Aluminum Alloy Materials in Side Channel Blowers

Side Channel Blowers (also known as regenerative blowers or ring blowers) are widely used in pneumatic conveying, vacuum suction, wastewater treatment, medical equipment, and other applications.
Due to their compact design, oil-free operation, and low noise levels, the choice of material is critical. Aluminum alloys are the preferred choice because of their lightweight properties, corrosion resistance, and excellent mechanical performance.

This article will introduce the aluminum alloys commonly used in Side Channel Blowers, analyzing their physical properties, advantages, and suitable applications to help users better understand material selection.

 

Key Aluminum Alloys Used in Side Channel Blowers

The core components of Side Channel Blowers (such as impellers, housings, and end covers) are typically made from the following aluminum alloys:

ADC12 (Die-Cast Aluminum Alloy)

• Composition: High silicon (Si 10.5-12%), copper (Cu 1.5-3.5%), excellent fluidity for precision die-casting.

• Advantages:

  • Superior Castability: Enables complex impeller designs with minimal post-processing.

  • Lightweight: Low density (~2.7 g/cm³) reduces overall blower weight.

  • Good Rigidity: Meets strength requirements for side channel blowers.

Key Advantages of Aluminum Alloys in Side Channel Blowers

Compared to traditional cast iron or stainless steel, aluminum alloys offer significant benefits in Side Channel Blowers:

Lightweight & Energy Efficient

• Aluminum's density (~2.7 g/cm³) is 1/3 that of steel, reducing rotational inertia and motor load, improving energy efficiency.

Excellent Heat Dissipation

• High thermal conductivity (~200 W/m·K) allows rapid heat dissipation, preventing overheating and prolonging lifespan.

Corrosion Resistance & Longevity

• Aluminum naturally forms a protective oxide layer (Al₂O₃), making it resistant to moisture, chemicals, and oxidation.

Low Noise & High Precision

• Die-cast aluminum impellers ensure excellent dynamic balance, minimizing vibration and noise.

Cost-Effective Manufacturing

• Die-cast alloys (e.g., ADC12) enable high-volume production at lower costs, reducing machining steps.
