The following is an analysis of the part from the perspectives of material, structure, function, and manufacturing process:

 一、Material

From the metallic texture, lightweight characteristics, and precision machining marks, the material is identified as aluminum alloy  TC4. This type of material has high strength and low density, combined with excellent machinability, making it a common material for impeller components in aerospace and high-end power equipment.

二、Structure and Function

This part is a complex impeller structure with radially distributed blades, which point to its core function of "fluid power transmission":

- The curved shape and arrangement angle of the blades are used to efficiently guide fluid (gas or liquid) and convert kinetic energy into mechanical energy;

- The central shaft hole connects to the power shaft to transmit torque;- The overall symmetrical structure and lightweight design reduce inertial loads during operation and enhance power transmission efficiency.

三、Manufacturing Process

The machining process demonstrates extremely high precision requirements:

- Five-axis CNC machining: The complex curved surfaces of the blades are formed through multi-axis CNC milling, ensuring high-precision dimensional tolerances of ≤0.02mm for blade profile and spacing;

- Surface treatment: The aluminum alloy surface remains in its original color after milling, with high surface finish (Ra ≤ 1.6μm) to reduce fluid resistance;

四、Application Scenario

Considering the structure's "fluid power transmission and high-precision curved surface" characteristics, the part is used in turbochargers (aircraft engines), performing the core role of "converting fluid kinetic energy into mechanical power" and ensuring the high efficiency and stable operation of the power system.
