What is the difference between MN MODEL MN82S metal steering shaft and plastic?

Metal steering shaft: Usually made of high-strength metal (such as aluminum alloy, steel, etc.). It has excellent strength and durability and can withstand large loads and impact forces. It has high hardness and is not easy to deform or wear.

Plastic steering shaft: Made of plastic materials (such as nylon, ABS, etc.). The strength and durability are relatively low, but the weight is light, which helps to reduce the overall weight of the vehicle. The hardness is low and may be more susceptible to wear and deformation.
