5052-h32 aluminum alloy for fan blades
Fan blades, as critical components in ventilation systems, demand materials that balance strength, corrosion resistance, and weight. 5052 aluminum alloy—particularly the 5052-H32 temper—excels in these aspects, making it a top choice for industrial fans, HVAC units, and electric vehicle cooling systems.
I. Key Advantages of 5052-H32 Aluminum Sheets
-
Strength-to-Weight Ratio
With 2.2%-2.8% Mg content, 5052-H32 offers tensile strength ≥195MPa and yield strength ≥120MPa while maintaining a low density (2.68g/cm³), enabling energy-efficient designs. -
Corrosion Resistance
The alloy’s self-forming oxide layer resists salt spray, humidity, and chemical exposure. Tests show ≤0.5% corrosion area after 1000h in 5% NaCl solution at 35°C, ideal for marine or industrial environments. -
Formability & Weldability
The H32 temper (1/4 hard) allows deep drawing (minimum bend radius: 1.5×thickness) and retains ≥90% post-weld strength, compatible with TIG/MIG processes.
II. Typical Applications
-
Industrial Centrifugal Fans
In steel mills or cement plants, 5052 blades withstand 120°C operating temperatures and 3× longer lifespans than steel via anodized coatings. -
HVAC Axial Fans
Thicknesses from 1.2mm to 3.0mm enable laser-cut blades with ≤55dB noise levels, meeting residential and commercial standards. -
EV Thermal Management
0.5mm ultra-thin sheets provide 138W/(m·K) thermal conductivity for battery cooling modules, combining heat dissipation and structural integrity.
III. Selection Guide for 5052-H32 Sheets
-
Certifications
Verify compliance with ASTM B209/EN 485 standards, ensuring chemical composition (Si≤0.4%, Fe≤0.4%) and mechanical properties. -
Surface Treatments
- General Use: Sandblasting (Ra3.2μm)
- Marine Use: 3-layer polyester coating (1000h+ salt spray resistance)
- Food Grade: FDA-approved anodizing
-
Customization
Benefit from slitting, shearing, and bending services with MOQs as low as 500kg and 7-15 day lead times.
Conclusion
5052-H32 aluminum redefines fan blade performance through its triad of strength, corrosion resistance, and lightweight design. Optimized material selection can boost energy efficiency by 15-20% while reducing maintenance costs by 30%. Contact our experts for tailored solutions and technical support.
