Duralumin

Description

Originally a trademark for an aluminum alloy that was developed by Alfred Wilm in Germany in 1906. Duralumin is composed of Aluminum (90%) alloyed with Copper (about 4%), Manganese (0.25-1.0%), and Magnesium (0.5-1.0%) along with trace amounts of Iron and Silicon. The age or heat hardened alloy is more resistant to corrosion than pure aluminum. The lightweight Duralumin was used for zeppelin airframes and parts in other early aircraft.
