ALmitas+ KO (highly adhesive surface-treated aluminum alloy sheets)

Highly Adhesive Surface-Treated Aluminum Alloy Sheets, ALmitas+ KO, Manufactured Exclusively by UACJ

To meet the growing demand for composite materials and reduce environmental impact, UACJ developed ALmitas+ KO, a highly adhesive aluminum sheet featuring its proprietary surface-treatment technology.
ALmitas+ KO is manufactured exclusively by UACJ. By forming an aluminum oxide film with a unique dendritic porous structure on the surface, it provides high bonding strength.
Starting with printed circuit boards, ALmitas+ KO is expected to find use in a wide range of applications.

✓ The anchoring effect of the oxide film enables bonding with plastic materials without the use of adhesives.
✓ High adhesion makes the material ideal for combining aluminum with plastic.
✓ The oxide film is thin, allowing the material to retain aluminum’s inherent thermal conductivity, heat resistance, and workability.
✓ Environmentally friendly material containing no heavy metals

Main Applications

PCB		Commonly used and highly rated in terms of quality
Architectural interior materials		Bonding substrate for decorative aluminum sheets and laminated sheets
Transport panel materials		Panel bases for trucks and trains
Automotive parts		Bonding of plastic and aluminum
Rechargeable battery materials		Bonding bases, e.g., laminate pack and electrode tab materials
Coating substrate		Chromium-free coating substrate

Film structure

KO treatment is a surface-treatment technology in which an aluminum sheet undergoes AC electrolysis in an alkaline electrolyte to form a unique dendritic porous film on its surface. Plastic material flows into and becomes anchored in the pores, resulting in high adhesion.
