Aluminum two-wheel vehicle parts

Product: Hot forged aluminium parts for two-wheel riding vehicles

1. High quality aluminium alloys are chosen based on the required mechanical properties. Common alloys for motorcycle components include 6061 and 7075. These alloys offer a good balance of strength, ductility, and corrosion resistance.

2. Forging: 

- Heating: The aluminium billet is heated to a specific temperature range (usually between 400 - 500°C for 6061 alloy) to increase its plasticity and make it suitable for forging.

- Die Design: Custom-designed forging dies are used to shape the billet into the desired component. The dies are precision - machined to ensure accurate dimensions and surface finish.

- Forging Operation: The heated billet is placed in the die, and pressure is applied using a forging press. This can be done through open - die or closed - die forging, depending on the complexity and precision requirements of the part. Closed - die forging is often preferred for motorcycle components due to its ability to produce complex shapes with tight tolerances.

3. Heat Treatment:

- After forging, the parts undergo heat treatment processes to enhance their mechanical properties. This may include solution heat treatment, quenching, and aging. For example, 6061 alloy parts are solution heat - treated at around 530°C, quenched, and then aged at 175°C to achieve optimal strength and hardness. 

4. Machining and Finishing:

- Precision machining is performed to achieve the final dimensions and surface finish. This may involve milling, drilling, and turning operations. Surface treatments like anodizing or powder coating can be applied to improve corrosion resistance and appearance.

Functions

1. Structural Support

These aluminium forged parts are often used in the motorcycle's suspension or frame systems to provide structural support. They help in maintaining the integrity of the motorcycle's structure during riding, especially when subjected to dynamic loads.

2. Weight Reduction

Aluminium is significantly lighter than steel. Using aluminium forged parts helps in reducing the overall weight of the motorcycle, which can improve fuel efficiency and handling performance.

3. Corrosion Resistance:Aluminium alloys have inherent corrosion - resistant properties, making these parts suitable for use in various environmental conditions.

Characteristics

1. High Strength-to-Weight Ratio: Aluminium forged parts offer excellent strength while being lightweight. This characteristic is crucial for motorcycle components, as it enhances performance without sacrificing durability. 

2. Ductility:   - Aluminium alloys are ductile, allowing the parts to deform slightly under load without cracking. This property is beneficial for components that may experience shock loads or vibrations during motorcycle operation. 

3. Precision and Complexity: The forging process, especially closed - die forging, allows for the production of complex shapes with high precision. This enables the manufacturing of components with intricate geometries that are required for specific motorcycle functions. 

4. Surface Finish: Forged aluminium parts can have a smooth surface finish, which can be further enhanced through machining and surface treatments. This not only improves the aesthetic appeal but also reduces friction in moving components.
