A brushed finish creates a unidirectional satin texture, reducing the visibility of marks and scratches on the surface.
Anodizing increases corrosion resistance and wear properties, while allowing for color dyeing, ideal for aluminum parts.
Black oxide is a conversion coating that is used on steels to improve corrosion resistance and minimize light reflection.
Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.
