Sistance, and ductility, making it extensively used in construction, automotive manufacturing, aerospace, tool manufacturing, and many other fields. Steel can be further hardened or tempered through variousteel is a metal material composed of iron, carbon, and other alloying elements. It exhibits high strength, corrosion res heat treatment methods to adjust its hardness and strength.

The main components of a hydraulic pump include the pump body, drive mechanism, inlet and outlet valves, and hydraulic oil reservoir. The pump body, typically made of metal, houses a series of gears, blades, or pistons. The drive mechanism, which can be an electric motor, engine, or manual operating device, provides the mechanical power to drive the pump body. The inlet and outlet valves control the flow direction and pressure of the liquid. The hydraulic oil reservoir stores the hydraulic oil and is connected to the pump body through pipelines.

When choosing between iron, steel, and aluminum alloy as materials, specific application requirements such as desired strength, weight, corrosion resistance, and cost need to be considered. Each material has its unique characteristics and suitable applications, so making the appropriate selection based on specific circumstances is crucial.
