What are the materials commonly used in pin shafts and connecting rods?

Pins and connecting rods are commonly used components in mechanical transmissions and are commonly available in the following materials:

Carbon steel: Carbon steel is one of the commonly used materials with good strength and toughness, suitable for applications under general loads and working conditions.

Aluminium alloys: Aluminium alloys have low density, good corrosion resistance and thermal conductivity and are suitable for applications with light loads and high speeds, such as aircraft and automobiles.

Stainless steel: Stainless steel has good corrosion resistance and high temperature resistance for use in wet, corrosive environments, such as marine engineering and food processing equipment, etc.

Alloy steels: Alloy steels have high strength and hardness and are suitable for applications subjected to high loads and high temperature environments, such as engines, hydraulic machinery, etc.

Copper alloys: Copper alloys have good electrical and thermal conductivity and are suitable for applications in high-speed rotating and high-temperature environments, such as motors, generators, etc.
