2090-T83铝合金板材是一个完全商业化的铝锂合金，高度度开发航空航天应用。提供8％的铝 - 铜 - 锂合金的密度相比，节省与其他航空航天合金。铝合金2090-T83还具有较高的弹性模量的10％。何时加上密度小功能，提供了独特的轻量化的好处。

铝合金2090-T83都有自己的长处与其他高度度铝合金和优越耐腐蚀。该合金也是较焊接铝产品之一。

2090一些重大的功能变化，从传统的铝合金和需要考虑在设计和材料选择。具体细节进一步明确了在美铝公司的绿色2090铝合金。

A2090-T83用于商业用途的各种脾气，美国铝业公司已生产超过20万英镑的2090表。铝合金2090-T83表是专为使用高度度的要求是必要的。目前2090-T83板材被用于飞机地面舱壁扶强，采取高的优势强度和密度较低，实现了大幅减重。较初的用途包括机翼前缘和后缘，机身舱壁网和内部框架部分工作。

2090合金是许多应用，包括先进的飞机也正在考虑机翼结构。

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.
