Robert Aluminium stands out as a top manufacturer and supplier of Aluminium 7050 Round Bars in Pulau Ujong, Singapore. They specialize in high-strength, precision-engineered aluminium products tailored for aerospace, defense, automotive, and industrial uses. Aluminium 7050 is a heat-treatable, high-performance alloy celebrated for its outstanding stress corrosion resistance, fatigue strength, and dimensional stability. These round bars are not only lightweight and durable but also crafted with precision for structural, mechanical, and high-performance engineering needs. Robert Aluminium is committed to upholding international quality standards, ensuring that their Aluminium 7050 Round Bars are reliable, cost-effective, and built to last even in tough conditions.
Aluminium 7050 Round Bars are made from a blend of aluminium with zinc (6.2–6.7%), magnesium (2.0–2.6%), copper (2.0–2.6%), along with small amounts of chromium and other trace elements. This unique composition gives them impressive tensile strength ranging from 503 to 540 MPa, yield strength between 435 and 480 MPa, and a Brinell hardness of about 150 HB. These heat-treatable bars are incredibly durable, offering excellent resistance to stress corrosion cracking, fatigue, and deformation. Lightweight yet strong, Aluminium 7050 Round Bars maintain exceptional dimensional stability, making them ideal for aerospace, defense, automotive, marine, and high-performance industrial applications that demand mechanical reliability.
