Aluminum alloy 6069 part II: fracture toughness of 6061-T6 and 6069-T6

This work investigates the fracture toughness of a new high strength aluminum alloy AA 6069. Earlier work reports that this alloy has higher tensile and fatigue strength and corrosion properties than AA 6061. The results of this research reports that the fracture toughness of 6069-T6, similarly, is...

Description
Summary:This work investigates the fracture toughness of a new high strength aluminum alloy AA 6069. Earlier work reports that this alloy has higher tensile and fatigue strength and corrosion properties than AA 6061. The results of this research reports that the fracture toughness of 6069-T6, similarly, is comparable or superior to that of 6061-T6 with identical ingot preparation and subsequent forming procedures.
