Cast iron is primarily composed of iron, carbon, and silicon alloy, offering high strength, good toughness, plasticity, and versatility. The casting process involves applying the primary color, frosting the surface, anti-rust treatment, thread alignment, and chassis formation. It can be used to make bookshelves and drying racks, as well as decorative objects, retro lighting, and other handicrafts, suitable for taverns, bars, restaurants, hotels, and even antique homes.
