SMM5, March 17-as an emerging auto power, China has become the world's largest auto producer and the largest new car consumer market with the largest capacity. Reviewing the data of automobile sales in China in 2018, the production and sales of passenger cars in 2018 were 23.529 million and 23.71 million respectively, down 5.2% and 4.1% respectively compared with the same period last year, and the growth rate was lower than that of the industry as a whole. This is also the first decline in China's automobile industry since 1990.

However, the 13th five-year Plan period is the key period for China to implement the "made in China 2025", adjust the industrial structure and promote the transformation and upgrading of the manufacturing industry. As an important benchmark of China's manufacturing industry and national defense capability, it is imperative to increase the application of material innovation, energy innovation and technological innovation in the automobile field, vigorously promote automobile green intelligent manufacturing, and reduce vehicle emissions and energy consumption.

It is predicted that in 2020, the amount of aluminum used in domestic vehicles will reach 190kg/, new energy vehicles can reach 200kg/, aluminum alloy is more and more used as automobile structure, but there are still a lot of problems. At the same time, we also have to face many challenges in the development of materials and processes.

The main results are as follows: 1. The challenges of deformed aluminum alloy for automobile structure parts are: stability of performance; higher static performance; higher fatigue performance.

2. Challenges in the development of cast aluminum alloy materials for automotive structural parts: limited connection mode: welding, riveting; poor static performance; poor fatigue performance.

As an aluminum alloy material R & D and manufacturing enterprise in the upper reaches of automobile industry chain, we should join hands with automobile enterprises, parts enterprises and relevant scientific research institutions at the critical time point of industry transformation and upgrading, including, but not limited to, the following important issues:

The main results are as follows: 1. Without increasing the cost, develop a new type of aluminum alloy for high strength and toughness structure, such as microalloying, thermal deformation, heat treatment and so on.

2. To explore new technology and new method to improve the factors of increasing strength and toughness, such as uniform composition, dense microstructure, grain refinement and so on.

3. To expand the application of high strength and toughness aluminum alloy in automobile and other fields;

The Shanghai Nonferrous Metals Industry Association and Shanghai Nonferrous Network focus on the development direction of the industry, and at the same time, work together with the major associations and institutions of the industrial chain to produce the first edition of the Guide for the purchase of Aluminum Alloy Materials for Automobile use in China for the automobile industry chain. The purpose of this paper is to provide an authoritative, comprehensive and professional supplier list of aluminum alloy materials for automobile enterprises, to establish a bridge between aluminum alloy material enterprises and automobile enterprises, and to promote the application of aluminum alloy materials in automobile.

The latest co-production units are announced:

Special co-production units: China Renewable Resources Industry technological Innovation Strategic Alliance, Suzhou Die casting Technology Association, Shanghai Nonferrous Metals Industry Association

Name: Huagin Aluminum Co., Ltd.-Nantong Hongjin Metal Aluminum Co., Ltd.

Joint production units: Guangdong Gold Aluminum Light Alloy Co., Ltd., Shanghai Zhejiang East Aluminum Co., Ltd., Shandong Yuhang Special Alloy equipment Co., Ltd., Chongqing Jiantao Aluminum Co., Ltd., Shenyang Donghuan Nonferrous Metals Manufacturing Co., Ltd., Quzhou Dongfa Aluminum Co., Ltd., Guangdong Zengfeng Intelligent equipment Co., Ltd., Guangdong exquisite Special profile Co., Ltd.

Therefore, the industrial chain has passed the IATF16949 system certification of deformed aluminum alloy, cast aluminum alloy material enterprises, according to the requirements to provide audit materials, apply for entry into the supplier list. At the same time, enterprises that meet the requirements (aluminum alloy materials enterprises, die casting enterprises, parts enterprises) are cordially invited to participate in the joint production of the list to contribute to the transformation and upgrading of the automobile industry chain.
