A cast wheel is a wheel made from cast metal, typically an aluminum alloy. Unlike steel wheels, which are made from stamped sheets of metal, a cast wheel is more complex to manufacture and offers several advantages over steel wheels.

Cast wheels are usually lighter than steel wheels, which helps reduce the weight of the vehicle and improve fuel efficiency. They can also be available in a wider range of designs and sizes to enhance the appearance and performance of the vehicle.

In addition, cast wheels can provide better driving and handling characteristics due to their higher strength and stiffness. They are also generally more resistant to corrosion and damage from road conditions such as potholes.

A flow formed wheel is manufactured using a special production process in which an aluminum preform is spun under high pressure and high heat while being drawn through a specialized mold. This process creates a wheel with a very strong outer layer and a thinner inner layer, resulting in high strength and stiffness.

The process of manufacturing flow formed wheels is also known as "spin forming" and is a combination of casting and forging. By spinning the blank and drawing the material, the aluminum is compacted and reinforced, resulting in a wheel with high strength and low weight.

Compared to traditional cast or forged wheels, flow formed wheels have several advantages. They are usually lighter than cast wheels and more cost-effective than forged wheels, but offer similar benefits in terms of strength and performance.

Due to their high strength, stiffness, and durability, flow formed wheels are often used in the motorsport industry, but they are also a popular choice for street vehicles seeking improved performance and aesthetics.

A forged wheel is a wheel made from forged aluminum. Compared to conventional cast wheels, forged wheels are usually lighter and stronger. They are often used in racing cars and sports cars to reduce the overall weight of the vehicle and improve performance.

By using forged wheels, the braking performance of the vehicle can also be improved as they offer higher heat dissipation and greater stiffness. However, forged wheels are typically more expensive than conventional cast wheels.
