With the development of die casting aluminum alloys in the automotive industry, alloy wheel moulds have become the choice of many car companies. Of course, in addition to aluminum alloy wheels, there are still many cars that use steel wheels.
Then, what are the advantages of aluminum alloy wheels compared with traditional steel wheels?
Compared with steel wheel hubs, aluminum alloy material has better thermal conductivity. In addition, aluminum alloy wheels usually use narrower spokes to ensure ample space for heat dissipation.
Good thermal performance is a very important advantage of aluminum wheels. If the heat of the wheel cannot be dissipated in time, the braking effect will deteriorate, which may also lead to tire overheating and tire blowout, which has a great impact on driving safety.
In addition, good heat dissipation performance helps to protect the tires and extend alloy wheel mouldings' life.
Aluminum alloy wheels are relatively harder. There will rarely be out-of-round trouble, better smoothness when driving (especially when the car is driving at high speed), and will not feel the bumps.
Aluminum material is much less dense than steel, so aluminum wheels are usually lighter. The use of aluminum wheels makes the new safety features of the car more effective.
The precision of aluminum alloy wheel casting is much higher than that of steel wheel, and the out-of-roundness and unbalanced weight is smaller. In addition, the modulus of elasticity of aluminum alloy is smaller, and the vibration resistance is better than that of steel wheels.
Cars with alloy wheels generally use flat tires with better cushioning and shock absorption than ordinary tires, making the car much more comfortable on uneven roads or at high speeds, while effectively ensuring the safety of the car.
Alloy wheels have small deformation and low inertia resistance when rotating at high speed, which is conducive to improving the straight-line driving performance of the car. Lighter wheels can also reduce the resistance when starting and accelerating, both of which work together to make the vehicle more fuel-efficient and achieve the purpose of environmental protection.
In addition to car performance, appearance is also quite important to car sales.
Aluminum alloy has better mobility and tension than steel wheels in the high-temperature liquid state. Aluminum alloy has good plasticity, and the later polishing and plating processes enable aluminum alloy wheels to create more different appearances. In addition, the anti-corrosion surface treatment and electrostatic powder coating also make them last for a long time.
Although this article has listed many advantages of aluminum wheels, they are not perfect. The choice of wheel material. You need to consider the wheel hub from the actual situation.
Superband mold is one of the die casting mold manufacturers, has been producing aluminum alloy wheel molds for car wheel manufacturers since 1990, and is the first and largest wheel mold factory in Asia in China.
