CNC Aluminium Alloy Scooter Wheel

1. Precision Engineering:
- Computer numerical control (CNC) machining ensures micron-level dimensional accuracy (±0.01mm)
- True concentricity with runout <0.05mm for vibration-free rolling
- Customizable hub designs with spline or hexagonal drive systems

2. Advanced Material Properties:
- Aerospace-grade 6061-T6 or 7075 aluminum alloy
- Yield strength: 240-500MPa (varies by alloy)
- Rockwell hardness: HRB 60-95 (pre-anodization)
- Density: 2.7g/cm³ (45% lighter than steel alternatives)

3. Surface Treatment:
- Type III hard anodizing (25-50μm thickness)
- Microhardness: 400-600HV on surface layer
- Pore size: 10-20nm for optimal lubricant retention
- Available in MIL-A-8625 Type II/III certified finishes

4. Performance Geometry:
- Optimized contact patch width (typically 30-45mm)
- Recessed bearing seats with <2μm surface finish
- Dynamic balance weights integrated into design

1. Durability:
- 8-10x longer service life than polyurethane wheels
- Zero deformation under load (up to 300kg radial force)
- Abrasion resistance: <0.1mm wear per 100km of use

2. Performance Benefits:
- 15-20% reduction in rotational inertia
- Consistent coefficient of friction (μ=0.35-0.45)
- Heat dissipation rate: 150-200W/m²K
- No speed wobble at >80km/h due to gyroscopic stability

3. Maintenance Benefits:
- Chemical resistance (pH 4-9 compatible)
- Self-cleaning surface properties
- Bearing replacement cycles extended 3x

4. Technical Superiority:
- 30% better energy transfer than composite wheels
- Noise reduction: <65dB at 40km/h
- Temperature stability: -40°C to +150°C operational range
