Alufast aluminium screws from Arnold Umformtechnik are suitable for joining magnesium components. With material pairs exposed to thermal stress, they enhance the security of threaded fastener joints, claims the company, and weigh only one-third as much as equivalent steel screws.
Alufast products fulfil stringent requirements for retention of clamping force, thermal stability and weight reduction. These fasteners also exhibit good corrosion characteristics. The mechanical properties of the screws are practically stable under long-term stress at temperatures up to approximately 150°C, although brief excursions up to approximately 180°C do not pose a risk.
