevenness and scratches to be noticeable. It has corrosion resistance, heat resistance, and appearance comparable to standard silver chrome plating, and it is widely used for decorative parts because it achieves a deep black finish. [Features] - A treatment that requires advanced technology due to the visibility of processing unevenness and scratches - Excellent heat resistance and appearance - A coating with particularly high corrosion resistance compared to other blackening treatments - Good adhesion as a base for painting - After plating, it is also possible to enhance the surface gloss with a lubricant *For more details, please refer to the PDF document or feel free to contact us.
