7010 aircraft aerospace grade aluminum plate sheet is an improved aluminum alloy of 7050. The copper content is lower than that of 7050. It increases the content of alloy elements Zn and Cu, and increases the ratio of Zn to Mg content. Therefore, the alloy has high strength characteristics.
The aluminum alloy has the following characteristics:
- 1.Excellent compressive strength, high fatigue strength, good fracture toughness, high stress resistance and spalling corrosion resistance, excellent material hardenability, beautiful anodized surface.
- 2.Good shearing performance and riveting performance.
7010 aircraft aerospace grade aluminum plate sheet has excellent material properties and has been widely used in the aerospace industry. Its main uses are as follows: the production of A380 wing stiffeners (extruded parts). Widely used in processing equipment such as pre-stretched panels, large-size extruded products, large forgings, aircraft landing gear materials, suitable for aircraft skins, bulkheads, wing ribs, spars and other structural parts Make riveted parts.
