Renowned for their exceptional strength, durability, and resistance to corrosion, these products are perfect for applications in aerospace, defense, and other high-stress structural environments. Boikanyo guarantees that all Aluminium 7050 materials adhere to rigorous international standards for mechanical performance and reliability. With a commitment to consistent quality, precise machining, and outstanding durability, Boikanyo’s Aluminium 7050 Plates and Sheets are the go-to choice for critical components where strength, fatigue resistance, and long-lasting integrity are paramount.
Aluminium 7050 Plates and Sheets are crafted from a heat-treatable aluminium-zinc alloy that contains around 5.7–6.7% zinc, 2.0–2.6% magnesium, and 2.0–2.6% copper, along with trace amounts of chromium, manganese, and silicon. This alloy is known for its high strength, impressive stress corrosion resistance, and solid toughness. The typical tensile strength ranges from 470–540 MPa, while the yield strength falls between 390–480 MPa, depending on the temper (usually T7451 or T7651). Elongation rates vary from 7–13%. Aluminium 7050 retains its mechanical properties even in thicker sections and excels in applications that demand strength and stability under extreme conditions.
