Through advanced CNC milling processes such as:
Profile machining & Pocket milling
Precision drilling & Thread tapping
Multi-axis machining (including 3-axis, 4-axis, and 5-axis milling)
7075 aluminum can be manufactured into complex components with accurate dimensions and functional surfaces.
Typical customized parts include:
Structural brackets & Precision mounting plates
Robotic components & Industrial fixtures
Mechanical connectors & Lightweight equipment parts
Key Advantages of CNC Milled 7075 Aluminum Parts
High Strength-to-Weight Performance
The most significant advantage of 7075 aluminum is its ability to provide high mechanical strength while maintaining low weight.
• Tensile strength: Approximately 570 MPa
• Yield strength: Approximately 500 MPa
• Density: Approximately 2.81 g/cm³
These characteristics make 7075 aluminum suitable for industries where reducing component weight while maintaining structural performance is important. Compared with heavier metal materials, 7075 aluminum components can help improve equipment efficiency, reduce overall weight, and provide excellent mechanical reliability.
Precision CNC Machining Capability
7075 aluminum requires proper machining control due to its higher hardness and strength compared with common aluminum alloys. Our production facility utilizes high-precision CNC machining centers, focusing on:
Optimized cutting parameters for high-hard alloys
Premium tooling selection and rigid workholding
Stable machining conditions & Controlled production procedures
This enables the production of complex geometries, tight tolerance features, and precision assembly components. For OEM customers, accurate machining helps reduce assembly problems and improves product consistency during mass production.
Tight Dimensional Control
Precision is critical for aluminum components used in mechanical assemblies and industrial equipment. Our machining capability includes:
• Standard tolerance: ±0.05 mm
• Critical dimensions: Up to ±0.01 mm (depending on part design, material condition, and inspection requirements)
