Aluminum 7050 circle is a high-strength, heat-treatable alloy used primarily in aerospace applications. Its composition is approximately 6.2-6.6% zinc (Zn), 2.0-2.6% magnesium (Mg), 1.9-2.6% copper (Cu), 0.12-0.18% Zirconium (Zr), Chromium ( Cr), Manganese (Mn), Silicon (Si). This alloy provides exceptional resistance to stress corrosion cracking and greater strength than 7075, especially in hard parts. It is known for its high strength and weight ratio, excellent fatigue resistance and mechanical quality, making it suitable for critical aerospace system applications where durability is required.
