Aluminum-magnesium alloy metal product with high welding property and oxidation resistance

Abstract

The invention relates to the technical field of product component design, and in particular to an aluminum-magnesium alloy metal product with high welding property and oxidation resistance. The aluminum-magnesium alloy metal product comprises a metal product body, a welding layer and an oxidation resisting layer; and in proportion by weight, the metal product body comprises 0.0773-0.0986% of scandium, the welding layer comprises 0.0873-0.0999% of scandium, and the oxidation resisting layer comprises 0.2-0.3 part of fullerene, 9-11 parts of polyethylene and 13-15 parts of polyacrylamide. According to the aluminum-magnesium alloy metal product, contents of scandium in the metal product body and the welding layer are adjusted, so that the welding property of the metal product can be improvedwhile the mechanical property of the metal product is ensured; and oxidation resistance is added on the surface of the metal product, so that the oxidation resistance of the welding layer and the metal product body is ensured, and the welding layer and the metal product body are prevented from being oxidized and damaged due to exposure in external environment.

Description

technical field [0001] The invention relates to the technical field of component design of technical products, in particular to an aluminum-magnesium alloy metal product with high welding performance and oxidation resistance. Background technique [0002] my country is a country rich in magnesium ore, and its mineral resources account for 50% of the world's magnesium ore. The world's magnesium ore market has been impacted by my country's magnesium ore. Magnesium alloys are cheap, which is conducive to the development of deep processing technology. Due to the lack of deep processing technology for magnesium alloys, and my country is a country rich in magnesium ore, Shanxi, Qinghai, Xinjiang, Gansu and other provinces with concentrated magnesium ore resources, many township enterprises compete to participate in mining , so that the output has increased significantly year by year, resulting in the price of magnesium alloy being 13-14 yuan / kg, while the price of aluminum is 18-20...

AI Technical Summary

Problems solved by technology

Especially in terms of welding and oxidation resistance, the welding performance and the metal performance have certain different requirements, so that the welding performance and metal performance of the aluminum-magnesium alloy cannot reach a high level at the same time.

Usually, the oxidation resistance of aluminum-magnesium alloys is improved by forming an oxide layer on the surface to ensure the oxidation resistance of aluminum-magnesium alloys, but the oxide layer will damage the welding performance and metal mechanical properties of aluminum-magnesium alloys.

[0005] It can be seen that in the metal products of aluminum-magnesium alloys in the prior art, there are defects that the weldability, metal mechanical properties and oxidation resistance cannot reach higher performance, which affects its usability
