Aircraft Aluminium Sheet: 7075 Aluminum Plate

At present, with the rapid development of aerospace technology, the aircraft aluminium sheet and its composite materials are widely used in aerospace due to their high specific strength, excellent corrosion resistance and excellent formability.

7075 aluminum plate was the first aluminum alloy material used in aircraft in the late 1940s. After that, by adding other alloying elements, changing the content of its alloying elements and changing its heat treatment process, we get 7075 aluminum plate with different tempers.

As a stressed component of contemporary aircraft, 7075 aluminum sheet has the advantages of high specific strength, large yield ratio, and strong toughness. It will be a main kind of structural profiles for many industries in the future. But at present, its some shortcomings limit its further applications such as poor corrosion resistance and low fatigue strength.

7075 super-hard aluminum plate is a kind of aluminum-zinc-magnesium-copper alloy aluminum sheet. Its processing thickness is above 25mm. Because of its high strength to weight ratio, it is generally used in the manufacture of high-stress structural parts such as aircraft joints, fuse parts, instrument shafts and gears, missile parts, precision mold,etc.

To improve the properties of 7075 aluminum plate, Haomei Aluminum, a big 7075 aluminum plate supplier, has been testing in the following aspects:

• Apply rapid solidification and external fields (electromagnetic fields, etc.) during casting to make full use of alloy elements.

• Strengthen the research of furnace smelting technology, deepen the development of purification technology, reduce the internal impurity content of the molten pool.

• Develop aluminum-based composite materials to obtain composite coatings with excellent corrosion resistance.
