Aluminum Alloy Impeller

Lightweight and High-Performance Material Advantage

An Aluminum Alloy Impeller offers significant weight reduction compared with steel or cast iron impellers, which improves pump efficiency and reduces motor energy consumption.

The typical materials used, such as ADC12 or 70-series aluminum alloys, provide:

Low density for reduced rotational inertia

Good thermal conductivity for efficient heat dissipation

Adequate strength for moderate-pressure applications

Resistance to corrosion in mild aqueous environments

Manufacturing Challenges & Precision Requirements

Dimensional Sensitivity

Aluminum alloys are prone to deformation during machining due to low rigidity and thermal expansion. High-precision impellers require:

Internal bore tolerance ≤ 0.01 mm

Bore roundness ≤ 0.005 mm

Consistent vane geometry to maintain hydraulic efficiency

Environmental Control

Workshop temperature should be maintained between 20–25°C

Humidity control is essential to prevent surface oxidation and microcracking

Cutting fluids and tool selection are optimized to minimize deformation and stress
