TRIMET presents new alloy variant for use in automotive manufacturing

The aluminum specialist TRIMET produces around 100,000 tons of wires annually for a wide range of applications.The aluminum specialist TRIMET produces around 100,000 tons of wires annually for a wide range of applications.

Oct 18, 2016 | At the Aluminium 2016, TRIMET Aluminum SE will be presenting itself with a broad range of products and services. At the aluminum industry’s leading trade fair, the materials specialist will show a new variant of the alloy EN AW-6082, which features a high resistance to intergranular corrosion. It opens up new application areas for aluminum wires in automotive manufacturing.

The new material combines the proven mechanical and dynamic properties of the alloy type EN AW-6082 with a significantly improved corrosion resistance. “Many potential applications for mechanical wires place high demands on the corrosion behavior of the materials. The impact of road salt in combination with a humid atmosphere in winter, for example, puts a strain on automobile components, which quickly leads to intergranular attacks. With our new variant, we can largely eliminate intergranular corrosion,” explains Luigi Mattina, member of the Management Board of TRIMET Aluminum SE.

At the international industry forum, TRIMET will be introducing the new alloy variant for the first time as part of the Aluminium 2016 Conference. Potential applications include sensors in automotive rims, for example, which permanently monitor tire pressure while traveling.

The percentage of aluminum components used in automobile manufacturing has been rising for years. Wires made of the light metal aluminum are used in both electrically conductive and mechanical applications. The most important growth areas for mechanical applications are cold-formed components, including screws, nuts, bolts and rivets. TRIMET offers its customers a wide range of corresponding wires in the AlCu, AlMg and AlMgSi categories.

The aluminum alloy EN AW-6056 has also proved its worth for the corrosive and thermal loads that occur in automobiles. Screws with a tensile strength of around 400 MPa can be produced from this alloy with good temperature stability under long-term exposure.

TRIMET’s wire production is concentrated at its two French locations in Saint-Jean-de-Maurienne and Castelsarrasin. With four casting and rolling plants and associated heat treatment furnaces, the family-run company fulfills a full range of customer requirements in terms of cross-sections, processing and alloys.

Aluminium 2016 from November 29 to December 1, 2016 in Düsseldorf – TRIMET is looking forward to your visit in hall 11 at booth E20.
