2090T83ALLOY2090T83SHEET

2090-T83鋁合金板材是一個完全商業(yè)化的鋁鋰合金，高強度開發(fā)航空航天應用。提供8％的鋁 - 銅 - 鋰合金的密度相比，節(jié)省與其他航空航天合金。鋁合金2090-T83還具有較高的彈性模量的10％。何時加上低密度功能，提供了獨特的輕量化的好處。

鋁合金2090-T83都有自己的長處與其他高強度鋁合金和優(yōu)越耐腐蝕。該合金也是焊接鋁產(chǎn)品之一。

2090一些重大的功能變化，從傳統(tǒng)的鋁合金和需要考慮在設計和材料選擇。具體細節(jié)進一步明確了在美鋁公司的綠色2090鋁合金。

A2090-T83用于商業(yè)用途的各種脾氣，美國鋁業(yè)公司已生產(chǎn)超過20萬英鎊的2090表。鋁合金2090-T83表是專為使用高強度的要求是必要的。目前2090-T83板材被用于飛機地面艙壁扶強，采取高的優(yōu)勢強度和密度較低，實現(xiàn)了大幅減重。初的用途包括機翼前緣和后緣，機身艙壁網(wǎng)和內(nèi)部框架部分工作。

2090合金是許多應用，包括先進的飛機也正在考慮機翼結構。

Alloy 2090-T83 sheet is a fully commercialized aluminum-lithium alloy developed for high strength aerospace applications. The Al-Cu-Li alloy offers an 8 per cent density savings when compared  with other aerospace alloys. Alloy 2090-T83 also has a 10 per cent higher elastic modulus. When  coupled with the low density feature, this provides for unique weight saving benefits.

Alloy 2090-T83 has strengths comparable with other high strength aluminum alloys and superior

corrosion resistance. The alloy is also one of the most weldable aluminum products available.

Some material features of 2090 vary from conventional aluminum alloys and need to be consideredduring design and material selection. Specific details are further defined in Alcoa’s Green Letter  on 2090 alloy.

Alcoa has produced over 200,000 pounds of 2090 sheet in various tempers for commercial use.

Alloy 2090-T83 sheet is designed for use where high strength requirements are necessary. Currently。

2090-T83 sheet is being used for aircraft floor bulkhead stiffeners to take advantage of the high

strength and lower density to achieve a substantial weight reduction.

uses include wing leading and trailing edges, fuselage bulkhead webs and internal frame-

work parts. Alloy 2090 is also being considered for many applications in advanced aircraft including   wing structures.
