Maung Aluminium is a reputable manufacturer and supplier of Aluminium 7050 Round Bars in Naypyidaw, Myanmar, providing top-quality products designed for high-performance applications. Known for their exceptional strength, corrosion resistance, and excellent machinability, Aluminium 7050 Round Bars are ideal for aerospace and demanding structural uses such as aircraft components, landing gear, and other critical parts. These bars meet stringent aerospace standards, ensuring safety and reliability in the most challenging environments. We are committed to delivering quality products that meet the needs of industries requiring robust materials.
UNS A97050 Round Bars are composed of approximately 1.6–2.1% Zinc (Zn), 2.0–2.6% Magnesium (Mg), 0.20–0.40% Copper (Cu), 0.05–0.20% Chromium (Cr), 0.10–0.30% Manganese (Mn), and the remainder Aluminium (Al). These bars exhibit high strength due to their age-hardening T7451 temper, with a tensile strength of around 510–570 MPa (74,000–83,000 psi), yield strength of approximately 420 MPa (61,000 psi), and elongation of 10–12%. They also have a Brinell hardness of about 150 HB and a density of 2.81 g/cm³. Aluminium 7050 Round Bars are renowned for their excellent mechanical properties, making them ideal for aerospace and heavy-duty structural applications.
