Aldural
Definition
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.
