Problems solved by technology

However, due to the brittle phase β-AlFeSi, coarse Mg 2 The presence of Si, excess Mg or Si, etc., causes the surface defects of various extrusion materials that are sensitive to speed to easily occur, such as pits, pockmarks, die marks, etc. Therefore, a lower extrusion speed has to be exchanged for Satisfactory extrusion surface
This makes the production efficiency very low and the production cost of the product is very high

Abstract

The invention discloses an aluminum alloy material capable of being molded by high-speed extrusion, which comprises the following components in percentage by weight: 0.11-0.15% of Mn, 0.11-0.15% of Cu, 0.38-0.46% of Si, 0.47-0.55% of Mg, 0-0.25% of Fe, 0-0.02% of Cr, 0-0.02% of Zn, 0-0.02% of Ti, and the balance of Al. The invention also discloses a preparation method of the aluminum alloy material capable of being molded by high-speed extrusion; and compared with traditional aluminum alloy 6063, the speed for extruding sectional materials by the aluminum alloy material can be improved greatly, and the production efficiency of the aluminum alloy sectional material can be enhanced remarkably.

Description

technical field [0001] The invention relates to an aluminum alloy, in particular to an aluminum alloy material suitable for high-speed extrusion and a preparation method. Background technique [0002] Among the aluminum alloys used for extrusion production, the most widely used is the 6063 alloy. However, due to the brittle phase β-AlFeSi, coarse Mg 2 The existence of Si, excess Mg or Si, etc. leads to the easy generation of surface defects of various types of extrusion materials that are sensitive to speed, such as pits, pockmarks, die marks, etc. Therefore, a lower extrusion speed has to be used in exchange for Satisfactory extrusion surface. This makes the production efficiency very low, and the production cost of the product is very high. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to aim at the above-mentioned defects existing in the existing 6063 aluminum alloy. On the basis of the existing 6063 aluminum alloy, by changing the element...
