Probably such substitute is not possible. Anyway I am following and interested to get the better substitute.

composites definitely. even aluminum is not used in its pure form but as an alloy. most of the modern airliners structures is made up of composites these days.

Nano composite I guess

One biggest reason is non-corrosive nature of Al ...

Interesting article , they list other metals that can be used ...

Plastics over several decades slowly made their way from toys and jewelry to include serious aerospace and military applications. Plastic can be an easy choice when trying to save weight and cost. In September 2013, the American Society of Mechanical Engineers estimated, “in general, companies can expect to achieve an overall cost savings of 25% to 50% by converting to plastic parts.” Plastics can offer indirect benefits as well. A simple example is plastic grocery bags. Shipping one truck of plastic bags rather than four trucks of paper bags, for the same quantity, can save fuel, time, and storage space. However, plastics might not seem as likely a choice in higher-stress applications.

Interesting question

The solid Viberglass

Thank you Muhammad Saad Khan

Gaber Ahmed Ibrahim i was thinking of it before, but such polymers wont be able to withstand the strain and tempreture.

Thank you Aparna Sathya Murthy

May be from ceramics!

The Airbus A380 had many GLARE panels in its fuselage, Glass Reinforced aluminum is about 40% stronger than aluminum alone, while and while saving about 13% in weight.

I think there's a future for GLARE, even though the A380 project died a while ago.

Interesting! Following

composite materials are already being used.

Aluminum is used in the manufacture of aircraft structures because it is resistant to corrosion, lightweight and strong at the same time, as well as good economic feasibility compared to other materials. So I do not think the existence of alternative material in the near future.

thank you Isam Issa Omran

Thank you Ido Telio

thank you Joachim Pimiskern

better aluminium alloys? ;-)

• aluminium alloys (AA) still have a great future:
• AA 2198 (Al-Cu-Li) and the family of aluminiums 8xxx (Al-Li) are becoming increasingly used in aerospace industry in fuselage skin panels, etc.;
• AA 2219 is being used in the ISS;
• the first ground base in Mars will certainly be made of Al alloys since composites still have not enough damage tolerance;
• the Cu wiring will be substituted progressively by Al electric cables in many applications;
• 45% of the structure of many cars is made of casted Al alloys, and it is forecasted a growing use of Al in cars; and
• 3D printing and other techniques included in the category of additive manufacturing will become essential an many parts of cars and other structures will be manufactured this way, etc.

Hope this is useful!

Dear Saurav,

Carbon fiber is the most commonly used material.

Adding on to Ido Telio glass laminate aluminum reinforced epoxy (GLARE) could be a good alternative to aluminum. It is a fiber-metal laminate (FML) composed of several thin layers of aluminum and pre-impregnated carbon fiber bonded together using epoxy. It has multiple advantages over standard aluminum:

• It has better damage tolerance, especially in cases of impact and metal fatigue.
• Better corrosion resistance
• Better fire resistance
• And lower specific weight

GLARE has been used in the Airbus A380 fuselage and the leading edges of the planes empennage.

The article I have linked below includes more information on this topic.

It would be hard to find a substitute for AL. In fact, It took a long time for the extractive metallurgy to be able produce Aluminum element(Al) from its core,i.e. Al2O3, especially because of the high temperature necessary to melt the aluminum oxide, Tm= 2,072 °C . Those efferts eventually produced Al with unique physical/chemical properties.

Aluminum compaund used by the additive manufacturing.

Composite materials may replace aluminium in many cases.

Carbon fibers are now widely used in the aerospace industry to replace most of metallic parts

carbon fiber reinforced polymers (CFRPs) .
