Title:
SURFACE-MODIFIED ALUMINUM CAN AND METHOD FOR MANUFACTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/101844
Kind Code:
A1
Abstract:
A surface-modified aluminum can, characterized in that it is a two piece aluminum can having a thickness of an aluminum material in its trunk portion of 65 to 200 μm, and almost the whole of the outer surface of the trunk portion is covered with a surface hardening layer containing 1 to 50 atom % of at least one element of nitrogen, carbon, oxygen, boron, hydrogen and phosphorus. The employment of the surface-modified aluminum can allows the reduction of the percentage of the formation of pin holes, which is a problem inherent in an aluminum can using a thin aluminum material, with little change of the present manufacturing equipment and no effect on the DI working in the manufacture thereof.
