Analysis on the Market Depth of Forged Aluminum Wheels
Jun 14, 2017

With the modern car energy saving requirements continue to rise, safety and environmental regulations increasingly stringent, the requirements of more lightweight vehicle. Forged aluminum alloy wheels with its uniform density, smooth surface, thin wall, light weight, loaded with forged aluminum alloy wheels of the car safety, comfort, energy saving, and can withstand greater pressure and other advantages are constantly extended to the car wheel applications, market demand is huge.


Energy, environment and security are the three major issues of great concern to all countries in the world. The development of automobile industry and the popularization of automobile are closely related to these three problems. With the modern car energy saving requirements continue to rise, safety and environmental regulations increasingly stringent, the requirements of more lightweight vehicle. Reducing the car's own weight is one of the important measures to improve the fuel economy of the vehicle, reduce the energy consumption and improve the safety performance. 10% reduction in vehicle weight, fuel efficiency can be increased by 15%. Car weight per 100kg, 100 km fuel consumption can be reduced by about 0.7L, 1L per save of fuel can reduce CO2 emissions 2.5g. Reduce fuel consumption, reduce the discharge of CO2 to the atmosphere and harmful gases and particles has become the main direction of the automotive engineering sector.

 

With the increase in the number of cars in China, vehicle fuel consumption accounted for the proportion of total fuel consumption increased year by year. Leading to China's dependence on imported crude oil is growing, in 2009 China's dependence on foreign oil more than 50%. However, China's automobile fuel consumption level compared with foreign countries there is still a big gap. 2008 China's passenger car new car 100 km average fuel consumption of 8.03L, the European passenger car 100 km average fuel consumption down to 6.0L, Japan is 5.9L. Although China's auto industry has been fully implemented three countries emission standards, but a large number of cars in use can only meet the standards of emission standards.


The hub as an important part of the car, the car energy saving, environmental protection, safety, handling that have an important impact, so how to choose and processing shape, to achieve lightweight, far-reaching.


The basic condition of high quality automobile wheel

High-quality car wheels should have the following basic conditions:

1) light weight, low price, high surface quality, easy to shape;

2) has good static, kinetic and corrosion resistance;

3) has good rotation characteristics and thermal conductivity characteristics;

4) has a good recovery capacity, in line with environmental requirements.


Aluminum alloy light weight, high strength, good shape, affordable, high recovery rate, to reduce vehicle weight, reduce fuel consumption, reduce environmental pollution and improve operational performance is of great significance, has become the preferred material for the automotive industry. Aluminum alloy wheels are about 2kg lighter than steel hubs. When the speed is 60km / h, they can save 5% to 7% fuel, and there are quick heat dissipation, good shock absorption, long tire life, safe and reliable, beautiful appearance, colorful patterns , The size of accurate, good balance, etc., in the Western car industry has been widely used, the development potential is great.
