AI Technical Summary

Problems solved by technology

However, they are basically still in the research stage. Few of them really apply large-scale lightweight materials to mass-produced models like those luxury car brands. The main reason is that the cost is the biggest concern. Steel materials are 0.8-1$ / kg. , aluminum 2.4~2.6$ / kg, resin 5~15$ / kg, carbon fiber 20~30$ / kg
Disadvantage 2 The technology is immature. At present, the key technology of lightweight materials is still in the hands of a few developed countries, such as the hydroforming of aluminum alloy and the laying technology of carbon fiber.
Domestic OEMs lack professional new material engineers, and are hazy about the performance, design, processing and recycling parameters of new materials

Abstract

The invention provides a light weight alloy material for an automobile body and belongs to the technical field of light weight of a finished automobile. The material which is smelted in a plate-like structure comprises the components in parts by weight: 10.3-21.4 parts of Mg, 17.6-33.2 parts of Ti, 45.3-57.6 parts of Al, 1.50-3.00 parts of Zn, 0.08-0.15 part of Mn, 0.05-0.15 part of Cr, 0.15-0.35 part of Cu, 0.28-0.45 part of Si and less than or equal to 0.10 part of Fe. The light weight alloy material for the automobile body provided by the invention is used in automobile manufacturing. The produced automobile has the characteristics of light weight, less oil consumption, less emission of waste gas and the like; not only are resources and cost saved, but also the environment is protected.

Description

technical field [0001] The invention relates to a lightweight alloy material for automobiles, and also relates to a hot forming process for lightweight alloy materials for automobiles, and belongs to the technical field of lightweight automobiles. Background technique [0002] The lightweight of the car refers to reducing the curb weight of the car as much as possible on the premise of ensuring the strength and safety performance of the car, so as to improve the power of the car, reduce fuel consumption, and reduce exhaust pollution. Experiments have shown that if the weight of a car is reduced by half, the fuel consumption will also be reduced by nearly half. For every 10% reduction in vehicle weight, fuel efficiency can be increased by 5% to 7%; for every 100 kg reduction in vehicle curb weight, fuel consumption per 100 kilometers can be reduced by 0.3 to 0.6 liters; exhaust emissions can be reduced by 8 to 11 grams. Due to the needs of environmental protection and energy...
