The hydraulic motor housings are generally manufactured by casting process, and the main materials are cast iron and cast steel. Both materials have their own advantages and disadvantages.

The advantages of cast iron hydraulic motor housing:
1. High hardness, good effect on resisting impact and wear.
2. Low cost, relatively cheap price.
3. Easy to process and stable processing performance.

The disadvantages of cast iron hydraulic motor housing:
1. Low rigidity, easy to fatigue deformation and cracking.
2. Low tensile strength and elongation.
3. Relatively low corrosion resistance, easy to rust in humid and corrosive environment.

The advantages of cast steel hydraulic motor housing:
1. High strength, more resistant to impact and wear.
2. Good rigidity, not prone to fatigue deformation and cracking.
3. High temperature and corrosion resistance, suitable for harsh environments.

The disadvantages of cast steel hydraulic motor housing:
1. The cost is high.
2. The processing and production are difficult and require specialized equipment.
