Description of the Invention: [Technical Field] The present invention relates to an aluminum extrusion profile process, and more particularly to a process for extruding an aluminum-based composite extruded profile comprising a plurality of different series of aluminum alloys. [Prior Art] Ming alloys are widely used in raw materials such as profiles, etc. due to their lighter weight than iron-based metals and good ease of addition. Taking an aluminum extruded profile as an example, the aluminum-based alloy is pre-formed into a cylindrical aluminum ingot of a certain length, and the aluminum ingot is preheated to an unmelted plasticity, and then re-permeated; The method is such that the plastic aluminum ingot passes through the cavity of the mold to form an aluminum extruded profile product of a predetermined shape. However, the manufacture of aluminum extruded profile products is based on the use of a single aluminum alloy as a raw material. The aluminum alloy is limited by the limited alloy itself. For example, an aluminum alloy has good corrosion resistance and its strength is not high. If the aluminum alloy is made of gold, the π has a problem of supporting force and suffocation; on the contrary, when the aluminum alloy has high strength, it has no corrosion resistance, and if it is made into an inscription When i products are used, they are not suitable for use in seawater or industrial environments. Due to the durability and high strength of the material, it is not possible to combine the two different material properties, such as durability and high strength, resulting in the use of the aluminum extruded profile product. There are certain restrictions. In order to make up for the failure of the aluminum extrusion profile products, the corrosion resistance and high strength can not be combined: the shortcomings of the 'mesh' general practice is to use high-strength aluminum alloy to extrude the coffin, and then use electroplating or surface coating. Formed on the profile of Table 4 200824810 to form a corrosion-resistant coating body, the field is limited to the cover body and the aluminum squeegee ] 上 上 上 上 上 上 接合 接合 接合 接合 接合 接合 接合 接合 接合 , , , However, it is still unable to effectively overcome the problem of maintaining the state of fixation in this (4) system, so the high intensity. The invention aims to provide a profile process, and it is possible to overcome the current extrusion of aluminum alloys by overcrowding 9 materials;
