paglalarawan
7075 aluminyo plate (AA7075 aluminium sheet) ay isang aluminyo na haluang metal na may zinc bilang pangunahing elemento ng haluang metal. Ito ay may mahusay na mga katangian ng mekanikal at nagpapakita ng mahusay na pag -agas, mataas na lakas, kayamutan, at mahusay na pagtutol sa pagkapagod. Mayroon itong moderated formability kapag nasa ganap na malambot, Annealed Temper. Sa katunayan, grado 7075 aluminyo is stronger than many types of mild steel.
7075-Ang T6 aluminyo ay halos doble ang lakas-to-weight ng grade 2 Titanium
ang 7075 Ang Al Alloy ay pinaka -ginustong ng industriya ng sasakyang panghimpapawid. Ang komposisyon ng partikular na alloy na ito ay 5.1-6.1% zinc, 2.1–2.9% Magnesium, 1.2–2.0% tanso at mas mababa sa 0.5% ng silikon, Bakal, mangganeso, Titanium, Chromium at iba pang mga metal na bakas
Isa sa mga pangunahing dahilan upang isaalang -alang 7075 aluminyo is for its high strength. Alloyed kay Zinc, Ito ay isa sa pinakamalakas na haluang metal na magagamit at mas malakas kaysa sa 6061. Ngunit nag -aalok ito ng isang mas mababang antas ng paglaban ng kaagnasan kaysa 6061 at mas mahirap din na weld. 7075 ay ginagamit sa dagat, automotiw, at mga aplikasyon ng aerospace kung saan ang lakas ay isang napakataas na priyoridad. Ginagamit din ito sa pagmamanupaktura ng mga baril at ginagamit din sa mga frame ng hang glider
Sheet ng aluminyo / Ang plate 7075-T6/T651 ay karaniwang ginagamit para sa aerospace, militar, at mga aplikasyon ng automotiko. 7075 Ang aluminyo ay ang pinakamalakas na aluminyo, na may lakas ng maraming mga steels, habang pinapanatili ang magaan na katangian ng aluminyo at paglaban sa kaagnasan.

aluminyo 7075 is a member of the 7000 serye, 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.
haluang metal 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.
