#duralumin
- Aldural — The commercial or technical name of a special metallic alloy based on aluminum, copper, and magnesium, similar to duralumin, used in the aircraft and machinery industries due to its low weight and exceptional mechanical strength. Structurally, this material undergoes artificial aging heat treatments to optimize its elastic properties and surface hardness.
- Avional — A high-strength structural aluminum alloy, having copper, magnesium, and manganese as its main alloying elements, widely used in the aeronautical and aerospace industries. This metallic material is characterized by a low density, excellent mechanical properties similar to mild steel after hardening heat treatment, and optimal resistance to structural fatigue, making it ideal for airplane fuselages and components.
