Aerospace aluminum 7075 is an aluminum alloy that has been cold treated and forged, resulting in higher strength than ordinary steel. 7075 aluminum alloy is one of the most powerful aluminum alloys used in commercial applications. It has a dense structure and strong corrosion resistance, making it particularly suitable for aerospace and marine applications. It has good corrosion resistance, excellent mechanical properties, and anodic reaction. The small grain size improves deep hole drilling performance and tool wear resistance.
The main alloying element in aerospace aluminum 7075 is zinc. Adding magnesium to the alloy containing 3% to 7.5% zinc can form MgZn2, which significantly enhances the alloy's strength and improves the heat treatment effect compared to aluminum-zinc binary alloys. Increasing the zinc and magnesium content in the alloy further improves the tensile strength, but reduces its ability to resist stress corrosion and exfoliation corrosion. After heat treatment, very high strength characteristics can be achieved. 7075 aircraft aluminum materials usually also contain small amounts of copper, chromium, and other alloys. Among this series, 7075-T651 aluminum alloy is particularly outstanding and is hailed as the best aluminum alloy product. It has high strength, far superior to any ordinary steel material. This alloy also has good mechanical properties and anodic reaction. Typical applications include aerospace, mold processing, mechanical equipment, and tool fixtures, especially for manufacturing aircraft structures and other high-stress structures that require high strength and corrosion resistance.
Aerospace aluminum 7075 is an alloy that has been cold treated and forged, resulting in high strength and hardness, far superior to ordinary steel. 7075 aluminum plate has good corrosion resistance, excellent mechanical properties, and anodic reaction. The small grain size improves deep hole drilling performance, tool wear resistance, and thread rolling prominence, making it the preferred choice for metal materials with low density requirements and high hardness.
