As customers downsize to smaller vehicles where cost pressures are more intense and profit margins thinner, aluminium’s penetration of the road wheel market is naturally lower than that of lower cost steel.
Aluminium wheels (also known as ‘alloy’) are around 20% lighter than steel wheels but the material and manufacturing costs are considerably higher, making them at least three times more expensive than steel wheels.
just-auto estimates that in North America, about 62% of new passenger cars and light trucks sold in 2006 were equipped with aluminium wheels, up from 55% in 2000.
Aluminium installation rates have increased to this level since the mid-1980s, when it was only 10%.
In Western Europe, just-auto estimates that about one-third of newly registered cars come equipped with aluminium wheels, up from one-quarter in 2000.
Japan is estimated to have a similar aluminium road wheels share to that of Western Europe.
The differential between aluminium and steel wheels in terms of styling capabilities is now seen as much reduced in the industry and that, combined with lower cost, is enhancing the attractiveness of steel wheels.
However, prospects for aluminium in some developing regions that have high steel penetration already – and where overall market growth is high - are more positive as these markets are expected to see an increased use of aluminium. China is also emerging as a heavy user of aluminium wheels.
