ALUMINUM ALLOY MATERIAL SUITABLE FOR THE MANUFACTURE OF AUTOMOTIVE BODY PANELS AND METHODS FOR PRODUCING THE SAME

摘要

An aluminum alloy material suitable for manufacturing of an automobile sheet, comprising Si of 0.6-1.2wt%,Mg of 0.7-1.3wt%,Zn of 0.25-0.8wt%,Cu of 0.02-0.20wt%,Mn of 0.01-0.25wt%,and Zr of 0.01-0.20wt%, and the rest is Al and accompanying elements. The aluminum alloy material satisfies the inequation 2.30wt%=(Si+Mg+Zn+2Cu)wt%=3.20wt%. Also provided are a method for preparing the aluminum alloy material and a final component containing the aluminum alloy material.
