7175 aluminum is a high-strength Al-Zn-Mg-Cu alloy used primarily in aircraft primary structure and military applications, offering tensile strengths exceeding 500 MPa with good fatigue resistance and damage tolerance. The alloy exhibits limited corrosion resistance in marine environments and reduced fracture toughness at higher tempers, necessitating careful temper selection and protective coatings for critical applications.
