Market analysis of global precision aluminum alloy structure manufacturing industry

Datetime: 2018-01-30 20:12:55    Views: 820
At present, the production and consumption of aluminum alloy structure in the world is mainly concentrated in the United States, Japan, China, Germany, Italy and other countries and regions. In recent years, the use of aluminum alloy in automobile has been increasing rapidly, and the permeability of the market is increasing.

1. Application range and precision requirement of aluminum alloy in automobile field

Experiments show that if the vehicle weight is reduced by 10%, fuel efficiency can be increased by 6%-8%; vehicle kerb mass decreased by 100 per kg, 100 km fuel consumption can be reduced by 0.3-0.6; the weight of the car is reduced by 1%, fuel consumption can be reduced by 0.7%. At present, due to the need of environmental protection and energy saving, the lightweight of automobile has become the trend of automobile development in the world.

The precision aluminum alloy structural parts are mainly used in the field of automobile parts, such as cooling system, vibration damping system, micro motor, power system and so on. Aluminum Alloy materials in automotive lightweight to promote an important role in the process based on the scope of its application in automobile is more and more wide application range from Zui at the beginning of the engine block, gearbox, wheels and other extended to all important parts of body, and there have been all aluminum cylinder engine. The effect of weight loss is very obvious (can lose weight more than 30kg). The Aluminum Association, if the weight loss of 25%, can make the car up to 60mph from the original 10 seconds down to 6 seconds; due to the use of Aluminum Alloy profile is not under the condition of reducing vehicle volume reducing vehicle weight, thus making the car more stable, the impact section structure can absorb Aluminum Alloy more energy, so it is more safe and comfortable.

At present, more than 90% of the extruded aluminum materials used in automobiles are produced by 6XXX alloy, and only a few are extruded with 3XXX, 5XXX and 7XXX alloys. Most of the extruded sections and pipes are used in the manufacture of automobile parts. At present, the all aluminum body structure of passenger cars is made up of some foreign high-end sports cars, such as Audi A8 and A2, Jaguar XJ, etc., for combination of profiles, plates and castings.

The precision aluminum alloy products used in automobile field mainly include cooling system structure, micro motor structure and damping system structure. The precision requirements of each component are as follows:

2. Aluminum alloys in the European and American automobile market have been widely used

For the European auto market, by 2020 the use of aluminum alloy will be 180kg. According to the statistics of the European Aluminum Association and Ducker Worldwide, from 1990 to 2012, the use of aluminum alloy from cars increased from 50kg to 140kg, and the amount of aluminum alloy used for bicycles will reach 180kg in 2020. Among them, A8, Jaguar and Land Rover XJ and Land Rover in high-end cars have reached 500kg. In 2012, 140kg Aluminum Alloy bicycles in the hub accounted for approximately 20%, accounting for nearly 30% of engine parts, transmission accounted for 10%, accounting for 8% of the heat exchanger, the doors, hood and other structural parts accounted for 5%, accounting for 5%, steering and braking system accounted for 7%, accounting for 3% of the bumper.

According to the investigation of Drive Aluminum, in the North American automotive market, Aluminum Alloy began to be used in heat exchanger in 1980, 1990 began to use in the hub and the engine assembly, after the start can be applied in the bumper and hood, now began to promote the use of main body. Drive Aluminum statistics in 2012 the North American single vehicle aluminum amount to 158kg, is expected to be up to the average amount of aluminum up to 250kg in 2025. In 2015, the aluminum alloy used in automobiles in North America accounted for 73% of the total casting aluminum alloy. It was mainly used for engine assembly, gearbox and heat exchanger parts, and the deformation aluminum alloy accounted for 27%. It was mainly used for parts such as body, structural parts and engine cover.

3. The permeability of aluminum alloy in auto parts is increasing

The body is a big Zui growth point in the future of aluminum alloy in the car, and the engine assembly is also a large amount of excavation space.  According to Drive Aluminum statistics, the market penetration of aluminum alloy in car body and cover was only 6.6% in 2015. With the increasing noise of low emission reduction, the market penetration of aluminum alloy will reach 26.6% by 2025. The permeability of the cover will reach 85%, the whole aluminum body permeability will reach 18%, and the permeability of the door will reach 46%. For the engine cylinder, the market penetration of aluminum alloy in North America is expected to reach 85% by 2025. It is expected that by 2025, the total demand for aluminum alloy in the North American automobile market is 4 million 540 thousand tons, and the market space is huge.
