Aluminum Impeller
This precision aluminum impeller is a high-performance rotating component built for turbochargers, air compressors, industrial blowers and fluid power equipment. Manufactured from lightweight aviation-grade aluminum alloy via full 5-axis CNC simultaneous machining, it features integrally curved twisted blades and a central threaded hub. The one-piece machining delivers ultra-smooth blade surfaces, precise blade profile accuracy and balanced concentricity, delivering stable high-speed rotation, low wind resistance and efficient fluid compression for long-cycle high-revolution industrial power systems.
- Machining Process: 5-axis simultaneous CNC milling, deburring, precision polishing, dynamic balancing optional
- Material: Aviation Grade Aluminum Alloy (6061 / 7075 customizable)
- Accuracy: ±0.005 mm
- Surface Finish: Fine machined matte finish, mirror polishing optional
- Features: Lightweight, high tensile strength, low air resistance, excellent dynamic balance, high rotational speed resistance

Core Advantages
- Ultra-Light High-Strength Alloy: Aviation aluminum alloy features low density to greatly reduce rotational inertia, allowing stable ultra-high-speed operation, while maintaining strong structural rigidity to resist blade deformation under high air pressure.
- Integrated 5-Axis One-Piece Machining: Twisted 3D curved blades and hub are fully formed in a single 5-axis machining cycle, no blade welding or assembly gaps, eliminating air leakage points and boosting fluid compression efficiency.
- High Precision Aerodynamic Blade Profile: 5-axis simultaneous milling reproduces complex curved blade outlines with micron-level accuracy, paired with optional mirror polishing to cut airflow friction loss and raise overall equipment energy efficiency.
- Excellent Rotational Stability: Post-machining dynamic balancing treatment offsets mass deviation across all blades, effectively suppressing vibration and noise during continuous high-speed rotation, extending bearing and impeller service life.
- Full Custom Aerodynamic Design: Custom blade quantity, twisted curvature, hub thread specifications, overall diameter and flow channel profiles available to match the aerodynamic parameters of your turbo, blower or compressor equipment.
