Deep Drawing and Mechanical Properties of A3003 sheet for Mobile Phone Battery Case

Abstract

Recently, a mobile machines have come into wide use rapidly, and the battery used for these purposes shoud be light and thin. Accordingly a battery case for the mobile phone should also be light and thin deep square shape. In this study, A3003 aluminum alloy was deep-drawn by 13 steps to manufacture a battery case. Mechanical properties and surface conditions of the deep-drawn sheet were investigated. Results obtained in this study show that a good battery case was successfully manufactured for mass production.
