Description

Technical field [0001] The invention belongs to the technical field of aluminum alloy layered composite materials, and specifically relates to a high-strength, high-plastic, corrosion-resistant aluminum alloy layered composite material and a preparation method thereof. Background technique [0002] Aluminum alloy has low density, high specific strength, and excellent thermal conductivity, electrical conductivity and corrosion resistance. It is the most widely used non-ferrous metal material. With the development of modern society and economy, the service environment of aluminum alloy materials is becoming more and more complicated. Aluminum alloy materials used in corrosive media not only require high strength and high plasticity, but also have excellent corrosion resistance. However, traditional single aluminum alloy materials often cannot have both good mechanical properties and corrosion resistance. The aluminum alloy layered composite material formed by stacking aluminum all...

AI Technical Summary

Problems solved by technology

Although the interfacial bonding strength of aluminum alloy layered composites prepared by the traditional hot-rolling composite method is higher than that prepared by the traditional cold-rolling composite method, the interfacial bonding quality is still not high enough and unstable, and aluminum alloy coils cannot be used as raw materials for production. The coil weight of the obtained aluminum alloy layered composite material is small, the material utilization rate is low, the production cost is high, and it is difficult to produce an aluminum alloy layered composite material with a thinner overall thickness or a thinner cladding layer, and the uniformity and consistency of the cladding layer sex is difficult to guarantee

[0004] Therefore, in view of the problem that the traditional single aluminum alloy material cannot take into account the mechanical properties and corrosion resistance, an aluminum alloy layered composite material with high strength, high plasticity and excellent corrosion resistance is developed, and a low-cost, high-efficiency It is of great significance to efficiently prepare high-strength, high-plasticity, corrosion-resistant aluminum alloy layered composite materials
