What is the difference between forged wheels and cast wheels

Process differences

Forged wheel hubs are formed by stamping heated aluminum ingots using a 10000 ton pressure machine, resulting in a tight molecular structure and high metal density; Casting wheels involves pouring liquid aluminum water into a mold to cool and form, followed by polishing, deburring, and other processing.

The forging process makes the wheel hub lighter, about 20% lighter than casting in the same size, with better strength and impact resistance, suitable for intense driving or racing scenes; The casting process has low cost and short production cycle, making it more suitable for daily household use.

performance comparison

The 18 inch forged wheel hub weighs about 7.5kg, while the cast one weighs about 9kg. The total weight of the four wheels is 6kg lighter, which is equivalent to carrying one less child; The impact resistance of forging is more than 30% higher than that of casting, and it is not easily shattered after impact, while casting is prone to deformation; Forging has higher heat dissipation efficiency and is more stable during continuous high-intensity driving, while casting performance may be affected in continuous high temperature environments.

Price and Applicable Scenarios

Forged wheel hubs start at a cost of 5000 yuan per unit and are the preferred choice for high-end car models or performance modifications; Casting a single wheel hub costs 800-2000 yuan, which is economical for daily commuting. It is recommended to choose low-pressure or spinning casting technology. Ordinary household cars do not need to blindly pursue forging, casting wheels can already meet the demand; If it involves track driving or high-end modification, the lightweight and high-strength advantages of forging are more significant.

the way to distinguish

Look at the label, the inner wall of the forged wheel hub is usually engraved with the words "FORGED"; Touch the surface, both the front and back of the forging are smooth without sand holes, and there may be demolding marks on the back of the casting; Listen to the sound, the forging sound is crisp when struck, while the casting sound is dull; Weighing, forging of the same size is noticeably lighter. Through these methods, it is possible to quickly distinguish between two types of wheel hubs.

When choosing wheels, it is necessary to consider one's own needs and budget. Pursuing ultimate performance, lightweight handling, and sufficient budget, forging can be chosen; Focusing on cost-effectiveness and meeting daily commuting needs, casting is a more suitable choice. Reasonable selection based on actual usage scenarios is necessary to maximize the effectiveness of the wheel hub.
