7075 Aluminum CNC Turning Parts
Lightweight Precision Drive Shaft for RC Cars and Camera Drones
Product Overview
This main drive shaft is manufactured from aerospace-grade 7075 aluminum alloy through precision CNC turning processes. The surface is treated with blue anodizing to improve corrosion resistance and wear resistance. The anodized color can also be customized according to customer requirements.
These CNC turning aluminum parts are mainly used in RC cars and camera drones. By using high-strength 7075 aluminum alloy, the component significantly reduces the overall weight of the model while improving structural rigidity by approximately 25%, which can improve endurance by about 15%.
After anodizing treatment, the component offers excellent dimensional stability with low internal stress, reducing the risk of deformation during long-term use.
Material Specification
The part is made from 7075 aluminum alloy, which is widely used in aerospace and other high-performance mechanical applications.
Main alloy elements include:
• Aluminum (Al)
• Zinc (Zn)
• Magnesium (Mg)
• Copper (Cu)
These elements form the core strengthening structure of the alloy, while Chromium (Cr) acts as a key stabilizing element.
