Title:
ENVIRONMENT-FRIENDLY LIGHTWEIGHT ALLOY MATERIAL FOR PRODUCTION OF ELECTRIC VEHICLE UNDERTRAY
Document Type and Number:
WIPO Patent Application WO/2023/028994
Kind Code:
A1
Abstract:
An environment-friendly lightweight alloy material for the production of an electric vehicle undertray, relating to the technical field of electric vehicle undertray production. The specific production steps comprise: S1, preparation of a quartz fiber screen mesh; S2, smelting; S3, refining and impurity removing; S4, casting; and S5, hot extrusion forming. For the environment-friendly lightweight alloy material for the production of the electric vehicle undertray, magnesium can improve the corrosion resistance of the alloy material, copper can improve the machinability, tensile strength and impact toughness of the alloy material, and the increased flexibility of the alloy material by using titanium can further improve the toughness of the alloy material and reduce the possibility of cracking; moreover, the mechanical properties of the undertray made of the alloy material can be improved by the provision of the quartz fiber screen mesh, and even when the undertray made of the alloy material is cracked due to impact, the quartz fiber screen mesh can reduce the possibility of falling off of cracked parts, so that the cracked parts still have a connection effect.
