**Quyen Aluminium**, a top-notch manufacturer and supplier located in Da Nang, Vietnam, proudly presents high-quality **Aluminium 1070 Round Bars** tailored for industries that demand exceptional corrosion resistance, outstanding thermal and electrical conductivity, and remarkable workability. Alloy 1070 is recognized as a commercially pure aluminium grade (with a minimum of 99.7% aluminium) celebrated for its lightweight nature, smooth finish, and versatility in various fabrication processes. Our round bars are produced with precise diameters, consistent mechanical properties, and excellent surface quality, ensuring reliable performance across a wide range of industrial and commercial applications.
**Aluminium 1070 Round Bars** are primarily made of high-purity aluminium (≥99.7%) with small amounts of silicon, iron, copper, and other trace elements. This unique composition grants them exceptional corrosion resistance in both atmospheric and chemical environments, along with excellent ductility and good welding and forming characteristics. Although they are non-heat-treatable, the alloy can be strengthened through cold working, making it perfect for bending, machining, and custom fabrication without sacrificing its integrity.
