The materials of automotive wheel hub units are diverse, mainly including steel, aluminum alloy, magnesium alloy, and carbon fiber composite materials. The following is a detailed introduction to these materials:
Steel wheel hub:
Material: Made of steel. Advantages: low cost, low cost, simple manufacturing process, strong resistance to metal fatigue. Disadvantages: Poor heat dissipation, easy to rust on rainy days, heavy weight, and high inertia resistance.
Application: Commonly used in economical vehicle models or cost sensitive vehicle models such as trucks and vans.
.Aluminum alloy wheels:
Material: The main material is aluminum, with added metal materials such as manganese and magnesium.
.Advantages: Lightweight, 30%~40% lighter than steel wheels, can reduce car energy consumption and improve acceleration performance;
; Good heat dissipation performance helps reduce the incidence of tire blowouts; High manufacturing precision, high strength, low inertial resistance, and excellent visual effect. Disadvantage: Relatively high cost.Application: Widely used in household cars SUV、 Luxury brand car models, etc.
Magnesium alloy wheels:
Material: The main material is magnesium, and other metal materials are added.
. Advantages: The lightest weight, good shock absorption performance, easy heat dissipation, and strong corrosion resistance. Disadvantages: High cost and relatively complex manufacturing process.Application: Popular among car owners who pursue lightweight and high-performance, but with a relatively small market share.
.Carbon fiber composite wheel hub:
Material: Made of composite material.
. Advantages: Good noise resistance, easy to repair after damage, lightweight. Disadvantages: High cost and high manufacturing process requirements.Application: Mainly used for high-end models or special vehicles that pursue ultimate performance.
