Forged wheels are a type of wheel used in cars that are manufactured from a billet, or a large square piece of solid metal, which is heated to extreme temperatures and pressurized to take its shape. This thermal cycle process causes forged wheels to be stronger than cast wheels due to grain refinement. Forged wheels offer several advantages over cast wheels, including better performance and handling, better wear resistance over time, and a tighter grain structure that makes them mechanically stronger. They are also about 3 times stronger than cast wheels and 25% lighter. Forged wheels can be easily customized when it comes to finishes and offer more fitment sizes. However, the process of manufacturing forged wheels is more expensive than cast wheels, rendering them the more expensive option. Cast wheels, on the other hand, are made from aluminum that is melted into liquid form and then poured into molds. They offer a wide range of alloys to choose from and make it much easier to produce complicated parts. Cast wheels are also less expensive than forged wheels.
