There are several metals that have a certain span of flexibility. It depends on the purpose the metal is being used for, and the shape the metal takes on. Aluminum, copper, and sterling silver, all have uses that require some flexibility. Springs made of steel can be considered flexible.
METAL
There are three main types of air ducts: sheet metal, pre-insulated, and flexible duct work. Sheet metal air ducts can be made of galvanized steel or aluminum, and may be insulated inside or outside with fiberglass. There are pre-insulated air ducts, which are relatively inexpensive to install, made of fiberglass duct board, polyurethane foam panels, or phenolic foam panels. Air ducts can also be flexible ducts, made of flexible plastic over a wire coil.

Depends on what shape they are manufactured in. E.g. springs, which are very flexible.
The smaller sizes are more flexible. Colder temps affect flexibility.

METAL
Flexible is a property of metal and not gases. Argon is a gas and cannot be flexible.
a flexible piece of metal
Yes it is. Rubber can be bend wherelse the metal cannot!
It is more likely to be a metal.
Non-flexible sheet metal piping
Flexible pipes can protect against somemovement.
is it permitted to use flexible metal conduit over 6 ft in length as a grounding means
Of course a paper cup would be more flexible. Nails are hard to bend.
Not unless heated.Answer:It depends on the metal and the physical shape of the object. Springs are obviously flexible, so are epee blades, bimetallic strips and wires. In all these cases the metal is deigned to be long in proportion to its width (has an appropriate aspect ratio).
