\ufeff<\/span>Surface Treatment \u2013 Features \/ Appearance<\/p>

Surface Treatments<\/th>Features<\/th>Appearance<\/th><\/tr><\/tbody><\/table><\/div>
Electroless Nickel Plating<\/td>A surface treatment that forms a protective film through chemical reactions without using electricity.
It enables uniform coating even on complex shapes, maintains high dimensional accuracy, and is compatible with various materials including insulators.
Widely used across industries due to its excellent performance.<\/td>		\"Electroless<\/td><\/tr>
Black Oxide<\/td>A surface treatment that forms black rust on steel surfaces to protect the underlying material.
It suppresses the formation of red rust and enhances corrosion resistance.
Its refined appearance and low processing cost make it suitable for both industrial products and interior applications.<\/td>		\"Black<\/td><\/tr>
Trivalent Chromate (clear)<\/td>A surface treatment that forms a chromium layer on metal surfaces through electrochemical reaction.
The chromium film provides high hardness, excellent wear resistance, corrosion resistance, and a mirror-like gloss.
The resulting layer significantly improves the durability and appearance of the base material.
The white tone refers to the color of the film formed after chemical treatment.<\/td>		\"Trivalent<\/td><\/tr>
Trivalent Chromate (Black)<\/td>A surface treatment that forms a chromium layer on metal surfaces through electrochemical reaction.
The chromium film offers high hardness, wear resistance, corrosion resistance, and a glossy black finish.
The coating enhances both the durability and visual quality of the material.
The black tone is the color of the film that appears after chemical treatment.<\/td>		\"Trivalent<\/td><\/tr>
Anodized (clear)<\/td>A surface treatment that forms a thick alumina layer on aluminum surfaces to improve corrosion resistance, wear resistance, electrical insulation, and dyeability.
It is especially suitable for decorative applications due to its ability to be colored.
The untreated surface appears silver-white, close to the natural aluminum base.<\/td>		\"Anodized<\/td><\/tr>
Anodized (black)<\/td>A surface treatment that forms a thick alumina layer on aluminum surfaces, followed by dyeing.
It enhances corrosion resistance, wear resistance, electrical insulation, and decorative flexibility.
The final appearance depends on the dye used, offering a satin-like finish.<\/td>		\"Anodized<\/td><\/tr>
Matt black anodize<\/td>An anodizing process combined with blasting or chemical treatment to create fine surface texture.
This treatment reduces light reflection, resulting in a matte finish ideal for optical equipment components.
The surface is dyed after treatment to achieve the desired color.<\/td>		\"Matt<\/td><\/tr>
Trivalent Chromate Passivation (SurTec 650)<\/td>It is an alternative technology to the conventional alodine treatment using hexavalent chromium and is a surface treatment developed to comply with environmental regulations (e.g., RoHS). It has excellent corrosion resistance and, unlike anodized aluminum, retains its conductivity. It is often used in the parts and housings of test equipment around electronic boards and communication equipment.<\/td>\"Trivalent<\/td><\/tr><\/tbody><\/table><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
