The use of aluminium in car making in the United States is apparently on the rise, though steel has the edge with incumbency and price.
The Wall Street Journal reports that the new model Ford F-150 is around 320 kilograms less than the 2009 model, with a large part of the reason being aluminium replacing steel.
Another piece of evidence to support the argument that steel is gaining ground is Alcoa’s New York Stock Exchange price, which is up by four fifths since October.
The high price of oil and increased regulation on emissions are helping drive the demands for lighter weight cars. A light vehicle is typically made up in weight by 70 per cent steel and 10 per cent aluminium, according to the Journal.
Factors holding back the increased adoption of aluminium in cars include the established links between the steel industry and car companies, the familiarity of panel beaters with steel, and the cheapness of auto-grade steel over aluminium.
