What is the body material of BMW X 1?
The body material of BMW X 1 is aluminum. Aluminum materials for automobile mainly include aluminum plate, extruded material, cast aluminum and forged aluminum. Aluminum plates were first used in hood outer panels, front fenders and roof, and later used in doors and trunk lids.

Other applications are car body structure, space frame, outer cover and wheels, such as car body, air conditioning equipment, engine cylinder block, cylinder head, suspension bracket, seat and so on. In addition, aluminum alloy is also widely used in automobile electrical appliances and wires, and aluminum-based composites can also be used in brake pads and some high-performance structural parts. Automobile body materials can be roughly divided into two categories: 1, metal materials: heavy metal materials such as steel plate and cast iron; Aluminum, magnesium, titanium and other light metals and their alloy materials, foam metals and other materials; 2. Non-metallic materials: engineering plastics, fibers, resins, glass, rubber, non-metallic foam materials, non-metallic composite materials, etc. With the development of automobile technology, in addition to metallic materials and nonmetallic materials, composite materials and nano-materials will also be widely used in the future.
