Aluminum-based alloy composition and method of making extruded components from aluminum-based alloy compositions

摘要

The present invention involves an aluminum-based alloy composition for vehicle components. The composition consists essentially of between about 0.15 to 0.6% weight silicon to provide recrystallization, between about 0.2 to 0.7% weight iron, between about 0.4 to 0.6% weight copper, between about 1.1 to 1.4% weight manganese, between about 0.15 to 0.3% weight magnesium, between about 0.15 to 0.4% weight zinc, between about 0.1 to 0.15% weight zirconium, and the balance aluminum.
