Lightening the load
An investigation carried out by fastener specialists Arnold
Umformtechnik GmbH found that in a gearbox containing 20
screws, Alufast weighed approximately 350 grams less that the
steel version of the screw.
At the same time the Alufast range scores even more points when
used in corrosive atmospheres where fastener locations are subjected to
particularly high temperature loads. Alufast screws have proven to be of
particular value under thermal loads. The mechanical properties of the
screws remain stable over a long-term period of load, up to a peak
temperature of 150 degrees Celsius.
Designers can use standard head settings when fastening magnesium
components, unlike steel screws, which would require larger head
settings. The screws achieve process reliability, high strength and
expansion characteristics, and also possess excellent anti-corrosion
properties.
Alufast presents an advantage over steel screws by producing greater
residual clamp forces on magnesium fastenings under operational
thermal loads than is possible with steel screws. And the 20 to 50
percent cost saving, compared to steel screws with additional corrosion
protection systems, complete the benefits package.
