High-performance tungsten-based materials make casting processes more cost-effective and improve quality

摘要

Fire cracks and corrosion are the most common types of casting tool damage in light metal casting. Usually such damage reduces product quality, which may worsen even further under some circumstances due to adhesion or inadequate heat dissipation. With its Triamet A product family, a tungsten-based heavy metal alloy, Bayerische Metallwerke GmbH in Dachau, Germany, offers an innovative and ecological alternative that avoids these problems. Thanks to a tungsten content of up to 98p, the Triamet A materials withstand the stresses of frequent temperature changes in the casting process over the long term and set themselves apart with high corrosion resistance compared to aluminium and copper alloys. The various tungsten alloys were presented at this year's ALUMINIUM 2016 trade fair in Duesseldorf.
