About INOX-COLOR
INOX-COLOR GmbH, headquartered in Walldürn in the Odenwald, specializes in cross-process surface finishing of stainless steel. The service portfolio includes electrochemical processes such as electropolishing and the proprietary INOX-SPECTRAL process for coloring stainless steel without lacquer, chemical processes such as pickling and passivation, as well as mechanical processing such as grinding, brushing, mirror polishing, bead blasting and embossing (dessinage). In addition to stainless steel (V2A, V4A), aluminum, titanium, copper, brass and bronze are also processed. Components are handled from single pieces up to framework agreements of 10,000,000 pieces, from small parts as bulk goods up to XL formats of 6 x 2.5 x 2.5 m. Customers come from industries such as mechanical and plant engineering, architecture and facade construction, elevator construction, pharmaceutical and medical technology, the food industry, tank and container construction, and automotive. With around 80 employees, the company manufactures Made in Germany and supplies customers worldwide.

Materials & Processes
V2A (stainless steel)
Main material for coloring, electropolishing, pickling and mechanical processing.
V4A (chromium-nickel-molybdenum steel)
Higher-alloyed stainless steel for applications with increased corrosion requirements.
Aluminum
Finishing process-dependent for aluminum sheets.
Titanium
Finished in mechanical surface processes.
Copper
Finished in mechanical surface processes.
Brass
Finished in mechanical surface processes.
Bronze
Finished in mechanical surface processes.
INOX-SPECTRAL process
Electrochemical coloring of stainless steel without lacquer through an enhanced chromium oxide layer with interference effect.
Electropolishing
Electrochemical removal for smoothing, deburring and passivation, reduces the effective surface by up to 80 %.
inoxTEXTURE (mechanical processing)
Grinding, brushing, polishing, blasting and embossing with defined Ra values up to 6 x 2 m and 10 mm material thickness.
