(1) Compared to steel car wheels, aluminum wheels have obvious advantages: low density, about 1/3 of steel, which means that aluminum wheels of the same volume will be 2/3 lighter than steel wheels. Statistics show that the weight of the whole vehicle can be reduced by 10% and fuel efficiency can be improved by 6%~8%. Therefore, the promotion of aluminum alloy wheels is of great significance for energy conservation, emission reduction and low-carbon life.
(2) Aluminum has a high thermal conductivity, while steel has a low thermal conductivity. Therefore, under the same conditions, the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels.
(3) Fashionable and aesthetically pleasing. Aluminum alloy can be strengthened through aging treatment. Aluminum alloy wheels that do not require aging treatment have low strength and are easy to machine and shape. After corrosion resistance treatment and painting, the aluminum alloy wheels that are colored are diverse in color, delicate and beautiful.
