METALS USED IN THE AUTOMOTIVE INDUSTRY

Posted August 24th 2015

Everyone knows that the automotive industry uses metal. The frames of our vehicles are metal, metal is used to make the majority of the mechanical components, and is even used in the electronics. But what kinds of metals are used in the automotive industry?

In order for a metal to be considered appropriate for use in the automotive industry, it has to meet at least some of the following criteria:

· Price – It is possible to find very lightweight metals that are also extremely strong. These metals, however, are generally also very expensive. A car manufacturer has to carefully weigh the costs and benefits of picking a metal, and price is a big factor.

· Safety – The primary concern of the automotive industry is to build cars that are both affordable and safe. A rigid metal is not necessarily the best choice, since the purpose of a car should be to protect the driver, and a frame made from rigid metal would transfer the force of the impact to the driver and passengers. Energy absorption, then, is another factor used to rate the worthiness of a metal for the automotive industry.

Steel, aluminium, and magnesium are all common metals used in the automotive industry, as all three meet the criteria stated above. Rarely however do these metals display all the right properties when in their pure state, and often need additional elements to make alloys that truly deliver what the car makers require.

William Rowland supplies the nickel, chrome, cobalt, and other alloying elements that foundries need in order to make metals that are strong enough, light enough, and cheap enough for the automotive industry to use. These metals are the major components of the alloys that are used to cast and form the vast majority of car parts today.
