"PEO" is an anodizing method that generates an insulating film under spark discharge (plasma emission), producing a ceramic coating that has better adhesion and superior film strength compared to anodized coatings. It is possible to process in white (PEO "white") or black (PEO "black"), and uniform film formation can also be achieved on corners. Additionally, treatments for magnesium (Mg-PEO) and titanium (Ti-PEO) are also possible. 【Features】 ■ White and black processing available ■ Uniform film formation possible on corners ■ Ceramic coating with excellent film strength can be obtained *For more details, please refer to the PDF document or feel free to contact us.

The "chemical film" is a protective coating that forms on the surface of aluminum. It achieves a beautiful color tone ranging from pale yellow to yellow-brown and passes the 168-hour salt spray test, showing no signs of corrosion or pitting. The electrical resistance of the coating is extremely low, making it suitable for products that require electrical conductivity, such as electrical and electronic components. 【Features】 ■ Achieves a beautiful color tone ranging from pale yellow to yellow-brown ■ High adhesion for painting, used as a surface treatment for painting ■ Passes the 168-hour salt spray test with no corrosion or pitting ■ Extremely low electrical resistance of the coating ■ Ideal for products that require electrical conductivity, such as electrical and electronic components *For more details, please refer to the PDF document or feel free to contact us.

"Hard anodizing" is a hard coating obtained by anodizing at a high current density in a sulfuric acid solution. It has high corrosion resistance, passing a salt spray test for 336 hours at a standard thickness of 50μm, and since the coating thickness can be adjusted, it can accommodate various applications and product dimensional tolerances. A coating of similar quality can also be produced on materials generally considered difficult to hard anodize, such as 2000 series aluminum alloys and castings. 【Features】 - High corrosion resistance, passing a salt spray test for 336 hours at a standard thickness of 50μm - Adjustable coating thickness (standard 50μm, 20–70μm) - Can accommodate various applications and product dimensional tolerances - High wear resistance even in harsh operating environments (Diano) - No coating delamination observed even in a 90-degree bend test *For more details, please refer to the PDF document or feel free to contact us.

"Sulfuric anodizing" is a coating obtained by anodizing in a sulfuric acid solution. It has high corrosion resistance, passing a standard 10μm salt spray test for 336 hours, and the resulting coating has good transparency, allowing the aluminum metal surface to be utilized as is. In process management tests, a coating mass that meets the MIL-A-8625 standard value of over 1000mg/ft² has been achieved, maintaining good coating density across various materials. [Features] ■ High corrosion resistance ■ Coating thickness can be adjusted from 2 to 25μm ■ Can utilize the aluminum metal surface as is ■ Appearance can be altered through dyeing ■ Available in black, blue, red, orange, and other colors *For more details, please refer to the PDF document or feel free to contact us.
