7000 series aluminum is Al-Mg-Si-Cu Alloy,including 7075 T651 T7351 aluminum pipe,7072 aluminum pipe,7072-T7451 aluminium pipe,This alloy is precipitation hardened to very high strength levels. Alloy 7000 is used in airframe structures and other highly stressed components.
7075-T651 Aluminum plate is an excellent candidate for most processing techniques and offers moderate corrosion resistance. With one of the highest strength to weight ratios for heat treatable alloys, it’s a lightweight material with a semi-smooth surface and a dull mill finish. Commonly machined to end user specifications, typical applications include aircrafts, marine, motor sports, and commercial grade parts.Key Words: Aluminium 7075-T6; Aluminium 7075-T651, UNS A97075; ISO AlZn5.5MgCu;Aluminium 7075-T6; Aluminium 7075-T651; AA7075-T6

Industry Applications
The 7000 series aluminum alloys are usable in a variety of applications. The light weight and toughness characteristics of grade 7075 are valued highly by manufacturers and end users. As a strong, machinable aluminum alloy, it is highly used in the automotive, aircraft and aerospace industries. Highly stressed parts, such as gears, fuse parts, structural components, and bows are often comprised of 7075 aluminum alloy. You can purchase high quality 7075-T651 aluminum from our inventory at Howard Precision Metals.
Machining and Welding Operations
Grade 7075 is easy to work with and machinable. General welding is not recommended with 7075 aluminum alloy. However, you may achieve desirable results when applying resistance welding to the alloy. The application of arc or gas welding may lower the alloy’s natural anti-corrosion properties.
