What materials do we usually use to process bicycle tooth plates?

The processing materials of bicycle tooth plates mainly include the following:

Aluminum alloy:

Advantages: Aluminum alloy is a commonly used material for bicycle tooth plates, which has the characteristics of light weight, can reduce the overall weight of bicycles, is convenient for riding and handling, and is an ideal choice for bicycles that pursue speed and light weight. Moreover, the machinability of aluminum alloy is good, and various complex shapes and high-precision dental discs can be manufactured through various machining methods such as CNC machining to meet different design requirements; Its cost is relatively low, and it has a high cost performance.

Disadvantages: the strength and hardness of aluminum alloy are relatively low, and problems such as deformation or wear may occur when it is used with high strength for a long time or is impacted by a large external force. However, through reasonable alloy formula and heat treatment process, the strength and wear resistance of aluminum alloy dental disc can be improved to some extent.

Alloy steel:

Advantages: Alloy steel has higher strength, hardness and good wear resistance, and can withstand greater stress and wear, so it is suitable for manufacturing high-performance bicycle dental discs. Especially on some professional or high-end bicycles, alloy steel toothed discs can provide more reliable transmission performance and longer service life.

Disadvantages: the high density of alloy steel will increase the weight of bicycles, which is in contradiction with the trend of pursuing lightweight. In addition, the processing difficulty of alloy steel is relatively high, and the requirements for processing technology and equipment are also high, which will increase the production cost.

Titanium alloy:

Advantages: Titanium alloy is a high-end material with excellent strength and hardness, which is higher than aluminum alloy and ordinary steel, but lighter than alloy steel. Titanium alloy also has good corrosion resistance and fatigue resistance, and can maintain good performance in various harsh environments. The bicycle dental disc made of titanium alloy has high reliability and durability, and is suitable for long-term high-strength use.

Disadvantages: the price of titanium alloy is very expensive, which makes the cost of titanium alloy toothed plate higher, and it is only used in some high-end bicycles or occasions with extremely high requirements on performance. In addition, the processing of titanium alloy is also difficult, which requires special processing technology and equipment.

Carbon fiber reinforced composites;

Advantages: Carbon fiber reinforced composites have extremely high strength and stiffness, and are extremely light, much lighter than aluminum alloys. This kind of material has excellent mechanical properties, which can provide excellent transmission efficiency and rigidity for bicycle tooth plates and reduce the overall weight of bicycles. Carbon fiber materials also have good fatigue resistance, corrosion resistance and long service life.

Disadvantages: The cost of carbon fiber reinforced composites is very high, and the processing technology is complex, which requires special molding technology and equipment. Moreover, the toughness of carbon fiber material is relatively poor, and it may break or be damaged when it is subjected to a large impact force.
