A "metal part" refers to a component made from various types of metals, such as steel, aluminum, or copper. These parts are commonly used in a wide range of applications, including machinery, vehicles, and electronics. Their durability and strength make them essential in construction and manufacturing processes. Metal parts can be produced through various methods, including casting, forging, and machining. Each method has its advantages, depending on the desired shape, size, and properties of the final product. Proper treatment and finishing processes, such as plating or coating, can enhance their performance and resistance to corrosion.
