Robert Aluminium stands out as a top manufacturer and supplier of Aluminium 7050 Circles in Pulau Ujong, Singapore. They specialize in high-performance aluminium products tailored for aerospace, automotive, and industrial uses. Aluminium 7050 is a robust, heat-treatable alloy known for its impressive resistance to stress corrosion, making it perfect for critical structural components. These circles are meticulously engineered to ensure exceptional dimensional stability, strength, and durability, even in extreme conditions. With a commitment to strict quality control and international standards, Robert Aluminium delivers reliable, cost-effective Aluminium 7050 Circles to clients in Singapore and around the globe, meeting the demands for strength, corrosion resistance, and lightweight properties.
Aluminium 7050 Circles are mainly made up of aluminium, along with zinc (6.2–6.7%), magnesium (2.0–2.6%), copper (2.0–2.6%), and trace amounts of chromium and other elements. This unique blend gives the alloy impressive tensile strength, typically ranging from 503 to 540 MPa, and a yield strength between 435 and 480 MPa, with a Brinell hardness of about 150 HB. It’s heat-treatable and boasts excellent resistance to stress corrosion cracking, fatigue strength, and fracture toughness. Aluminium 7050 Circles also maintain outstanding dimensional stability during machining and forming, making them ideal for critical aerospace, defense, and high-performance engineering applications that require lightweight yet incredibly strong components.
