Aluminium screws for magnesium components

02 December 2010

Alufast type 6056 aluminium screws from Arnold Umformtechnik are suitable for joining magnesium components subject to thermal stress and corrosion. The mechanical properties of the screws are practically stable under long-term stress at temperatures up to 150°C, while brief excursions to 180 °C can be tolerated. Alufast screws can be used untreated in combination with commonly used magnesium casting alloys, such as Az91 HP.

And with a thermal expansion coefficient similar to that of magnesium, Alufast screws exhibit significantly less loss of clamping force with temperature cycling than conventional steel screws. As they weigh only one-third as much as equivalent steel screws, weight savings in a transmission application with 20 screws can be as much as 340 grams. Even greater weight savings can be achieved because the screw length can be reduced considerably without compromising joint quality.
