Enterprises through the use of aluminum alloy wheels to optimize the overall weight of the body, improve operational efficiency. It is one of the main practices of the domestic OEMs and vehicle users. Aluminum alloy wheels are lighter weight than other wheel, this means that vehicles can carry more than half a ton of goods for users to create more revenue. Secondly, in the actual use of the traditional steel wheels used for too long, or often bumpy sections will be deformed. The aluminum alloy wheel processing high precision, anti-deformation ability is far superior to the steel ring, the product roundness is good, to further enhance the smooth driving of the vehicle. Aluminum wheels are lighter in weight than traditional steel wheels and have less rolling inertia, which means saving more fuel for users.
