Lossless wheel hub forming
There are differences in materials and processes. The casting raw material is A356.2, which is cooled by molten aluminum and has high density. Forging is 606 1 series aluminum, which is formed under the pressure of up to 10000 tons, so the price is relatively expensive. I bought a magnesium card forged wheel hub before, which is expensive, but light, comfortable to drive, more stable than before, and feels very different.
