Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings, but the implementation scope of the present invention is not limited.
[0024] Please refer to figure 1 As shown, the method includes the following steps:
[0025] Provide at least two aluminum-series alloys of different materials, which can be selected from any series of aluminum-series alloys of the 5 series and 7 series in the AA specification formulated by the world-wide American Aluminum Alloy Association, or selected from the 5 series Series and 7 series are two different series of aluminum alloys, among which 5 series is better to choose aluminum alloys such as 5051, 5052, 5056, 5083, 5086, 5456, etc. The main components of the aforementioned 5 series aluminum alloys include aluminum ( Metal elements such as Al) and magnesium (Mg), which have excellent corrosion resistance and good weldability and other material properties, have strong corrosion resistance to s...

The invention provides a method for preparing an extruded shape of composite material with aluminum and the extruded shape. The method comprises the steps that: at least two different aluminum alloys with different materials, among which, one aluminum alloy is selected as core material and the aluminum alloy with the material different from that of the core material is at least processed to form a hollow outer covering body which is combined with the outside of the core material so as to prepare a aluminum-alloy ingot; the ingot is then heated to the degree of plasticity and next shaped into a double-layer long-profile extruded shape product with an outer layer and an inner layer containing the aluminum alloys with different materials by extrusion, therefore, the two kings of aluminum alloys with different materials are combined as a whole so as to ensure that the extruded shape product combines the characteristics of the aluminum alloys with different materials and the aluminum alloys at the outer layer and the inner layer of the product are in a concretion state.
Description
technical field [0001] The invention provides a method for preparing aluminum extruded profiles, in particular to a process design for extruding aluminum-based composite materials containing several different series of aluminum alloys. Background technique [0002] Aluminum-based alloys have been widely used as raw materials for products such as profiles due to their lighter weight and better processability than iron-based metals. Taking aluminum extruded profiles as an example, the aluminum alloy is prefabricated into a cylindrical aluminum ingot of a certain length, and then the aluminum ingot is preheated to the plasticity without melting, and then extruded through an extrusion molding machine to make The plastic aluminum ingot passes through the cavity of the mold to make an aluminum extruded profile product of predetermined shape. [0003] The manufacture of existing aluminum extruded profile products uses a single type of aluminum-series alloy as a raw material. The a...
