The lightest structural alloy I have heard about is Magnesium/Lithium Alloy. (and Mg/Na alloy)
It is used in airframes but has problems of long-term stability due to Li atom diffusion.
It is very combustible, and I do not know about its weathering properties.
The aerogels that Fountain mentions are foamed silicates and aluminates etc made with a supercritical solvent which is evaporated still above its critical point to avoid damage and collapse of the gel. They are not metals

Lithium is a metal, it looks like a metal, and with an atomic number 3, it is the lightest metal by far.
An alloy, Lithium Deuteride is used inside H-bombs.
I think that would be the lightest metal alloy in use.

Beryllium is the lightest structural metal out there (Lithium is anything but a structural metal). It's fairly strong, extremely stiff, and has a high strengthto weight ratio. Too bad it is a deadly poison and carcinogenic.

Lighter than steel - greater solid than steel - greater fee-effective than steel. regrettably, you are able to purely decide on 2 of those. Fiberglass sheet and carbon fiber composite sheet will meet the 1st 2 standards, yet they don't seem to be inexpensive, relatively carbon fiber. you are able to desire to objective deciding to purchase a chew of fiberglass on eBay if cost is a controversy. in case you do no longer discover between the applicable thickness, you are able to connect greater desirable than one piece jointly utilising fiberglass resin.

i could be wrong, but i am an avid tennis player and they advertise that aerogel is. they say a block the size of a human would weigh less than a pound and be able to support 4000 times its own weight... like i said, i could be wrong but its still amazing to me neway lol
