7XXX Aluminum-Zinc Alloy Sheet & Plate

7xxx aluminum alloys are another commonly used alloy, with a wide variety of types. They contain zinc and magnesium. Among the more common aluminum alloys, 7075 alloy has the highest strength, but it cannot be welded and has very poor corrosion resistance. Many CNC machined parts use 7075 alloy. Zinc is the main alloying element in this series, and the addition of a small amount of magnesium alloy allows the material to be heat-treated to achieve very high strength properties. This series of materials generally contains small amounts of copper, chromium, and other alloys, with 7075 aluminum alloy being particularly superior, possessing the highest strength and suitable for aircraft frames and high-strength components.
