With a commitment to excellence, Thongsa Aluminium provides robust, corrosion-resistant, and lightweight aluminium products designed for optimal performance in demanding applications. Their dedication to quality, reliability, and customer satisfaction makes them a trusted partner in the aluminium manufacturing industry.
Aluminium 7075 flanges are made from a high-strength, heat-treated alloy primarily composed of aluminium, zinc (5.1–6.1%), magnesium (2.1–2.9%), copper (1.2–2.0%), and smaller amounts of chromium, silicon, and manganese. Known for its exceptional strength-to-weight ratio, it is one of the strongest aluminium alloys. The mechanical properties of Aluminium 7075 include high tensile strength (up to 700 MPa), excellent fatigue resistance, and good machinability. These flanges are corrosion-resistant, making them ideal for aerospace, military, and high-performance engineering applications where durability and precision are essential.
