ALLOY CHARACTERISTICS ALLOY 7075 WAS ORIGINALLY DEVELOPED IN 1943. THE HIGH STRENGTH OF THE 7XXX SERIES OF ALLOYS WAS DESIRABLE FOR AIRCRAFT APPLICATI***, HOWEVER, IT WAS NOT UNTIL THE DEVELOPMENT OF THE – T73 TEMPER THAT THE ALLOY BECAME COMMERCIALLY VIABLE. THE COMBINATION OF HIGH STRENGTH, RESISTANCE TO STRESS CORROSION CRACKING (SCC) AND HIGH FRACTURE TOUGHNESS HAS MADE THE ALLOY A MAJOR FACTOR IN THE AEROSPACE INDUSTRY. THE ALLOY IS OFTEN UTILIZED IN COMPRESSIVE LOAD DESIGN C***IDERATI***. ALLOYS 7075 AND 7175 ARE NOT C***IDERED TO BE WELDABLE DUE TO EUTECTIC MELTING AND INTERGRANULAR CORROSION PROBLEMS IN THE HAZ DURING SERVICE AFTER WELDING. CONTACT ALCOTEC WIRE CORPORATION TO ANSWER ANY QUESTI*** CONCERNING THE WELDING OF THESE ALLOYS. ALLOY 7175 IS TYPICALLY UTILIZED IN APPLICATI*** WHERE IMPROVED FORMABILITY AND TOUGHNESS ARE DESIRED.
