Aluminum alloy wheels are mostly made of aluminum as the basic material, and are suitably added with metal elements such as manganese, magnesium, chromium, and titanium. Its advantages are light weight, high manufacturing accuracy, high strength, low inertia resistance, strong heat dissipation ability, good visual effects, etc.,

Steel wheel hub

The main advantages of a steel wheel hub hub are the simple manufacturing process (generally the casting process), the relatively low cost, and the strong resistance to metal fatigue. However, the shortcomings of steel wheel hubs are relatively prominent: ugly appearance, large weight, large inertia resistance, poor heat dissipation, and very easy to rust.

Involved materials: carbon steel, ductile iron

Magnesium alloy wheel hubs

Magnesium alloy is a metal material that has received wide attention in the field of automotive and electronic products in recent years, and is the lightest structural material currently used. Due to its light weight (specific gravity of 1.74 g / cm3) and good mechanical properties, it has begun to be used in batches in the vehicle and electronics fields.

Carbon fiber composite wheel hub

Composite materials are materials with strong vitality that emerged from the development of modern science and technology. Because the composite material has special vibration damping characteristics, it can reduce vibration and noise, and has good anti-fatigue performance. It is easy to repair after damage, and it is convenient for integral molding. Therefore, it can be used to manufacture automobile body, force member, transmission shaft, engine frame and its interior. member. Of course, the price has always been high. In terms of automobile lightweight manufacturing, its popularity is far lower than that of aluminum alloys.
