7075 Aerospace Aluminum Plate Aviation Sheet - 1/4 Inch Thick
7075 aviation aluminum plate is an aluminum alloy material with high strength, high hardness, excellent mechanical properties and corrosion resistance. It is widely used in high-tech fields such as aerospace and aerospace.
7075 aluminum plate has good mechanical properties, including tensile strength, yield strength and elongation. The tensile strength can usually reach more than 524Mpa, the yield strength is also more than 455Mpa, and the elongation is about 11%.
7075 aluminum alloy (AA7075) is an aluminum alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It has moderated formability when in the fully soft, annealed temper and can be heat-treated to strength levels that are comparable to many steel alloys. In fact, grade 7075 aluminum is stronger than many types of mild steel.
7075-T6 aluminum has nearly double the strength-to-weight of grade 2 titanium
the 7075 Al alloy is most preferred by the aircraft industry. The composition of this specific Al alloy is 5.1–6.1% zinc, 2.1–2.9% magnesium, 1.2–2.0% copper and less than 0.5% of silicon, iron, manganese, titanium, chromium and other trace metals
Aluminum Sheet / Plate 7075-T6/T651 is normally used for aerospace, military, and automotive applications. 7075 aluminum is the strongest aluminum, with the strength of many steels, while retaining aluminum’s lightweight qualities and corrosion resistance.

Aluminum 7075 is a member of the 7000 series, which has zinc as its main alloying component and is well known for its extraordinarily high strength. Tempering treatment can then further enhance its high mechanical strength. This property makes alloy 7075 very popular in the aerospace and defense industries.
Its strength is comparable to that of many types of steel, but it has a much lower density. The alloy is an excellent substitute to steel in high-stress applications. It also excels in withstanding fatigue stress, rendering it very reliable, a quality much sought after in the industries mentioned above.
Alloy 7075 offers only average corrosion resistance, an outcome of the small amount of copper included in its chemical composition. It also features reasonable machinability and poor forming and weldability. Another drawback of this alloy is that it has a comparatively high-cost relative to other aluminum alloys due to its exceptionally high strength.
