All-aluminum body into the general trend China Zhongwang achieved important technological breakthrough

Recently, more and more car companies have joined the ranks of all-aluminum bodies, including the luxury car brand Rolls-Royce. According to foreign media reports, Rolls-Royce is planning to adopt a new all-aluminum body frame structure in its new car to reduce body weight, and is expected to be released in 2018. Demand for automotive aluminum has soared, and the market outlook has not been underestimated. Leading aluminum companies such as China Zhongwang have also accelerated related industrial processes.

China Zhongwang is the first aluminum processing company in China capable of independently designing and manufacturing all-aluminum new energy passenger car bodies. According to the Zhongrong 2015 financial report, the proportion of aluminum component products of Zhongwang New Energy Automobiles and passenger cars in the deep-processed products is gradually increasing. Zhongwang has an all-round capability from independent design to manufacturing and processing. It has made important breakthroughs in the design of complete vehicles for new energy all-aluminum pure electric vehicles and integrated design of aluminum alloy battery frame, etc., and is in line with domestic well-known passenger cars and Automobile manufacturers started technical cooperation to jointly design and develop new energy all-aluminium passenger cars and electric vehicles.

Under multiple pressures, such as environmental pollution and fuel economy, vehicle weight reduction has gradually become a consensus. According to experiments conducted by international research institutions, if the vehicle's vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6% to 8%; for every 100 kilograms of automobile conditioning quality, the fuel consumption per 100 kilometers can be reduced by 0.3 to 0.6 liters.

The use of aluminum instead of traditional steel manufacturing cars can reduce vehicle weight by 30% to 40%; use aluminum to make engines that can reduce weight by 30%; aluminum radiators are 20% to 40% lighter than identical copper products; car aluminum The body is 40% lighter than the original steel products. Therefore, the use of aluminum instead of steel made cars has significant weight loss.

According to a report by Ducker, a US market research agency, only 1% of cars are currently aluminum. It is estimated that by 2025 this figure will reach 18%. The relevant person in charge of Zhongwang said: “The company has prepared abundant resources to make necessary investment and capacity building in due course. Now that the domestic transportation industry is in a critical period of transition, many domestic automobile brands are in contact with Zhongwang, and its Designing car body materials, etc., and automakers have a delivery period of up to 7 to 8 years after deciding to use a certain manufacturer."
