Is the trunk of the Corolla made of iron?

Corolla's trunk is made of plastic. Methods to open the trunk: Use the trunk button or lever on the door, press the rear lid button, or use the car key. Different car manufacturers and models have different methods for opening the trunk. Introduction to the car trunk: The trunk of a car is the space for storing spare items and carrying goods. Since small cars can be categorized as hatchbacks or sedans, the size of the trunk varies accordingly. Generally, the trunk contains the car's spare tire, first aid kit, onboard tool kit, warning triangle, fire extinguisher, car refrigerator, and the emergency release cable for the fuel tank cap. In some high-end models, the starter battery is also located in the trunk.
As an automotive enthusiast with some knowledge of car manufacturing, I've noticed that the trunk lids of the Corolla are mostly made of steel, not pure iron—the term 'iron' is too general. Automotive components typically use steel alloys, such as galvanized steel. The choice of steel materials is primarily to balance strength and cost. As Toyota's entry-level model, the Corolla prioritizes affordability and practicality, where steel is significantly cheaper than aluminum and easier to mass-produce, while also enhancing crash safety—the trunk lid can absorb impact energy to protect passengers. Although modern Corollas focus on lightweighting, the trunk section remains largely unchanged, with weight reduction strategies applied to other areas like the roof or door panels, which may incorporate aluminum. Of course, when buying a used car, rust spots can be a common issue, so regular cleaning and applying anti-rust oil for maintenance is advisable, especially in humid regions where steel components are prone to corrosion. This design logic is also reflected in similar models, such as the Honda Civic, where steel is prioritized to keep costs low.
