Stuttgart, September 2008–MAHLE has developed new valve alloys with significant reductions in nickel content and an excellent price-performance ratio. The new alloys thus allow cost savings of more than 30 percent in some cases.

MAHLE will complete extensive component and engine tests, as well as the release of the new generation of alloys, by the end of 2008. Because the world market price for nickel is continuously increasing, the significantly reduced nickel content in the alloys has a very positive effect on the costs. The new generation of alloys still reliably meets the continually increasing temperature, strength, and corrosion requirements of modern, high-performance engines.

Altogether, MAHLE anticipates having four new alloy variants, optimally adapted to the requirements of engine manufacturers, ready by the end of 2008. The MAHLE research and development center in Stuttgart is working closely with customers and suppliers of valve steels, as well as with research centers.

The MAHLE Group is one of the 30 largest companies in the automotive supply industry worldwide. As a leading manufacturer of components and systems for the combustion engine and related products, MAHLE ranks among the top 3 systems suppliers for piston systems, cylinder components, valve train systems, air management systems, and liquid management systems. MAHLE employs around 48,000 people at 110 production plants and eight research and development centers. In 2007, MAHLE achieved sales of over EUR 5 billion (USD 7.5 billion).
