High Purity Aluminum Foil

The 8µm Ultra Clean Aluminum Foil is used for batteries undergoes an acidic cleaning process to remove oil residues and impurities during production, with no barrier coating applied. Compared to conventional aluminum foil, it imposes extremely stringent requirements on parameters such as thickness, strength, and surface cleanliness, aiming for the thinnest possible thickness, highest strength, optimal dyna value, and the most pristine surface quality.

The 9μm Ultra Clean Aluminum Foil is designed for lithium battery applications, ultra-clean aluminum foil undergoes acid washing during manufacturing to eliminate surface oil stains and micro-impurities, without any barrier coating on its surface. Unlike standard aluminum foil, it adopts far stricter production standards for thickness, tensile strength and surface cleanliness. Its production targets ultra-thin gauge, superior mechanical strength, ideal Dyna value and spotless surface condition.    

The 12µm High Purity Aluminum Foil is used for batteries ,which undergoes an acidic cleaning process to remove oil residues and impurities during production, with no barrier coating applied. Compared to conventional aluminum foil, it imposes extremely stringent requirements on parameters such as thickness, strength, and surface cleanliness, aiming for the thinnest possible thickness, highest strength, optimal dyna value, and the most pristine surface quality.

The 13μm Ultra Clean Aluminum Foil is tailored for battery use, which is acid-cleaned to remove oil and impurities during production and remains uncoated. It carries stricter specifications for thickness, strength and surface purity than regular aluminum foil. Manufacturers produce it to realize thin gauges, high strength, perfect Dyna performance and flawless surfaces.
