[Technical Documentation] Heat Treatment and Softening Quality of Aluminum Foil, Case Studies of Defects and Their Causes
For those using aluminum foil! This is a technical document that explains the heat treatment and softening processes that determine the surface properties of aluminum foil, along with examples of defects and their causes.
Typically, the surface of aluminum foil retains rolling oil (mineral oil) used as a lubricant during the rolling process. This is removed during the heat treatment and annealing process when the aluminum foil is softened. On the other hand, if the conditions are not set properly, various issues may arise. This document will introduce the phenomena and causes of the issues that occur in this process.
