The so-called "parallel import" comes from the concept of "medium-standard car". It means that other importers import directly from the origin except the general dealer, and their import channels are "parallel" with the domestic authorized distribution channels. According to the source of the vehicle, it can be divided into "American standard car" and "Middle East version of the car", etc., to distinguish it from the "regular car" sold by traditional channels.
At present, off-road vehicles dominate the parallel imported automobile consumer market in Yunnan, and the number of cars, trucks, MPVs and other models is small. The top models in terms of sales are Toyota (Overbearing, Cool Road), Land Rover, Mercedes-Benz, BMW, Ford (Wild Horse) and so on.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
·In 2016, the consumption of parallel imported cars in Yunnan Province exceeded 2 billion yuan
