Quyen Aluminium, based in Da Nang, Vietnam, is your go-to source for top-notch Aluminium 7075 Flat Bars. These bars are celebrated for their remarkable strength, impressive fatigue resistance, and solid machinability. Crafted with care under strict quality standards, they meet international specifications and cater to a variety of industries, including aerospace, defense, automotive, marine, and industrial engineering. Quyen Aluminium is committed to providing reliable solutions for structural, precision, and high-stress applications. With a strong emphasis on durability, consistency, and timely delivery, their Aluminium 7075 Flat Bars are trusted both locally and globally for high-performance, long-lasting use.
These flat bars are primarily made from an aluminium alloy that includes zinc (5.1%–6.1%), magnesium (2.1%–2.9%), and copper (1.2%–2.0%), along with small amounts of chromium and other elements. This high-strength blend gives them outstanding mechanical properties, such as superior tensile and yield strength, excellent fatigue resistance, and good toughness. While they may not be as corrosion-resistant as some other aluminium grades, they strike a great balance between strength and weight, making them perfect for demanding structural components.
