At present, automobile wheels are mainly divided into steel wheels and aluminum alloy wheels. Compared with steel wheels, aluminum alloy wheels of the same volume are only one-third of the mass of steel wheels.
They have the advantages of light weight, obvious energy-saving effect, high dimensional accuracy, and fast heat dissipation, which enhances braking efficiency and improves the service life of tires and brake discs effectively guarantees the safe driving of the car. But the price is relatively high, 2-3 times that of steel wheels.
China is the world's largest aluminum wheel manufacturing base. my country's aluminum wheel production is more than half of the world's.
The product technology is mature, and its share of cost advantages is gradually increasing. From 2015 to 2020, my country's aluminum wheel production showed a trend of first increase and then decrease.
From 2018 to 2019, affected by the automotive industry downturn, wheel production continued to decline. At the same time, the Sino-US trade dispute also inhibited wheel production. Due to the automobile development cycle and the impact of the new crown epidemic, my country's aluminum wheel output in 2020 will be 161 million, a year-on-year decrease of 8.52%.
