Characteristic features of aluminum Special measures
Corrosion (ageing) in damp environments. Store aluminum parts in a dry place.
Contact corrosion in event of contact e.g. with steel parts. Always store aluminum parts separately or in isolation from steel parts.
Susceptibility to paint infiltration. Do not damage protective surface layer since this would cause oxidation.
Failure to comply with this requirement would result in more painting work.
