Trimet: new alloy variant for use in automobile manufacturing
At ALUMINIUM 2016, Trimet Aluminium in Essen is introducing a new variant of the EN AW-6082 alloy that offers high resistance to intergranular corrosion. It opens up new application potential for aluminium wiring in automobile manufacturing.
The new material combines the proven mechanical and dynamic properties of the EN AW-6082 alloy with considerably enhanced corrosion resistance. "Many potential applications for mechanical wires place high demands on corrosion behaviour. For example, the impact of road salt in combination with wet conditions during winter is a big problem for car components, quickly producing the feared phenomenon of intergranular attack. With our new variant, intergranular corrosion can be largely ruled out," explains Luigi Mattina, member of Trimet Aluminium SE's management board.
As part of the Aluminium 2016 Conference, Trimet will be introducing the new alloy variant for the first time at the international industry forum. Potential applications include, for example, sensors in car wheel rims that constantly monitor tyre pressure while driving.
For years, the proportion of aluminium components has been rising in automobile manufacturing. For example, wire made of this light metal is put to use in electrical-conducting and mechanical applications. Here, cold-formed components, such as screws, nuts, bolts and rivets represent an important growth area for mechanical applications. Trimet offers its customers a wide spectrum of such wires in the categories of AlCu, AlMg and AlMgSi.
