Automotive forgings can be divided into many types, common ones include: Crankshaft: One of the parts of the automotive engine that is responsible for converting piston motion into rotary motion. Connecting rod: The part that connects the crankshaft to the piston and transfers the force generated by the piston to the crankshaft. Gear shaft: A component used to transfer power and adjust speed, commonly found in transmissions and transmission systems. Suspension arm: A component used to support and connect the body to the suspension system. Brake roller: used as a component of the brake system to complete the braking function together with the brake pads. Housing: Components used to support and position rotating components, such as steering housings and engine main housings. Exhaust pipe flange: Part used to connect the engine exhaust system to the exhaust pipe. Transmission latch: A component used to control the position and operation of transmission gears. When choosing materials, automotive forgings need to consider the following factors: strength and stiffness: Automotive forgings need to have sufficient strength and stiffness to withstand the power and load of the car when working. Common material choices include carbon steel, alloy steel and stainless steel. Wear resistance: Automobile forgings need to have good wear resistance to ensure that long-term use is not easy to wear. Materials with higher hardness and wear layers are usually selected, such as hardened steel and carburized steel. Corrosion resistance: the car may be exposed to different corrosive media in different working environments, so the forgings need to have a certain corrosion resistance, usually choose materials with good corrosion resistance, such as stainless steel and nickel-based alloys. Cost and machinability: The manufacturing cost and machinability of automotive forgings are also factors that need to be considered when selecting materials. In general, materials that are economical, practical and easy to process are selected according to specific needs. In short, the material selection of automobile forgings needs to comprehensively consider factors such as strength, stiffness, wear resistance, corrosion resistance, cost and machinability to ensure that the forgings have good performance and reliability under the working conditions of the automobile.
