Many models have already used aluminum alloy casting wheels. The aluminum alloy wheels are divided into casting and forging. The original factory is generally cast. While forged wheels are more expensive, first understand the advantages and disadvantages of both:
The main advantage of the original casting wheel is that the manufacturing process is simple, the cost is relatively low, and there is no limitation on the shape; the disadvantage is that the strength is low, the weight is large, the heat dissipation is poor, and it is easy to be pulverized after a severe impact.
The forged wheel hub is the most advanced method for manufacturing aluminum rims. Its most outstanding advantages are high strength, higher safety, strong plasticity, light weight, good heat dissipation and fuel saving. The disadvantage is that the price is slightly higher and the production cycle is long.
What are the benefits of forged wheels compared to original cast wheels?
1.Rugged and safer
The forged aluminum ring is 1-2 times stronger than the cast aluminum ring, which is 4-5 times that of the general iron ring. Therefore, it is more durable and impact resistant. The toughness and fatigue resistance are also significantly better than the casting wheel. It is not easy to be crushed and broken, and the safety is more. Strong.
2.Lighter and more fuel efficient
Compared with casting, the same size forged wheel can be about 20% lighter in weight, and 10K horsepower can be increased by 1KG on the wheel. In addition, the weight reduction also makes the suspension reaction speed significantly improved, the suspension system reacts faster, and the processing of the road surface is more convenient, and the bumpiness is greatly reduced.
3.Good fuel economy and heat dissipation
According to the Japanese experiment, the weight of a 5-seat car is reduced by 1kg, and about 20L of gasoline is saved in one year. According to a research report published by the American Society of Automotive Engineers, although the forged wheel is more expensive than the general casting wheel, in the long run, the car arrives. The cost can be recovered from 1-3 million kilometers. In addition, the forged wheel has better heat dissipation effect, and the long-distance high-speed driving can make the brake drum and the tire not easy to age, increase the life and reduce the chance of puncture.
4.Better handling
The upgraded forged hub increases the width of the hub without affecting the steering and loading, so that the acceleration of the vehicle, the sensitivity of the brakes and the curve will be significantly improved, whether it is from rest to start or acceleration during driving. Feel more brisk, no matter whether you bend or bend in the corner, the car will obviously feel the lightness under your feet.
5.More beautiful
Because the forged wheel hub is compact and can withstand high stress, it can design some relatively thin and thin spokes in the design, and the design has high degree of freedom. It can design the wheel hub suitable for the overall appearance of the customer’s car according to the owner’s needs. Cars are more personal.
In fact, in order to reduce costs, 99% of the wheels on the market are cast wheels. Only high-end performance models will use high-end forged wheels, which is not only for more beautiful and lightweight, but also for safety.
