What is the difference between forged wheels and cast wheels? How to choose?

Brakes, wheels, and shock absorbers are three-piece refitting, which are big pieces that most car enthusiasts will upgrade. Since the hub occupies a large part of the surface of the car body, it is one of the best ways to change the temperament of the vehicle and enhance the appearance of the vehicle. Therefore, the upgrade of the hub has always been a very hot topic.

However, you will definitely be faced with two choices when upgrading a wheel, whether to choose a cast or a forged one? Wheels produced by different processes have different performances in terms of safety, durability, lightweight, heat dissipation, and handling.

Cast wheels

There are generally two common manufacturing processes for cast wheels, gravity casting and low pressure casting.

● Gravity casting is to pour the liquid alloy into the mold, and then cool it to form, which is to shape the wheel hub by gravity.

● Low pressure casting is to press the liquid alloy into the mold with low pressure, and slowly solidify and form under a constant pressure. Compared with gravity casting, low-pressure casting wheels have relatively even molecules, relatively fewer pores, and a tighter metal structure. Therefore, casting wheel hub is a process form from "liquid" to "solid". The process is simple, the cost is relatively low, and the shape can be rich and diverse.

● Spinning casting-the main difference is that the spinning machine is used for rotary stamping on the basis of casting. In this process, the rim is stretched under pressure, and the aluminum alloy molecules will be tighter than simply "casting", so that the produced wheel hub is stronger and tougher, and at the same time lighter.

Forged wheels

The manufacturing process of forged wheels is to forge "solid alloys" into the shape of the wheels through high pressure (basically several thousand tons or even tens of thousands of tons of pressure). Due to multiple high-pressure collisions, the molecules between the alloys are smaller, the gaps are finer, and the density is higher. The wheel hub can achieve sufficient rigidity with less raw materials and the overall weight will be lighter. In simple terms, forging is a form of process from "solid" to "solid".

At present, forging is the method that can achieve the highest rigidity/weight ratio among all wheel manufacturing processes. Many performance control players are very keen on forging wheels. Compared with casting, forged wheels have higher strength, better safety, greater plasticity, and lighter weight. The lighter weight brings improved power and sensitivity, but the price will be higher.

How to choose forging casting

Seeing this, I believe you are already very clear about the difference between casting and forging. As for how to choose, it is still the same sentence, according to your own budget, driving habits and actual needs, rational consumption.

● If you are a friend of ordinary grocery shopping, casting will be sufficient and economical.

● If you are looking for driving experience, like going off the track, and like the passion brought by a big step on the accelerator, then forging will be more suitable, but the price is higher than that of casting.

● Spinning casting is another choice between ordinary casting and forging. If the budget is limited, but the heart desires power and speed, then spinning is also a good choice. Compared with ordinary casting, spinning wheels have better performance in terms of light weight and rigidity.

Finally, the prerequisite for buying wheels must be regular channels and regular brands. After all, this is a very important part of our driving safety! There are thousands of roads, and safety comes first.
