名称：Alcotec 7075 Alloy
ALLOY CHARACTERISTICS ALLOY 7075 WAS ORIGINALLY DEVELOPED IN 1943. THE HIGH STRENGTH OF THE 7XXX SERIES OF ALLOYS WAS DESIRABLE FOR AIRCRAFT APPLICATIONS, 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 CONSIDERATIONS. ALLOYS 7075 AND 7175 ARE NOT CONSIDERED 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 QUESTIONS CONCERNING THE WELDING OF THESE ALLOYS. ALLOY 7175 IS TYPICALLY UTILIZED IN APPLICATIONS WHERE IMPROVED FORMABILITY AND TOUGHNESS ARE DESIRED.
