Aluminium extruded door beam material |
摘要 |
<p>An aluminum extruded door beam includes an outer flange (F0), an inner flange (F1), and at least one web (W) for connecting the outer flange (F0) and the inner flange (F1). The outer corners at the extended ends of the outer flange have a radius R of 2.5 mm or less. The outward corners at the connections between the web and the inner flange and between the web and the outer flange have a radius R of 2 mm to 4 mm. The radius of the outward corners at the connections between the web and the inner flange and between the web and the outer flange is 1.5 to 2 times the width of the web. The length of the extended ends of the outer flange (F0) is 1 to 2 times the radius R of the outward corner at the connections between the web (W) and the outer (F0) and inner flanges (F1). The aluminum alloy extruded door beam material contains 0.8 to 1.5% by weight (hereinafter the same) of Mg and 4 to 7% of Zn, and the recrystallization surface layer has a thickness of 50 mu m or less. <IMAGE></p> |
