Different Materials Used for Automobile Production

Automobiles necessitate a wide assortment of raw materials for their manufacturing, including iron, which is converted into steel; aluminium; glass; petroleum products used to make plastics; rubber; and special fibres. First, raw materials are extracted from the earth. Then, a raw material production company processes the raw materials into auto manufacturing materials to be used in the production of automobiles. Those materials are either sold straight to auto manufacturers or to auto parts suppliers.

Several Automobile Parts
Numerous component parts go into producing an automobile. Beyond the large basic building blocks such as engines, transmissions and wheels, there are the interior parts such as instrument panels, seats and HVAC systems, along with all the wiring needed to tie them together. Over time, the materials used to build these various component parts have changed to some extent, but the overall bulk of what goes into automotive manufacturing has generally remained the same.

Steel, produced from mined iron ore, is arguably the most widely used component in auto manufacturing. It accounts for approximately 80% of the overall weight of an average car. Steel is used to build a car's chassis and body, including the roof, body and door panels as well. Technological advances over the years have enabled auto manufacturers to utilise different forms of steel that have fluctuating levels of rigidity.

Oil and gas are the raw material source of the several plastic components in cars. Chemical companies can transform petroleum by-products into plastic. Plastics are the rivals of steel for prominence in auto manufacturing. Altogether, plastic comprises approximately 50% of what goes into the production of a new car. The versatility, durability and lightweight character of plastics make them an ideal material for various parts.

Aluminium, largely due to its malleability and lightweight nature, is being increasingly used in car manufacturing. Aluminium has progressed from accounting for just 2% of the weight of an average car in 1970 to nearly 15% today. Wheels are commonly made of aluminium, and it has replaced steel and iron in the construction of many critical auto parts, such as engine blocks.

Rubber is essential for cars, and the auto industry is essential to the rubber industry. Tires are one of the most important parts of a car. In addition to tires, rubber is also used for making numerous belts, hoses and seals critical to the functioning of a car's engine. Like plastic, rubber is durable and easily moulded into different shapes. In all, the demand for rubber that comes from the auto industry accounts for approximately 80% of the world's total rubber production.

From metals to fibres and other materials, automobile manufacturing uses possibly more raw materials than virtually any other production industry. Since it first developed the assembly line process, the auto industry has always been a leader in innovations in mass production, and its adaptive use of raw materials is an important factor in its success as an industry.
