1.11 Aluminium
1.11.2 Corrosion protection
To prevent contact corrosion, only surface-coated fastener
elements - bolts, nuts, washers, blind rivets, self-piercing
rivets, etc. - are used in the manufacture of the vehicle. These
components are tested for their compatibility with aluminium.
New fastener elements must always be used when carrying
out repairs. Screws may not be used as the friction generated
during tightening reduces the thickness of the coating. Grinding
work on steel components (blind rivets, self-piercing rivets,
bolts) is not permitted.
The dust produced by grinding contains minute steel particles
which would damage the aluminium.
The following work is required after an accident repair:
• Painting, from primer right through to glaze
• Post-treatment (sealing) of edges; material used:
1-component polyurethane-based permanently-elastic
body sealing compound and 1-component polymer-based
permanently-elastic body sealing compound
• Corrosion protection treatment for the underbody
• Post-treatment of cavities with cavity protection agents.

1.11.3 Screw connections
Caution!
Bolts must not be reused. Friction produced during
tightening reduces the thickness of the coating.
Mechanical components and bodywork elements are fastened
to parts of the body with rivets (with blind rivets and self-piercing
rivets), screws applied to threaded rivets and screws applied
to threads cut directly into the aluminium. To prevent damage
to the threads, please observe the maximum torque values.
1.11.4 Lightweight construction
To reduce vehicle weight, the entire(*) vehicle body has been
manufactured from aluminium components. The specific
weight of aluminium is just 2.70 kg/dm
3
, whereas that of steel
is 7.85 kg/dm
3
. As a result, a considerably higher strength
compared with a unitary construction steel body can be
achieved.
