Iron
Steel
The ferrous metal commonly used to make car bodies is steel. Steel is chosen for its strength, durability, and formability, making it ideal for providing structure and protection in automotive applications.
Sheet metal used on older car bodies typically ranges from a gauge of 16 to 18. Sheet metal used on the auto body of new vehicles and when aftermarket body work is performed tends to be between 20 and 22 gauge.
Too expensive
its parts it too costly . thick metal is not welable. its machines are very cotly Specialist machines can be expensive, but can make many welds a minute very cheaply, as used on car bodies. Thin metal can be welded to thick, but as the objects get larger, much more electrical current is required, and this gives problems with electrode contact and burning under the electrode
Strong and lighweight metal used for contrruction of airplanes.
it is because they are a malluable, waterproof, good conductor of heat metal.
Strength, cheapness and the ability to be easily formed or "moulded". However, increasingly, a lot of car bodies incorporate fibre glass, plastics, carbon fiber and other composite materials.
No, fiberglass is not metal. It is a composite material typically made of glass fibers embedded in resin. It is lightweight, durable, and commonly used in various applications such as insulation, boats, and car bodies.
How thick thick the metal is.
they slither slowly cause of their thick bodies
